In addition to getting more vitamin C in your diet, you may want to apply it topically too. When applied to the skin directly, the antioxidant neutralizes free radicals that contribute to damage and premature aging. Free radicals are molecules with an unpaired electron, and when they steal an electron from one of the proteins in a strand of collagen, it creates a tiny break in the strand. The more breaks that occur, the more damage you’ll see in your skin, including wrinkles. As vitamin C is an electron donor, it can help reverse and prevent those signs of aging.
