Glutathione (GSH) is an antioxidant composed of three amino acids (L-glycine, L-glutamic acid and L-cysteine). Antioxidants are chemicals that are able to donate an electron to a free radical, stabilizing the free radical and stopping the chain of chemical reactions and potential damage within the body. Some of the major reasons for free radicals in the skin come from normal chemical processes such as producing and using energy, unprotected sun exposure, products applied to the skin that produce free radicals and environmental pollution. This can lead to blemished skin and hyperpigmentation that can be attributed to aging. In fact as you grow older, your glutathione levels diminish on average 10-15% per decade so it’s very important that your system has adequate GSH levels to help counter balance the effects of free radicals. The side effects of taking high doses of glutathione (GSH) with vitamin C is associated with skin whitening.

How glutathione whitens skin? As a skin enhancer, glutathione needs vitamin C for better and long-lasting action. When taken along with vitamin C, glutathione can make the skin considerably fairer, firmer and much younger looking. The primary reason for the skin whitening effect is due to a reduction in the melanin formation of the epidermis which is tied to the enzyme Tyrosinase. This is a copper containing enzyme present in plant and animal tissue which is responsible for melanin production. Since glutathione inhibits the production of Tyrosinase this causes the skin to lighten-whiten.
