Powerful antioxidant • Skin lightening • Anti‑melanogenic
Glutathione is one of the most potent antioxidants, widely accepted as a skin-lightening and anti‑melanogenic agent. Present in cells in its reduced form (GSH), it plays a vital role in numerous physiological and biochemical functions. It inhibits tyrosinase activity—reducing dark eumelanin and promoting yellow-red pheomelanin synthesis—and counteracts UV‑induced melanin production.
