What does the term “nighttime routine” bring to mind? If you’re a skin care aficionado, it may be your favorite part of your everyday routine. But if all the different products available to you feel overwhelming, don’t worry — we’ve enlisted the help of skin care experts to share the perfect nighttime routine for each decade of your life, from your 20s to your 80s.

Our skin changes over time due to various factors such as age, environmental issues, lifestyle changes and more. So it makes sense that the products a 20-something uses aren’t suitable throughout their life, and it’s important to make that distinction to support the skin’s needs. Our skin is our largest organ, after all.

The routines below serve as a general guide, depending on the needs of your skin during each decade of your life ― they cannot, of course, apply to everyone. But here’s one tip that does: Be gentle and have a consistent routine that won’t compromise your skin barrier.

“I always say to my patients: An ounce of prevention is worth a pound of cure. So it is always great to start incorporating key skin care ingredients early on, even before a problem develops,” Marisa Garshick, a board-certified dermatologist at MDCS Dermatology in New York, told HuffPost. She added that new products should only be added one at a time, and they should be layered from thinnest to thickest.

Having a basic, solid routine in your 20s is crucial. You can start by incorporating a retinoid to help with skin texture and to brighten your skin, according to Devan Jesmer, an aesthetician at Skin Remedy MD in north Texas. Plus, retinoids such as adapalene can help with breakouts that many people continue to have in their 20s, said both Jesmer and Garshick.

Even though we are focusing on nighttime routines, it’s worth noting that sunscreen should be part of your daily morning skin care.

“It’s always good to start the habit of sunscreen early and commit to it long term to get the most benefit,” Garshick said. “Sunburns, even in childhood and adolescence, can impact the long-term skin cancer risk.”

All the experts agreed on the importance of double cleansing, which thoroughly cleans the skin and removes makeup and sunscreen. If you’ve got oily skin, opt for a gel or foaming cleanser, and if your skin is on the dry side, choose a creamy or hydrating one, Garshick said. You can use two different cleansers for double cleansing — like a balm followed by a gel — or you can use the same cleanser twice.

Garshick’s proposed routine in your 20s:

By your 30s, a stronger retinoid (like retinaldehyde) is advised. A retinoid eye product may also be beneficial, Jesmer said, as well as weekly exfoliation.

“When introducing a retinoid into a skin care routine, it is best to start low and slow, only using it two or three times per week and gradually increasing the frequency,” Garshick said, adding the caveat that retinoids shouldn’t be used if you’re pregnant or breastfeeding. ”For someone with dry or sensitive skin, it may be best to apply the moisturizer prior to the retinoid to reduce the potential for irritation.”

During this decade of your life, “the skin tends to get a little bit drier and collagen levels are starting to slowly decrease, but visible signs of aging are still minimal. The goal is to maintain our collagen stores and even glowy complexion,” Cristina Psomadakis, a dermatologist in London, told HuffPost.

Garshisk explained that we actually lose 1% of collagen every year during our 20s, and this becomes more obvious in our 30s in terms of appearance and fine lines.

Jesmer’s proposed routine in your 30s:

In your 40s, focusing on replenishing collagen production is key.

“If you can get your hands on prescription tretinoin, this is the most powerful form of retinol on the market and available via your dermatologist,” Psomadakis said.

Cell turnover, which is our skin’s ability to renew its cells, slows down with age, and that’s why an exfoliating product might be beneficial. This will help remove dead skin cells from the skin’s surface, and the skin will appear smoother. An exfoliator can be a cleanser, exfoliating pads, toner or serum. If your skin is sensitive, pick your exfoliator carefully, something like mandelic acid or lactic acid, or a polyhydroxy acid such as gluconolactone, Garshick said.

“For those with more normal to oily skin types, glycolic acid or salicylic acid can be considered, respectively,” she said. “It is best to avoid exfoliating the same nights that you use your retinoid to minimize the chance of irritation and to limit exfoliation to one to two times per week.”

Garshick’s proposed routine in your 40s:

Skin laxity tends to be a big concern in our 50s, Garshick said, explaining, “People start to notice jowls forming as well as textural changes in the neck.”

It may be beneficial to add a separate neck cream in this decade. Other ingredients that may help include peptides, growth factors and antioxidants like resveratrol and vitamin C.

Garshick’s proposed routine in your 50s:

Psomadakis’ proposed routine in your 50s:

“Brown spots and hyperpigmentation are often a concern in your 60s, so while everything else still remains important, it is a good time to consider products and serums that also work to lighten discoloration and reduce pigmentation,” Garshick said.

The ingredients you should look into include antioxidants, alpha arbutin, tranexamic acid, kojic acid, niacinamide and azelaic acid. Retinoids continue to be essential as well as sunscreen in the morning.

Garshick’s proposed routine in your 60s:

The skin loses moisture as we age, so we have to replenish that with topical products and moisturizing creams, Garshick said.

“It may also be important to adjust the frequency of exfoliation, as well as the frequency and strength of the retinoid use if the skin begins to feel too dry, and look for products that help to repair the skin barrier,” she told HuffPost.

Garshick’s proposed routine in your 70s:

Hydration is more important than ever at this stage. Garshick recommended ingredients such as hyaluronic acid or glycerin, which contains humectants that will draw moisture in the skin, as well as firming peptides. For cleansing, a micellar might be preferred as a gentler option.

Garshick’s proposed routine in your 80s:

When in doubt, listen to your skin and consult a skin specialist who will be able to recommend products to suit your specific concerns. Also, remember that active ingredients such as retinoids take eight to 12 weeks of consistent use for noticeable results, so patience and consistency are key. If you catch any signs of irritation or sensitivity, strip back your routine to the basics.

My 90-something grandma is a badass boss who lives alone, takes care of herself and loves to cook. After working as a chef and nutritionist for close to 30 years, she could tell you how to make the perfect Cornish game hen like she’s giving directions to the local Dunkin’ Donuts.

