Formula IngredientAntioxidantErgothioneine
INCI: Ergothioneine
Ergothioneine (EGT) is a naturally occurring amino acid derived from histidine, found in mushrooms, certain bacteria, and other organisms. It is a potent antioxidant that accumulates in tissues exposed to high levels of oxidative stress. In skincare, it protects against UV-induced damage, pollution, and other environmental stressors. It is increasingly used in vitamin C serums and anti-ageing formulations to boost antioxidant protection.
