At some point or another, nearly every woman wishes she could turn back the clock and take better care of her skin sooner. According to an , that desire has turned into dollars: the anti-aging market was worth $215 billion in 2016, and it's predicted to become a $331 billion empire by 2021. Not only are there creams, masks, and serums taking over store shelves, but supplements also consistently claim to reverse the visible signs of aging.
It's tricky territory though. After all, you can't tell right away if these products are actually working. And , M.D., author of , says that the science behind beauty vitamins is “soft,” meaning it lacks a lot of concrete evidence. But she does note that more supple skin can be achieved by consuming a combination of antioxidants (such as vitamins A and E), as well as beta carotene, lycopene, and omega-3 fatty acids. You can get these by eating whole foods — a sentiment the agrees with wholeheartedly.
While Whitney Bowe, M.D., author of , also agrees — noting that our stress levels, sleep, and dietary choices all impact the health and appearance of skin — she says that supplements can also play an important role in aging well, especially if you're not getting enough nutrients through your diet. If that's the case, experts recommend talking to your doctor about potentially adding these anti-aging products to your shopping cart.
The number one rule for younger-looking skin: protect your largest organ from the sun, since ultraviolet (UV) light breaks down the extracellular matrix in between your cells and speeds up aging, says , M.D., a dermatologist at Schweiger Dermatology Group in New York City. That's why she recommends an anti-aging supplement that contains an extract from a Central American fern known as Polypodium leucotomos — it's been shown to increase the amount of time it takes for the skin to burn from the sun's harmful rays, reports the (AAD).
“My patients [a common skin condition that is characterized by gray-brown spots] swear by Heliocare,” Dr. Bowe adds. “Once they start using it, they finally see their skin start to brighten and their tone [evens] out.”
However, Dr. Bowe emphasizes that . Plus, the reported level of protection to meet the AAD's recommendation to use an SPF of 30 or higher, so yes, you still need to slather on coverage.
Suggested serving: Other than wearing sunscreen every single day, both doctors recommend taking one pill each morning and an extra pill on days when you’ll be spending a lot of time outdoors. Whenever you're shopping for supplements though, remember to do your research. "These are not heavily regulated by the FDA, so you want to use reputable brands [as] quality and ingredients do vary," Dr. Bowe says.
This essential trace mineral is most known for boosting immune system function and aiding in wound healing, but both Dr. Skotnicki and Dr. Greenfield say it may also protect the skin from UV damage. Research published in the found that a zinc deficiency in rats led to impairments in DNA repair caused by free radicals, which can speed the aging process.
Of course, these findings don't necessarily translate from rats to humans, but it does encourage further study. Especially since a review published in concluded that, while the current evidence on zinc's efficacy is limited, what is available looks promising.
Suggested serving: The (NIH) states that adults should not exceed more than 40mg of zinc per day.
3. Coenzyme Q10
Also referred to as CoQ10, this antioxidant compound — which the body naturally produces to help convert food into energy — has some science that suggests it may help reduce wrinkles and improve the texture of the skin, Dr. Skotnicki says. For example, a 2018 medical review published in the journal found CoQ10 supplements may alleviate age-related issues, including an increase in oxidative stress (damage in the tissues and cells caused by the environment) brought on by a CoQ10 deficiency. A small study published in also had 33 adults take a daily supplement for 12 weeks (either 50mg or 150mg), resulting in "significantly reduced wrinkles" and an improvement in skin smoothness.
Suggested serving: There isn't currently an established recommended dietary allowance (RDA) , and not everyone is deficient in CoQ10 so you may not even need to take a supplement. (Remember, the body naturally produces the antioxidant, though that process does slow down as you age). Also, while the has labeled this supplement as “generally safe,” there can be potentially harmful side effects, including blood clots, so be sure to talk to your doctor to make sure it's right for you.
4. Collagen Peptides
There are two amino acids in the protein collagen — proline and glycine — that are essential for the formation and repair of joints, bones, muscles, and tendons, Dr. Bowe says.
But they also help skin retain its firm appearance. A study published in evaluated the effects of collagen peptides on the skin of nearly 70 women, and found that those who consumed between 2.5 and 5 grams of collagen for either four or eight weeks showed a significant improvement in skin elasticity compared to those who took a placebo.
Suggested serving: While the body has the ability to process up to 30 grams of protein every few hours, Dr. Bowe suggests tossing one tablespoon of a collagen powder into a smoothie, coffee, or soup.
5. Vitamin C
Everyone touts vitamin C for its abilities to ward off colds and flu, but this potent antioxidant may also improve skin's texture and appearance. Sometimes referred to as ascorbic acid, Dr. Bowe says it stimulates collagen production that can, in turn, help reduce fine lines that may have been brought on by environmental stressors, like sun and heat exposure or pollution.
While it's well known that can have a skin brightening effect, scientists are now digging into the efficacy of supplements. suggest that high doses may treat skin discoloration when delivered intravenously, and an association between consuming more vitamin C (along with more omega-6 fatty acids and less saturated fat) and fewer wrinkles and crepey skin.
Suggested serving: The NIH says that the , but adult women are advised to consume at least 75mg of vitamin C each day, with thetopping out at 2,000mg. Dr. Bowe recommends patients take a daily supplement of 1,000mg.
