Glutathione is the body’s most powerful antioxidant, unknown by most. It is popular when used as a way to help whiten skin though. Glutathione skin whitening is growing in popularity, helping people achieve the skin pigmentation they desire with no harmful side effects when taken in proper dosages. Glutathione help to whiten the skin in a couple of different ways. Melanin is the pigment that gives our skin its colour, produced by the activation of the enzyme Tyrosinase. Gluthathione binds to Tyrosinase and helps prevent the enzymatic pathways from producing melanin. The second is a much more important role. GSH helps to prevent the activation of Tyrosinase by reducing free radicals in the body that can activate it and cause an increase in melanin production.
