Juicy and tart Montmorency cherries are your best source of the antioxidant melatonin. Other cherries have it, too, but Montmorency has the most. Melatonin protects the skin against ultraviolet radiation. Researchers have discovered that this powerful little nutrient also helps repair sunburned skin, since it stimulates new skin-cell growth. Cherries are also packed with vitamin C, which is needed to build collagen—your skin’s natural “scaffolding” and a wrinkle preventer.
