Terms: Antioxidant

Antioxidant refers to the ability of an ingredient to slow down, prevent, or block oxidation caused by the damaging effects of free radical activity.  The skin has its own antioxidant defense systems, but when the concentration of free radicals is greater than the capacity of the skin’s natural defense system, cellular damage occurs.  Antioxidants are added to cosmetics to increase the skin’s ability to protect against oxidation.
