8 Foods That Fight Wrinkles

Tomatoes are so much more than a pretty salad topping. They're packed with vitamin C, which helps build collagen and, in turn, makes your skin look firmer and plumper. They also have lycopene, which protects your skin from UV damage and improves your vascular system. According to Pace, after six weeks of eating tomatoes regularly, all that extra circulation will give you a noticeable glow.

Blueberries and raspberries are Pace's top picks. They contain flavonoids, polyphenols, vitamins, probiotics, and tons of antioxidants. "They're free-radical scavengers," explains Pace. If you're concerned with the effect your environment — anything from pollution to elements in your water — is having on your skin, add more berries to your diet. "They can even promote cell regeneration for new skin," says Pace.

In order to keep your skin looking as young as possible for as long as possible, your cells need to regenerate correctly. (Cells that mutate can lead to everything from uneven pigmentation to cancer.) "Green tea has lots of antioxidant power, as well as a chemical call EGCG," says Pace. "In multiple studies it was shown to help cells grow properly and maintain a healthy life cycle."

To fight redness and irritation, Pace recommends introducing foods with more probiotics, like yogurt, into your diet. "Skin-friendly bacteria in these foods condition your skin both inside and out," she says. Look for natural, unprocessed products to get the highest concentration of living probiotics. Kefir is a cultured milk product that's similar to yogurt, but has up to three times more probiotics than yogurt. You'll find it in the dairy case where it's often sold as a drink thanks to its thinner consistency.While medical researchers are still trying to figure out the link between gut bacteria and your skin, studies have shown that probiotics reduce inflammation and oxidative stress. Problems like acne, psoriasis, atopic dermatitis, and rosacea may all improve.

If your skin is chronically dry, add foods that contain healthy fats to your diet — they'll help moisturize your skin from the inside out. "Wild salmon is phenomenal for your skin," says certified nutritionist Suzie Carpenter. It's high in omega-3 fatty acids, one of the best fats for you. Other omega-rich fish include sardines and Atlantic Mackerel.

Nuts are another fantastic source of good fat. "It's the omegas in the nuts that are so good for your skin," says Carpenter. "Some nuts, like almonds, also have vitamin E." They have anti-inflammatory properties that can help with conditions like acne, psoriasis, and eczema.While walnuts contain the most omega-3s, all nuts, including almonds, hazelnuts, peanuts, and pistachios, are good for your health when eaten in moderation. Instead of a handful of chips when you feel hungry, swap in a handful of mixed nuts to see the skin-smoothing benefits.

Like nuts and fish, avocados have a lot of good-for-you (and your skin) fats, but it doesn't stop there — avocados are also high in glutathione. "Glutathione is incredibly anti-aging," says Carpenter. "I often recommend [it] for detoxing." By flushing toxins from your system, glutathione helps with acne and wrinkles, and it's even been shown to slow the development of certain cancers.

If you're craving something sweet, swap in honey for other types of sugar. "Honey is anti-viral, and it's an antioxidant," says Carpenter. "And even though it's technically sugar, it doesn't cause inflammation in your body and skin the way regular sugar does." It's so good for your skin, in fact, that you can even use it as a face mask.
