Glutathione Ottimo Antiossidante Anti-age Glutathione at a glance Occurs naturally in skin Defends against environmental damage Offers restoring and tone-improving benefits Composed of three amino acids Glutathione description Glutathione is a powerful, non-enzymatic antioxidant which naturally occurs in the skin where it serves to help defend it against the visible effects of environmental damage. The gradual decline of the natural supply of glutathione in the body is believed to be a key marker of many outward signs of ageing. Glutathione is a tripeptide comprised of three amino acids (cysteine, glutamic acid, and glycine), which work in unison when used topically to brighten a dull complexion while offering skin-restoring benefits. It has value for visibly fading discolourations when used in a 2% concentration due to its ability to interrupt an enzyme within skin’s surface that triggers hyperpigmentation.
