What It Does
Glutathione is a naturally occurring antioxidant in the skin that reduces hyper-pigmentation and brightens skin tone.
Why It Works
Glutathione is composed of three different amino acids (glutamine, glycine, and cysteine) that work together to neutralize free radicals and prevent cell damage. It also brightens and evens skin tone by deactivating the enzyme tyrosinase which produces melanin in the skin.
