Sun protection: Lycopene (found in tomatoes), polyphenols (in green tea and pomegranates), resveratrol (in red wine, grapes, and peanuts), and cocoa flavonoids can prevent damage from UV rays.

Antiaging: Hyaluronic acid, coQ10, collagen, and vitamins A, C, and E may support skin-cell health and collagen production to stave off environmental damage that can cause wrinkles.

Dry or irritated skin: Omega-3s and probiotics may help soothe from the inside. Research shows that in addition to digestive benefits, friendly bacteria may fight dermatitis.

Hair and nails: As natural components of skin, hair, and nails, collagen and silica strengthen and grow these areas.
