Almost everyone wants their skin to look healthy, rejuvenated and fairer. From home remedies to medical and cosmetic assistance, people try everything under the sun to improve their skin tone. Any discussion about skin whitening is incomplete without the mention of glutathione. Often referred to as the "Mother of all antioxidants", glutathione, a tripeptide comprising of the three amino acids - glycine, cysteine, and glutamine, also comes with detoxifying and anti-aging properties, and are extensively being used in the cosmetic industry.
 
Glutathione as a skin whitening agent
The pigment responsible for one's skin color in Melanin. The enzyme Tyrosinase plays a pivotal role in the synthesis of this pigment. In case of a darker complexion or an uneven skin, there is also an elevated production of Eumelanin (a pigment responsible for imparting the dark brown color). Glutathione goes a long way to inhibit the activity of the Tyrosinase enzyme which, in turn, slows down the production of melanin. Further, the antioxidant is also responsible for an increased conversion of Eumelanin to Pheomelanin (responsible for importing the yellow-red color), thereby lightening the skin tone significantly.