Yet, as a party of one, she’s reluctant to buy bushels of herbs or large amounts of produce she knows she won’t use. That, coupled with COVID precautions keeping her away from the store, mean her menu has been looking a little bleak. So in the name of flavor and encouraging older folks to feel independent and strong, I’m gearing up to get her a meal delivery kit for the holidays. But with more options than there are Kardashians, it’s daunting to choose the perfect one.

According to Barbara Ruhs, a registered dietitian and founder of The Market RD, it’s imperative that older folks eat consistent, nutrient-dense meals. “As we age, some nutrients are not absorbed as well,” Ruhs told HuffPost. “Pre-made meals can make it easier for seniors to consume adequate nutrition.”

Retired physical therapist and home-health care specialist Cathy Ellis added that getting nutritious food delivered at home can help with recovery illness or injury. Rather than risking falling or being in public, older folks can have their pantry stocked from the inside of their own house.

Philly resident Shelby Guercio sends meal kit deliveries to her mom, who is 62, and grandmother, who is 100, in small-town Massachusetts. “My mom lives alone and works two jobs and is so busy that I worry about her being able to eat full, fresh meals after a long day of work or in between jobs,” Guercio said. “With meal kits just showing up at my mom’s door, she can either cook it quick and drop it off for my grandma, or easily bring the ingredients over and cook them at my gram’s house.”

Guercio said that sending over meal kits is easier than having her mom and grandmother drive a long way to the grocery store. Additionally, using meal kits means her mom and grandma are introduced to new foods they wouldn’t be able to get at their local store. “They live in an area where [meal] delivery takes an extra day, but still shows up fresh,” she said.

Chef Jake Minigiello says meal kits can be a low-stakes way to introduce older folks to different, but doable, ingredients and methods of cooking, especially because the pre-portioned ingredients allow you to try something new without committing to buying a whole container of it. “It’s good how they just send you the exact amount of ingredients you need for a recipe to cut that waste out,” Minigiello said.

Although meal kits may cut down on food waste, the packaging and shipping required has been the subject of criticism. And the costs of these kits can be a barrier for many shoppers. While delivery makes food more readily available, the high price points mean it’s only really available to those who can afford it. (It’s also import to note that Amazon Fresh, Top Box and Hungry Harvest, all listed below, accept EBT/SNAP.)

When exploring meal kit and food delivery options, you may also want to consider the work behind the scenes, and how those employees are treated. If worker’s rights are important to you as a consumer, find a brand that works for your kitchen and your ethics.

“Of course, a local, subsidized, sustainable alternative would be amazing, but let’s be real ― if that existed, it definitely wouldn’t exist [in rural areas] for all the old people,” Guercio said. “You can hardly even get Grubhub out there.”

It’s shortly after my 40th birthday, I’m enjoying some well-deserved time off with my family, and it’s shaping up to be one of the loveliest days I’ve had in a long time. We’d spent the day out in the water, and everyone was still lounging around in their swimwear by the time dinner rolled around.

At some point, the conversation turned to fitness. After years of yo-yo diets, watching what I ate, and berating myself with all types of internal verbal abuse, I was finally in a healthy space — mentally and physically. I was in a hot pink bikini, and I felt fly and fabulous. To celebrate and acknowledge that, I happily shared how I was feeling with my family: “I’m in the best shape of my life.”

Ten words were all it took to shatter the moment.

“That’s not true,” my brother scoffed. “I saw the cellulite on your legs.”

My face flushed immediately. My stomach dropped and the air rushed out of me. I was shocked. Then embarrassed. And then furious. His wife immediately called him out on making such an insensitive, backward and rude comment.

I simmered in anger but I also felt bad. Bad that my sister-in-law was arguing on my behalf. Bad that everyone in my family had heard my brother’s comment. Bad that my kids had to witness this ugliness.

My first instinct was to brush it off and manage everyone’s emotions so we could still salvage the evening. Fifteen years ago, Susan would have left it at that. But 40-year-old Susan? She was tired of constantly shouldering the invisible workload of women.

I shut my brother down. “Yeah, I’m celluLIT,” I responded before telling him that cellulite has zero to do with my fitness level or whether I deserve to feel good about myself. I’d been fighting body image issues for years, and my insecurities with aging were nothing new to me, but I was going to be damned if I let my kids grow up thinking that having cellulite or wrinkles was bad.

When I was a kid, I was no stranger to worrying about aging. I remember watching my mother stand in front of a mirror, nitpicking at her appearance as she noticed her skin sagging or wrinkling. I’d tell her she was beautiful.

“You won’t understand until it happens to you,” she would say. And oh, how right she was.

When I turned 38, I started noticing the first signs of perimenopause. Suddenly, I had to adjust my lifestyle. The way I ate and what I drank. And just as suddenly, I started noticing changes in my body. My skin sagging where it didn’t use to sag. Wrinkles appearing and deepening where they didn’t use to be.

Goodbye luscious hair, supple skin and strong bones, I thought to myself bitterly as I looked in the mirror, flashing back to the moments my mother would do the same.

But it wasn’t just my mother who hammered in these insecurities. There’s a $58.5 billion anti-aging industry that’s making bank off these thoughts.

You don’t want to be old, says every anti-aging cream. You want to be wrinkle-free, like me, says every airbrushed model image. You want to be desirable, says society.

Last year, a meme comparing Jennifer Lopez and Rue McClanahan from ”Golden Girls” went viral. Both aged 50, there was Rue in an old-fashioned maternal look versus J-Lo, dressed in a sheer and sequin costume, hanging off a pole at the Super Bowl.

Seeing that meme made me angry. Angry that we choose to celebrate women for their ability to look young rather than something more concrete. Angry that we continue to pit women against each other as well, over something as natural and uncontrollable as aging.

Between the ages of 38 and 40, I comforted myself by focusing on aging gracefully. I’ll be different. I won’t worry over my changing looks, I’ll embrace them and wear them with grace. But the aging part was still happening, graceful or not. And I still found myself scrutinizing my insecurities in front of the mirror as my mother had before me.

I thought aging was wrong because the media spent my entire life telling me so. Because society erases women over a certain age. Because actresses are airbrushed and Botox-ed while actors are called “mature” and ”stately” with their wrinkles. Because there is no space where an aging woman is shown in a positive light.

