Glutathione is a tripeptide consisting of cysteine, glycine, and glutamate and functions as a major antioxidant. It is synthesized endogenously in humans. Glutathione protects thiol protein groups from oxidation and is involved in cellular detoxification for maintenance of the cell environment. Reduced glutathione (GSH) has a skin-whitening effect in humans through its tyrosinase inhibitory activity, but in the case of oxidized glutathione (GSSG) this effect is unclear. We examined the skin-whitening and skin-condition effects of topical GSSG in healthy women.
Glutathione Reduced means that the powder is of a further reduced molecular size making it easier to penetrate the skin and get to where it is needed.
It has been shown that the presence of glutathione can inhibit cell death induced by hydrogen peroxide, a powerful oxidant formed during UV irradiation. The amount of glutathione is lower in aged skin. Although skin aging is clearly a multifactorial process, data indicate that the concentration of intracellular glutathione is very important and that depletion of this concentration may play a significant role in the progression of cellular aging in human skin.
Glutathione Reduced is safe and effectively whitens the skin and improves skin condition in healthy women.
