Dr Bollmann, Skin Care Specialist, Anti-Aging Expert\r\nGlutathione is an effective antioxidant. The main effect in using it for skin whitening is most likely a side effect of making the skin lighter as it protects the cells from free radicals responsible for skin pigmentation and blemishes. Would a good sun block do the same thing?Bare Skin Care has this in our Anti-Aging Serum, but more for it's antioxidant benefits than for skin lightening. I ran this by our R\u0026amp;D expert and he found there is no scientific evidence to support glutathione as a skin lightening agent.Some dermatologists use IV glutathione, in 15 different treatments, for skin lightening. Is this an expensive gimmick? And even if it did work, it would seem it would be necessary to continue the treatment, and would not be permanent.\r\n\r\nThe main purpose of glutathione is to actually protect the cells of the body from harmful toxins. \r\n\r\nWhile glutathione is becoming popular as a skin lightener, especially among Asians, most stories about this being effective are anecdotal.\r\nFor treatment of hyperpigmentation, melasma, or brown (age) spots, our Program for Hyperpigmentation is every effective.