But you take away my age, and I am still a business owner, a badass entrepreneur who coaches women to their success. A lively, vibrant person. A friend. A mother. A partner.

I pushed myself to be mindful in the moments these insecurities would threaten to take over. I challenged myself to remember that I was fed this BS about aging. It wasn’t the truth.

I took a hard look at what I surrounded myself with online and started curating my space with content that would lift me up rather than minimize me. And as the male gaze began to shift off of me, I found it liberating to no longer be subject to society’s expectation of desirability or be boiled down to my reproductive value. This freedom started to incite a sense of newfound independence.

Worrying about aging, I soon realized, was stealing my youth. I was losing time, money, confidence and energy to it. Why hide my cellulite and stretch marks? My saggy skin and wrinkles? My body has carried me my whole life and the way it looks is my business.

Choosing to accept aging for what it is — a natural part of life — is one of the most empowering things we can do as women. In my refusal to let societal expectations push me aside, I found myself becoming bolder and louder and prouder. Clapping back instead of sitting in silence. Standing up for myself and my beliefs instead of meekly muttering excuses.

Since I have started mindfully rejecting the aging industry, my internalized ageism has melted away. I am no longer happy in spite of my aging body. I am thrilled to see my body evolve — just as it’s supposed to.

I still have moments of insecurity. Moments when I find myself in front of a mirror, staring a little too hard. But I choose to extend the same compassion I would extend to anyone else. I remind myself of the person I am, of the life I have lived, and the surety that there is still so much more to see, live and experience.

It’s not uncommon to get gray hair as we age, but of course humans want to reverse any sort of natural phenomenon the human body goes through that hints at our mortality. As such, there are products designed to stop those gray hairs from happening ― some supplements promise to prevent gray hair from coming in in the first place, while other topicals claim to reverse the gray. Even L’Oreal found reason to pursue the subject, announcing in 2011 that an all-natural pill would be out within five years that could prevent gray hair. (A rep from L’Oreal shared that it is no longer a focus area for their research and innovations team).

But as that abandoned project might hint at, the reality of preventing and reversing gray hair isn’t as simple as popping a pill—at least not yet.

While the mechanisms behind hair color are complicated, in the simplest terms, gray hair is caused by the loss of pigmentation. As we age, we produce less hair pigmentation, which results in gray hair. For the most part, when exactly this occurs seems to be genetically determined.

But there are some reasons gray hair may sprout sooner. Craig Ziering, board-certified dermatologist and founder of Ziering Medical, says that vitamin deficiencies, specifically of vitamin B6, B12, D, E or biotin, can accelerate the growth of gray hair. Oxidative stress from both internal factors (like an unhealthy diet) and the environment (like UV radiation) might play a role, too. Smoking has a significant effect: “Studies have shown that smokers are two times more likely to start graying before age 30 as non-smokers,” Ziering said.

Even hair products — including those used to color or bleach hair — can include ingredients that decrease the melanin in hair. “Hydrogen peroxide, which is in many hair dyes, is one such harmful chemical. Excessive use of products that bleach hair will also eventually cause it to turn white,” Ziering said.

Stress, too, seems to be a factor — think of the oft-mentioned comparison of presidents in their first year versus their last.

Keeping hair from going gray is big business — just take a look at the range of products available claiming to act as a gray hair treatment. But according to the experts we spoke with, the ability to reverse gray hair or prevent age-related color changes isn’t possible. “While certain nutrient deficits and health conditions may spawn premature gray hairs, it’s impossible to restore your natural hair color if your grays are genetic or due to natural aging,” Ziering said.

There’s reason to stay hopeful, though, if less gray hair is your goal. While most of what we know about gray hair says that once a hair is gray there is no going back, one study found that reducing stress just might help (easier said than done, right?). Researchers found that in some subjects, previously gray hairs repigmented after subjects went on vacation. The study has its limitations, but it illustrates for the first time that stress — and the reduction of it — actually can impact hair color.

“We can’t fully stop our hairs from going gray,” said Martin Picard, a researcher at Columbia University and author of the study. “This study shows that aging is malleable ― it is not a fixed, predetermined process we are doomed to experience in the same way no matter what we do. Our behavior, and perhaps how we learn to see the world and the stress we create for ourselves, seem to influence how our cells age, and when our hairs will eventually go gray.”

Besides reducing stress, there are some other tactics that might reduce the development of new grays — but only if lifestyle or nutritional deficiencies are the cause.

“Certain vitamins and minerals help ensure that your hair follicles have the maximum nutritional value to perform the metabolic functions in the bulb, one of which is production of the pigments (melanin) that the hair needs to retain its natural color,” Ziering shared. “Amino acids and proteins that trigger metabolic function in our follicles are beneficial,” he said. With that in mind, eating foods with the aforementioned vitamins can help, as can consuming antioxidants can counteract the effects of oxidative stress, like fresh fruits, green tea, olive oil, and fish.

“Eat well, sleep well, work against environmental stressors and avoid smoking,” Ziering suggested. “Use sun protection for hair and scalp. Boost calcium, protein, and B vitamins.”

As for those supplements claiming to prevent gray hair, technically they may work if they are making up for nutritional deficiencies, but no more than eating a healthy diet or taking a general multivitamin might.

Currently, treatments are being tested that have shown to reverse graying and repigment hair. “These agents include enzymes such as catalase which breaks down hydrogen peroxide, known to accumulate in the dermis of graying hair, so there may be treatment and prevention in the future,” Ziering said. “Looking ahead, this may someday be the foundation of a treatment which will reverse the exhaustion of the pigmentary potential of the melanocytes of hair bulbs,” he said.

“Not today and not tomorrow, but in the near future we may potentially unearth a ‘Benjamin Button’ effect resulting in restoration of richer, more youthful hair color for the 40s, 50s, 60s and beyond,” he added.

Picard is continuing to study gray hair as well. “I think we’ll learn more about the influence of the mind on the body. How our human experiences become embedded in our biology — in our hairs,” Picard said. “The mind and body are connected, and this shows us even in hairs!”

