Aside from one’s genetics and the skin sagging that naturally occurs with age, much of what is considered skin aging is really a result of exposure to pollutants and sunlight over time. Skin exposed to sun and toxins is damaged by unstable chemicals called free radicals. Antioxidants come to the rescue of skin ravaged by free radicals. Vitamins A, C, and E; green tea extract; and beta-carotene are antioxidants used in cosmetic products that are putting up a fight against wrinkle-causing free radicals.

It is believed that antioxidants stop potential damage before it occurs by interacting with free radicals as they penetrate through skin layers. Their role is prevention rather than repair of skin damage. Free radicals attack the lipids in skin which normally provide protection against moisture loss. Skin appears to age prematurely because of the resulting dryness and loss of elasticity. Antioxidants neutralize free radicals before they can break down lipids, and help protect skin from environmental agents, such as sun exposure, pollution and stress. Skin stays naturally hydrated and smooth with topical use of antioxidant-containing products.
