Antioxidants

Antioxidants are substances that act as scavengers of oxygen-free radicals, the unstable particles that can damage cells and which are implicated in sun damage and even skin cancers. Antioxidants in the skin are depleted when exposed to sunlight and must be replaced.

Antioxidants are found in varying amounts in foods such as vegetables, fruits, grain cereals, legumes and nuts.
Antioxidant topical products (such ointments, creams, and lotions) may help reduce the risk of wrinkles and protect against sun damage. Unlike sunscreens, they accumulate in the skin and are not washed away, so the protection may last.
