lutathione (GSH) is a tripeptide — a molecule made of three amino acids — naturally synthesised by the liver and present in virtually every cell of the human body. It is often called the “Master Antioxidant” because it not only neutralises free radicals directly but also regenerates other antioxidants like Vitamin C and Vitamin E, amplifying their protective effect across the entire body.

In skin health, glutathione works by inhibiting tyrosinase — the key enzyme responsible for melanin production. When tyrosinase is suppressed, the skin shifts from producing dark eumelanin to lighter pheomelanin, resulting in a gradual brightening and evening of skin tone. Beyond pigmentation, it actively fights oxidative stress caused by UV radiation, pollution, and ageing — making it a comprehensive skin health solution, not just a lightening agent.
