L-Glutathione Reduced (GSH) is a thiol group containing tripeptide formed from glutamic acid, cysteine, and glycine. It acts as a powerful antioxidant, preventing damage to important cellular components caused by reactive oxygen species such as free radicals and peroxides.
Glutathione prevents the infiltration of tyrosinase to inhibit melanin formation. It is highly effective for eliminating wrinkles, increasing skin elasticity, shrinking pores, and lightening pigment. It has been a staple whitening ingredient in European and American cosmetic products for decades.
