Antioxidants are naturally-occurring ingredients that protect against free radical-generating environmental aggressors (such as UV rays and pollution).

An excess of free radicals in the skin can lead to inflammation and loss of collagen, resulting in dark spots, fine lines and wrinkles. Antioxidants neutralize free radicals, whilst offering a variety of other short-term benefits, depending on their type. Commonly found antioxidants in skincare include brightening vitamin C and strengthening vitamin E.
