What to eat: Foods that are packed with vitamin C (like kale and berries), as well as eggs, beans, seeds, goji berries, and avocados.
“Kale, as well as most berries (like blackberries, blueberries, raspberries, cranberries and strawberries), have tons of vitamin A, C, and calcium which are all good for skin. But, it’s specifically their high content of vitamin C, a powerful antioxidant, that makes it an especially good food for fighting premature aging due to UV damage,” explains Lynch. “Plus, there are 45 different flavonoids in kale, all of which have antioxidant and anti-inflammatory properties.” Lynch’s go-to recipe when you just can’t eat another salad: kale chips. Bake them on a baking sheet for 10 minutes with some olive oil and freshly ground pepper. And, don’t stop there to get a natural skin smoothing effect. “Eating a mix of foods that are rich in collagen-boosting ingredients such as embryonic foods that contain amino acids (eggs, beans, and seeds), antioxidants (pomegranate and goji berries), and good fats (walnuts and avocado) inhibit damage to collagen, so skin stays smoother for longer,” says Murad, who suggests having at least a half a cup of low glycemic fruit daily, whole eggs (try two for breakfast), almonds and pecans (about a handful a day) to get the anti-aging skin benefits
