Botox isn’t the only way to erase those pesky expression lines—try adding more soy to your diet. Research shows that estrogen-like chemicals called isoflavones, which are found in soy, can keep your skin looking smooth and wrinkle-free.

After 12 weeks, women who took 40 mg of isoflavones not only had fewer crow’s feet, but their skin also showed improved elasticity (which keeps wrinkles from forming in the first place.) Talk about a double-acting secret weapon! Aim for one to two servings of soy per day to give your skin a boost. Soy takes many forms—whether it’s tofu, soybeans, edamame or that drip-feed soy latte of yours—so it shouldn’t be tough to squeeze in!