In the meantime, there is always the option to embrace the gray, which it turns out is the most stress-free method of all.

I remember when I was the youngest one in the room.

I was in my early 20s, working at my first professional job, and my colleagues were at least twice my age. I thought they were so much more sophisticated than I was. They had children, and money issues, and were concerned about their aging parents and their medical needs. My only stress was finding the right outfit for a Saturday-night date. I was free and clear with no real responsibilities other than paying my rent and getting to work on time.

When I was 22, and my parents were in their 50s, they had careers, traveled and went out with friends, but I still thought of them as incredibly old, and I couldn’t imagine ever being their age.

But life has a way of racing ahead, and 28 years later, I celebrated my own 50th birthday. I didn’t feel “old,” or any different than I had at 40 or 30 or even 20. But society had given me the message that being 50 was not something to celebrate.

The night before I turned 49, I was distressed, worried that in a year people would know I was 50, as if that number would somehow be branded across my face. I wasted time not enjoying that year because all I could think about was what was to come. That pressure that we feel to continue to be young can take its toll. Not caving into that pressure, and enjoying your life is what keeps you youthful.

I remember one of the first times I realized I had gotten older was when I walked near a construction site. The workers looked over my head and whistled at the 20-something woman walking behind me. I haven’t been whistled at in years, and even though I hated it, I missed knowing that I was whistleable (if that’s even a term).

Nobody wants to deal with sexual attention from creepy guys, but you don’t want to feel sexually invisible either.

As we age, most changes are subtle, and until we look back at pictures, we often don’t see them. Depending on our health, and our situation in life, we age at different rates. Some people don’t care about how their skin and body changes, while others fight it to the end.

When I saw my first gray hair, I couldn’t stop staring at it, because it took me a while to comprehend what that thing was that was growing out of my head. I was in my 40s, and as any parent will tell you, the easiest way to get gray hair is to have children.

Parenting is a hard job, and there’s no way to know how you’re doing at the time. (You can’t count when a 12-year-old tells you that you’re the worst because you took away their screen time.)

I now know my husband and I have done a good job. Not only do our young-adult sons like to spend time with us, but when we hand them petty cash, they respond, “No, thank you, I’m good.”

I still have the same energy I had in my 30s; even before I had kids. I still work out almost every day. The difference is now I’m one of the oldest in my weightlifting classes. But I’m also one of the strongest.

The women in my class are mostly in their late 30s and early 40s and have a gaggle of children. I spend weekends reading a book in front of a roaring fire while they’re at kids’ birthday parties. I’ll take getting older any day if it means not having to listen to one more person singing “Happy Birthday” to a screaming 3-year-old who doesn’t like loud noises.

When I was busy raising my two sons, I didn’t take time for myself. I didn’t have the time to exercise or relax with a cup of coffee unless I was willing to get up at 5:00 a.m., and I wasn’t giving up sleep for anything. Even my dogs got to the vet more than I got to the doctor. I did try to eat healthily, at least when I wasn’t eating leftover chicken nuggets off my kids’ plates.

But by the time I was 50, I no longer had to put everyone in front of me. I could now take care of getting that mammogram, seeing friends and traveling with my husband.

And not having to take care of getting dinner on the table for a picky child or having to help someone study the French and Indian War when I’d rather be watching “The Bachelor” never ceases to delight me.

As women, the number of years we’ve been on the planet can brand us. For those of us who took time off from our careers to have our kids, reentering the workforce at an older age can work against us. When you’re older, you bring wisdom and experience to any situation, so employers should rush to hire us. Many of us have raised families, know how to budget, are great at organizing schedules and have good communication skills.

Getting older also came with a new mindset. I used to concentrate on things I regretted that I had or hadn’t done. Like, why the heck did I stay with my high school boyfriend when he was obviously such a jerk? Now that I’ve lived many more years, those regrets have evaporated, because now I know that those choices have helped make me who I am today.

I also stopped caring what random people thought of me. When I was in my 20s, I wanted to be liked by everyone. I was also afraid to take risks. As I entered my 50s, I realized I have a voice and an opinion, and I’m not afraid to use either one.

So, much to my surprise, my life wasn’t over when I hit 50. Instead, I started a new chapter and reinvented myself: I became an author for the first time when my novel ”After Happily Ever After” was published. I didn’t go through any type of “crisis”; rather, it felt more like midlife empowerment.

Fifty didn’t mean I was going to slow down at all. In fact, I found myself busier than ever. I know plenty of women who published their first books in their late 60s or 70s, and I still have a long way to go to reach those ages. (OK, maybe not a long way, but I have a lot to do in the years before I get there.)

Now that I’m older, I wonder if when my parents hit 50 they also felt the renewed energy I’ve experienced. They were rid of their kids and could do what they wanted, when they wanted. They recovered the freedom they had before my sisters, and I were born. They could even run around the house naked ― although that’s not something I want to imagine.

So, maybe 50 is the new 35, and I’m good with that. But I’m also good with the idea that 50 is just 50. I’m in the prime of my life. I mostly do what I want. I am still a contributor to society, whether by writing my novels or by being there for my friends and family. I plan to keep doing all of that for many years to come.

There’s yet another skin care buzzword vying for its position as the Next Big Thing, but it’s highly likely you’ve officially reached “it”-ingredient fatigue. In this case, though, the it-ingredient sounds like it has some serious potential for repairing skin: stem cells.

In our bodies, stem cells create new cells and replace damaged cells. They can function as any cell in the body, which is one reason they are so powerful. While research is ongoing, stem cell therapies have the potential to treat diabetes, cancer, heart disease, Parkinson’s disease and more. But they are also controversial: Today’s approved therapies extract stem cells from embryos. (Adipose- and bone marrow-derived stem cells, which come from live, human donors, are also available ― although applications of these are limited and not currently approved for therapies by the Food and Drug Administration.)

That brings us to stem cells in skin care. Despite the capability of stem cells, the claims made by stem cell skin care products aren’t much different than you’d find on a bottle of any other anti-aging product: diminished wrinkles and fine lines, firmer skin, smoother texture and more even tone. But stem cells, at least in theory, should do even more than that ― they excel at repairing skin and stimulating the growth of tissue, even where skin is damaged.

