There is good news and bad news about the ingredient Glutathione. First, it is a natural substance that can be found in every cell in the body, and is essential in preventing a large number of diseases, including Parkinson’s disease and even cancer. While it has proven successful in many conditions, there is little evidence to show it has much effect as a skin-lightener, despite what brands such as Beauoxi White may claim. It does have a slight benefit in reducing the amount of Melanin in the body (Melanin is the substance responsible for dark skin pigmentation), but its primary function is in the area of anti-aging.
Glutathione must be taken with added Vitamin C to aid absorption, and this brand of skin-lightener does include the vitamin in the formula, along with Grapeseed oil. Alpha-Lipoic acid (which boosts the level of Glutathione), and Vitamin E. However, studies show that Glutathione is really only effective when it is either administered transdermally (for example, through a skin patch) or by injection rather than in an oral capsule, as it is Beauoxi White. Fortunately Glutathione is a very safe substance so taking it as a pill should not cause unpleasant side-effects. Rather, it would just be a waste of your money.
