How It Works: Three-amino acid tripeptide (gamma-glu-cys-gly). thiol group (-sh) provides electron donation for antioxidant activity and detoxification conjugation. shifts melanin synthesis from eumelanin (dark brown) toward pheomelanin (light yellow-red) for brightening. regenerates vitamins c and e from their oxidized forms.

SCIENTIFIC NOTE
Glutathione's melanin-shifting mechanism (eumelaninโpheomelanin) is entirely different from tyrosinase inhibition. even in the presence of active tyrosinase, glutathione shifts the enzymatic product from dark eumelanin to lighter pheomelanin by chelating copper from the tyrosinase active site and competing for dopa substrate.