The products don’t come cheap. There’s the $135 Indie Lee stem cell serum. Or the more affordable Juice Beauty Stem Cellular anti-wrinkle overnight cream for $75. You could try the Lancer Skincare Lift Serum Intense for $275, which also has pure 24 karat gold in it.

If these products really do harness the power of stem cells, perhaps the cost would be worth it. But do they actually work? According to Beibei Du-Harpur, a dermatologist and skin researcher (and a dermatology registrar and Ph.D. candidate in the U.K.), “There is no evidence that stem cells in skin care could be helpful, at present.”

Jordan Wang, medical research director at the Laser and Skin Surgery Center of New York and a board-certified dermatologist who’s published several papers on stem cells in dermatology, explained, “Frequently, the marketing is over-exaggerated and solely meant to increase sales irregardless of the science.”

“Unfortunately, the term ‘stem cell’ is highly marketable, but the products do not have robust peer-reviewed science behind them. The studies I have seen are very small and appear to be aimed at convincing an audience that has no scientific background,” Du-Harpur said.

Flawed studies aside, one of the biggest problems is that the stem cells in your serums aren’t actually from humans. Instead, the stem cells are often derived from plants ― anything from apples to echinacea to various flowers.

“There is less convincing data on the benefits of plant-derived stem cells as it pertains to skin health, and there are many questions on if their use truly translates to worthwhile and noticeable results,” Wang said. One issue is that plant stem cells effectively speak another language than our own stem cells, and therefore they are unable to communicate with each other in the way our own stem cells can.

“There is no theoretical reason why this would have any benefit on human skin,” said Du-Harpur, referring to plant stem cells.

Other times, formulas contain byproducts of stem cells without containing any stem cells themselves. This might be on the label as “stem cell conditioned medium,” which is basically the waste product of stem cells. Growth factors are also a commonly used stand-in for stem cells, sometimes called EGF, or epidermal growth factor. Growth factors are a protein that can stimulate cell growth and speed up wound recovery. While stem cells replicate themselves to create new cells, EGF tells cells to replicate to stimulate new growth.

“Although such compounds from certain types of stem cells such as mesenchymal stem cells have ‘anti-inflammatory’ effects, the research behind these products and formulations have not been extensively peer-reviewed,” Du-Harpur said.

While so-called stem products typically don’t actually include stem cells at all (at least any that our cells could communicate with), there’s a big problem with the idea of including them in an over-the-counter product in the first place: how difficult it is to maintain live stem cells.

“Another issue is the stability of stem cells in topical formulations, where breakdown and viability are significant concerns,” Wang said. To survive, stem cells need extremely controlled environments, which is something they don’t get when bottled into the creams and serums for consumers today.

“The way they are maintained in labs is to keep them in a dish at 37 degrees [Fahrenheit], with a very specific soup of substrates, enzymes, etc., which are constantly being changed,” Du-Harper explained. “Even so, they have a limited life span in this environment. The likelihood of a cosmetic formula being able to replicate this is pretty small.” (Du-Harpur added that if a stable formula were created, there’s no evidence that even this would provide anti-aging benefits. “Skin is a barrier, and the stem cells would not penetrate the barrier,” she said.)

As a final note, when discussing stem cells there is an obvious moral issue. Not only because of the difficulty of obtaining stem cells, but also because of their potential capabilities. “If we could harness the theoretical regenerative power of stem cells into a skin care product, it would be utterly unethical of doctors to NOT use them in the myriad of life-changing dermatological diseases that would benefit from them,” Du-Harper said.

“The claims made by companies who have products that are ‘stem cell’-related often sound very impressive,” Du-Harper said. “If their product was truly able to deliver some sort of skin regeneration, there would surely be a social responsibility to make available their technology for people who have a serious need for it, e.g., those who have been disfigured by burns scarring, patients with genetic skin fragility and chronic wounds.” Currently, however, there is no treatment or usage guide from reputable dermatologists that actually use stem cell therapies, because this kind of remedy does not exist.

That could change in the future, given the current research. “Stem cells are being actively researched to develop treatments for debilitating skin conditions and treat currently untreatable conditions,” Du-Harpur said. But these treatments aren’t just a cream or lotion that you can buy off a shelf, and certainly won’t be used for smoothing wrinkles or firming skin. Treatment would likely be delivered via injection and would have to go through many levels of approval and testing first. “Although there is great promise, it is an area of medicine (regenerative medicine) that is in its infancy,” Du-Harpur explained.

If you’re looking for the sort of treatment you wish stem cell products delivered, the good news is there are ways to effectively coax your own stem cells into repairing your skin. And if you use retinoids or peels, or have gotten laser treatments, you already have. These procedures remove the top layer of keratinocytes, or skin cells. When this happens, stem cells in your skin create new skin cells. “The effect of this is commonly described as ‘increased cell turnover,’ which actually means your stem cells are speeding up its rate at which it forms a new keratinocyte,” Du-Harpur said.

Until research catches up — and issues of morality and packaging are sorted out — the most effective way to treat skin is probably the way you’ve already been doing it. When it comes to stem cell products, save your money.

You’ve been so good about taking care of your face — slathering on sunscreen, remembering your night cream and making time to get facials regularly. But your hands may be making you look older than you’d like.

“Hand anti-aging measures should start early in life, because the face and the hands are the most sun and environmentally exposed areas of the body,” said dermatologist Cheryl Burgess.

If you’re noticing sun spots and bulging veins, you could always try treating your hands with the same over-the-counter TLC as your face. But some people are taking more drastic measures and turning to a cosmetic procedure that can give their hands a more youthful appearance: hand lifts, aka hand rejuvenation.

“Just as we can revolumize the face, we can do the same thing with the hands,” said Joshua Zeichner, a dermatologist and associate professor of dermatology at Mount Sinai Hospital.

If you’re thinking a hand lift is a face lift for your hands, you’re not quite on the right track. We talked to experts to explain the process.

