6 Foods That Can Help Slow the Effects of Aging on the Skin

While no food can prevent skin aging, certain nutrients may support skin hydration, collagen production, and elasticity.
“Diet is just one of many factors, however,” says Lawrence Green, MD, a board-certified dermatologist in private practice in Rockville, Maryland. Sun damage, exposure to pollution and smoke, illnesses that stress the immune system, and lack of sleep also contribute to aging skin, he adds.
Still, there are superfoods for skin health that may help you maintain healthier, more youthful-looking skin for longer.
Here are seven of the best foods for skin aging.
1. Avocado
2. Flaxseed
“Flaxseeds contain omega-3s, which also have been shown to reduce biologic aging,” Green says. “Foods rich in omega-3 and omega-6 fatty acids are less inflammatory and can help improve things like dryness, aged skin from the sun, and wrinkles.”
3. Fatty Fish
“It is reasonable to say that some of the [astaxanthin] compound is absorbed [when eating salmon], but that does not translate into saying that eating salmon can reproduce the skin effects seen with a concentrated supplement,” she says. “I still absolutely recommend salmon as part of a healthy diet because it provides protein, omega-3 fatty acids, and other important nutrients that support overall health.”
4. Berries
Blueberries are another berry to add to your diet, as they have been shown to have an anti-inflammatory effect. Some animal and lab studies suggest blueberries may increase skin hydration and elasticity, but more human studies are needed to be sure. Skin hydration is important because it keeps the skin looking plump and young, Dr. Kobets says.
5. Kiwi
6. Sweet Potatoes
Sweet potatoes are another food that may be promising in supporting skin health. They’re rich in antioxidants, including beta‐carotene, vitamin C, vitamin A, anthocyanins, and flavonoids, which may help combat oxidative stress, one factor involved in skin aging.
Sweet potatoes are worth eating because they are nutritious, and though the research connecting them with collagen production is plausible and interesting, it hasn’t yet been clinically proven, Kobets adds.