Your hand are frequently exposed to the elements — and they have a more delicate composition than you might have realized.

Dermatologist Janiene Luke, an associate professor at Loma Linda University, explained what’s going on with your body: “As our collagen production decreases with age, the skin can become thinner, making underlying veins and tendons more visible. We can also lose fat and subcutaneous tissue, while the small muscles that are in the hands can be prone to atrophy. Sun damage can become cumulative over time, causing sun spots to become more prominent. And some people have a tendency to have small benign growths on the hands, too.”

These treatments target the backs of the hands, not palms or fingers.

“Good candidates for these treatments may be people who have noticed that the skin on their hands has become very thin and that their bones and blood vessels are prominent, giving the hands a skeletal appearance,” said dermatologist Arianne Shadi Kourosh.

Dermatologist DiAnne Davis said patients are increasingly seeking out hand treatments.

“With the exception of the face, the hands are one of the most expressive parts of the body,” she said. “Given that everyone is working from home more often these days, their hands are a lot more visible on their computer and tablet screens, especially if they use them while talking.”

You may have a pretty good understanding of the nip-and-tuck procedure that’s part of a face lift, but a hand lift is an entirely different matter. It’s not a surgical procedure, and the skin is never cut. In fact, nothing is “lifted” at all. Instead, doctors will most likely recommend a course of treatment that includes filler injections.

The process starts with some numbing cream or lidocaine, Davis explained. Then come the injections.

“Small entry points are made on the back of the hands in between tendons and bones, and small amounts of either hyaluronic acid filler or biostimulating agents are slowly injected,” she said. “The product is then gently massaged so that it can be evenly distributed throughout the entire back of the hands.”

A hand lift can cost anywhere between $2,000 and $4,000, depending on what is done and the volume of filler that’s used, according to facial plastic surgeon Michael Somenek. He said people who receive hyaluronic acid filler, which is the most common, can expect to see results last for nine months to a year.

If you’re considering a hand lift, it’d be a good idea to do some research and probably to have a consultation with a doctor.

“It often takes several syringes to give you enough volume to make a meaningful improvement,” Zeichner said. “The cost per vial of the filler ranges depending on what you’re using and what part of the country you live in. On average, costs vary from $800 to $1,000 per syringe. Optimal results may take several syringes.”

Some patients may benefit from a combination of hand treatments, including use of a laser to target a specific area.

“I tend to do a couple of procedures for hand rejuvenation,” Luke said. “I’ll inject filler but also do something like Intense Pulsed Light, a treatment that targets the melanin in the sun spots and addresses the surface of the skin to improve its overall appearance.”

Zeichner said laser treatments work well for people who have dark spots or crepey skin, and that there are different lasers for different issues.

“We have lasers that can lighten dark spots and others that can resurface the skin,” he said. “My go-to laser for the back of the hands … works by punching microscopic holes in the skin, creating a controlled wound and taking advantage of the skin’s natural wound healing process. This stimulates collagen to thicken the foundation of the skin, and it also helps the skin shed darkly pigmented cells to lighten hyperpigmentation and even skin tone.”

“None of these treatments are a substitute for good skin care habits over time,” Kourosh said. “It’s important to moisturize the hands and apply sunscreen each morning to the backs of the hands in order to prevent and minimize the damage from the sun and harsh exposures.”

Davis suggested using moisturizers with vitamin A derivatives to help stimulate collagen production. If you want to boost your hand care regimen even more, she said you might want to consider supplements of biotin, also called vitamin B₇, which can help with the appearance and strength of nails. “Certain lightening ingredients, such as kojic acid or niacinamide, also can help reduce the appearance of brown spots on the back of the hands,” she said.

It’s not news to anyone that women have to prove their worth at almost every stage in their lives. While it’s already challenging enough for women to claim their rightful place in professional fields that are saturated with men, the struggle is also there within their own community, especially in the world of beauty influencers.

The value of beauty bloggers and influencers has historically been dictated by a woman’s age, with younger women attracting most of the lucrative work in the field. So what’s it like once those young women grow up and want to continue their life’s work at a more advanced age?

We talked with fabulous beauty bloggers and influencers over the age of 45 who are #proaging, slaying their professional game and influentially educating everyone on what it’s like to age gracefully and naturally. Here’s what they have to say about their journey in the beauty industry.

Gail Hanlon

Founder of Is This Mutton?, a U.K.-based fashion and beauty blog for women over 50

I definitely attract different brands, and in the main they are brands that are specifically tailored toward older women. The first challenge is getting brands to see the value in using older women in their marketing and advertising. There’s nothing more infuriating than seeing face creams for “mature skins” being advertised by girls in their 20s.

Secondly, most of the brands have a blind spot when it comes to older women and social media. They occasionally “like” a picture we may have posted showing ourselves wearing a new lipstick, but they rarely share it. This makes me think their social media teams are probably young people in their 20s who don’t want to taint the brand with pictures of older women. Yet the women behind brands like Charlotte Tilbury, Pat McGrath Labs and Lisa Eldridge are women in their 40s or older.

Thirdly, the brands’ social media teams seem to want only Instagram or TikTok. The number of women over 45 on those channels is nowhere near as big as it is for younger people. Many influencers with huge followings bought their followers when this was possible. If you analyze their numbers, half of their followers are either bots or men. Fashion brands have started to see the light: We see more diversity now on the catwalks. But beauty brands seriously lag behind.

The final challenge is the wording they use when they target products at women over 45. Anti-aging? Why are so we so against aging? We all get older, nothing stops that. We need to embrace aging and stop bullying older women into thinking they have to turn the clock back and look younger in order to be acceptable.

Blogger behind Beauty Blog Over 40

I was under 40 when I started my beauty blog, but as soon as I hit the big 40 I noticed that big brands (that actually specialize in anti-aging) like Olay, It Cosmetics or L’Oreal would rather work with younger influencers and completely stopped working with me. And most makeup brands have no interest working with women over 40 ― it’s almost like they think only young women use makeup. But I do love makeup and so do many of my followers! The same is true for PR agencies ― they cater to the 20-to-30-year-old influencers.

I don’t know if younger bloggers make more money than I do ― this is a big secret and nobody is actually talking openly about that.

Blogger behind Amanda Ramsay, a popular Australian beauty blog especially for women over 40

I didn’t intend to be an influencer. I’m an experienced professional makeup artist who simply saw a gap in the market ― no one here in Australia was talking to this huge collection of women. They were greatly forgotten, ignored or left to feel inadequate. I’ve got the skills and experience as a pro artist to share my knowledge, and the passion to make sure women get the right info, without the marketing BS, so they can remain seen, feel fabulous and rock on at every age.

So I guess it’s different over 45. Beauty PR is more focused on the younger generation of influencers, but I see that as a reflection of the whole industry. The beauty industry’s narrative has been youth as the only definition of beauty, and scaremongering the more “mature skinned” beauty into being fearful, like there is something wrong with aging.

I suspect as brands catch up to the notion, beauty PR and brands will seek out us older birds. The wave of change is coming, albeit a little slow, but the pro-age movement is gaining traction!

Blogger behind Fab Over 40

Things have changed greatly since I started blogging in 2008. When I started, I researched who was blogging for beauty and skin care for the over-40 market and there was absolutely no one I could find. I don’t think PR and marketing firms knew how to handle it. For the most part, I was ignored, and a few years later I started getting noticed, but I would get countless pitches daily on things like “get the look of Kim Kardashian” or celebrities in their 20s. I would oftentimes respond either asking if they had anything that would be of interest to my age market, but most wouldn’t acknowledge my requests.

I was mostly offered free product to test ― all without compensation. Once in awhile I would be compensated, but nothing like younger bloggers get now. It would be a big deal if I got $100 for testing and promoting a product. I think the challenges are just having your voice heard in a manner you are comfortable with. I don’t want to hype a product that someone is pushing me to get the word out there if it’s absolutely nothing I would use or anyone in my age group would use. Sure, the latest seasonal makeup release is fun and pretty, but is it something women over 40 would even wear? If it is, I’m all for sharing about it.

Mary Zavaglia

Makeup artist, stylist and journalist

When I first moved into this space of work I felt out of place, as the younger bloggers all looked the same — very “Kardashian” — almost plastic-looking. I felt intimidated and dreaded anyone asking me my age! But slowly I decided that I didn’t have to fit that mold. I embraced being bolder, not older, and found my own tribe of bloggers/influencers and I looked forward to going to my launches. I was so flattered when the younger bloggers started to approach me and ask me for my beauty and hair tips! It was then I realized that we all have a space to work in.

For PR brands, youth sells. Yet, it’s interesting that PR agencies are slow to acknowledge that it’s the older demographic that have the money to spend and they relate to someone like myself touting a product or showing them how to apply the latest light reflecting or blurring product. Being an over-45 blogger/influencer has so many wonderful advantages. For one, I have a much larger audience to cater to, so I have far more opportunities.

Daphne Kapetas

Chemist, blogger and the founder of Lajoie Skin

Skin care advice from a woman over 45 who has aged well, in my experience, is something that a younger age group does respect ― especially when that person has obviously not resorted to fillers or injectables. When I was a young chemist working for one of the largest cosmetic companies in the world at the time, I remember how disappointed I was when the face of Lancôme, Isabella Rossellini, was dropped not long after she had just turned 40.

My diverse experience and qualifications are a huge advantage, but this can only be earned with time. But PR agencies and advertisers traditionally do use younger people, even when it comes to trying to target to an older audience. If we look at the sheer number of younger versus older bloggers, they do not represent our society, but then the same can be said for other marginalized groups.

Dawn Gallagher

Former ’80s supermodel and micro-influencer

Being a beauty blogger/influencer over the age of 45 is different! It’s different in the sense that many brands are finally starting to recognize that this age group has the disposable cash and can afford to spend it on items and products they like. I am attracting all kinds of brands that are finally recognizing that beauty comes in all ages and that beauty is truly how you feel inside, and we can always enhance our natural beauty with makeup, skin care and hair care.

My brand is growing and my work has increased dramatically as a vlogger/blogger. When it comes to money, I’m not really sure how much younger bloggers make, but I am paid very well for my services. However, I still struggle to convince brands that it is a great investment to recognize this demographic and the potential it can produce for them with ROI (return on investment). The advantages I have are that I am one of the very few beauty blogger/vloggers in the space and my Youtube channel has received over 4 million views and counting. It helps that I have been a beauty and wellness expert for decades.

For people of a certain age, these are the wonder years — the years when you look in the mirror and wonder, “What happened to my face?” If the children’s story “The Saggy Baggy Elephant” is starting to hit a little too close to home, you might want to see how our panel of experts can help you understand what’s happening and what you can do about it.

Yes, you can blame the matrix, no matter which color pill you took. “The structural foundation of your skin is provided by something called the dermal extracellular matrix,” dermatologist Brandon Kirsch told HuffPost. “This matrix is composed of molecules such as collagen, elastin and glycosaminoglycans, also known as hyaluronic acid, which is an active ingredient in skin fillers. Aging and environmental factors such as sun exposure, stress, pollution and smoking lead to the breakdown of these substances, leading to wrinkles, crepiness and sagging skin,” he added.

The face you have today is not the same one you had yesterday. “Our face is kind of a moving target, with changes over time in the bones of our skull, as well as the fat and muscles underneath the skin,” dermatologist Arianne Shadi Kourosh, assistant professor at Harvard Medical School, told HuffPost. “Loss of these underlying support structures that are holding up the skin, and shifting of the fat from our cheeks downward toward the jowls and jawline, can add to the sagging appearance of the face.”

Gravity is great for keeping us, well, grounded, but it’s not our friend when it comes to sagging skin. “The facial bones that provide a framework start to resorb and lose density and structure, so it’s like the hanger holding up the garment loses its strength,” dermatologist Corey L. Hartman told HuffPost. “Youthful fat pads also start to shrink and disappear, leading to the decrease of another layer of deep, structural support.”

There are simple changes you can make to prevent even more sagging, the experts say. Here are some suggestions:

“A sugary diet can cause a process called glycation of collagen, in which sugars bind to it and accelerate the sagging and aging of the skin,” Kourosh said. “Drink enough water and maintain a healthy, low-glycemic index diet,” Hartman suggested. And knock off the sauce, too. “Alcohol is a diuretic, which means it will deplete your body’s natural store of water,” Kirsch said.

“This further weakens the skin, and it creates textural irregularities and pigment changes, as well,” Hartman said. “Avoiding exposure to first- and secondhand tobacco smoke is of critical importance, since that smoke contains a high concentration of free radicals, which are highly oxidative and damaging to all human tissue,” Kirsch said.

“Chronic exposure to ultraviolet light causes reduction in collagen and elastin, as free radicals contribute to an increase in matrix metalloproteinases that further degrade collagen, which gives our skin firmness,” Hartman said. “Commit to using daily sunscreen with SPF 30 to 50.”

Weight Loss

“Massive weight changes, especially weight loss, can affect the skin’s sagginess,” dermatologist Janiene Luke told HuffPost. “There may be redundant or excess skin when a large amount of weight is lost suddenly.”

There’s no such thing as a facelift in a jar, but there are some products that might help. “Certain ingredients in topical creams can be helpful in small and gradual ways,” Kourosh said. “But they’re limited in the depth and extent of their effects.”

“While topical products do not give the same results as a cosmetic procedure would, there are some that are effective and can help improve the appearance of aging, sagging skin,” Luke said. “Many of my patients are either afraid of or not interested in undergoing surgical procedures or facelifts, so they’re more inclined to try products or non-invasive procedures.”

“Although few results are documented with high-quality and objective evidence, based on my decades of clinical experience, it’s clear that limited benefits for sagging skin can be achieved with topical products,” Kirsch said. “These topicals work primarily to stimulate the formation of collagen, elastin and other structural components of the skin matrix. In addition, good moisturizers, when used in a regimented manner, can provide modest improvements by hydrating the skin.”

When you’re shopping, Kouroush said she tells her patients to “take a scientific approach, read labels and look for the right ingredients that have evidence behind them.” Here are some ingredients the experts said to watch for:

Antioxidants, Plant Extracts And Peptides

“Antioxidants scavenge free radicals that cause a breakdown of collagen, and they act as a cofactor in the production of new collagen,” Hartman said. “Antioxidants like Vitamins C and E, as well as plant extracts and peptides, have been used with some success to address the various pathways involved in sagging skin,” Kirsch said. “They target the extracellular matrix to address the loss of supportive structure and elasticity, and the antioxidants protect against contributing environmental factors.”

“Antioxidants such as Vitamin C and niacinamide have been shown in the literature to increase collagen production,” Luke said. “Peptides are amino acids that can penetrate the skin and signal our cells to produce more collagen and elastin.”

“Some eye creams contain caffeine because it’s a vasoconstrictor, which means that it shrinks blood vessels,” Kourosh said. “This helps because it reduces blood flow, which decreases inflammation and redness and ‘depuffs’ swollen areas of skin. Some slimming or cellulite creams also can contain caffeine or xanthene stimulants, which are found in cocoa beans, tea and yerba mate. It’s also possible that regular massaging of the cream into affected areas improves circulation and the appearance of the skin.”

“These are the building blocks of a healthy skin barrier, like the mortar that secures the ‘bricks’ of skin cells,” Hartman said.

Growth Factors

“They promote healthy, efficient production of key proteins in the skin,” Hartman said.

Hydroxy Acids

“Also called fruit acids, these are some of the most widely used and studied anti-aging skin care compounds,” Kirsch said. “When applied to the skin, they increase epidermal proliferation, thickness and hydration. Clinical trials have shown the effectiveness of these ingredients in reversing the effects of photo-aging and improving wrinkles, skin elasticity, tone and hydration. The two main classes to look for are alpha hydroxy acid, such as glycolic acid, and beta hydroxy acid, such as salicylic acid.”

“The highest level of medical evidence supports the use of retinoids such as retinol, tretinoin, adapalene and tazarotene,” Kirsch said. “They’re closely related to Vitamin A, and they’re well-recognized for their ability to stimulate collagen production and enhance the appearance of skin by effacing fine wrinkles, lightening age spots, firming skin and improving surface texture. They also imbue the skin with a flattering, rosy glow.”

“They can help slow the sagging process, especially in those who use them regularly for months to year,” Kourosh added.

There’s been plenty of Tokyo 2020 headlines about Hend Zaza, the Syrian table tennis prodigy who, at 12 years old, is one of the youngest Olympians of all time.

But there’s some striking personal stories on the other side of the age spectrum, too.

Oksana Chusovitina, a 46-year-old gymnast from Uzbekistan, impressively competed in her eighth Olympic Games last week. Chusovitina, who competed in a sport dominated by teenage athletes, received a standing ovation after performing in what she said would be her last Olympics.

Then there’s Australian equestrian Mary Hanna, who at age 66 is the second-oldest female athlete in Olympic history and the oldest Olympian competing in Tokyo.

Through their efforts, Hanna and Chusovitina are changing the conversation around age and agility. They’re proof that you can compete or put yourself up to a physical challenge way past what is considered “your prime,” said Michael Stones, a professor emeritus at Lakehead University in Ontario, Canada, who researches healthy aging and physical performance.

“It’s terrific that this year’s Olympics includes so many younger and older athletes,” he told HuffPost. “They show that age alone is not an insurmountable barrier to excellence in physical activities.”

These Olympians also lend the games some experience and maturity, especially in team sports, said Sandra Hunter, a professor of exercise science and director of the Human and Athletic Performance Research Center at Marquette University in Milwaukee, Wisconsin.

“These older athletes can help mentor the younger ones, particularly with all the mental and psychological challenges that we’ve seen,” she said. “They bring a level of maturity to the teams and surrounding athletes that allow the younger athletes to learn.”

Below, we spotlight 10 older Olympians who are giving it their all at the Tokyo Summer Games.
