Epigallocatechin Gallate
What is Epigallocatechin Gallate?
Epigallocatechin Gallate (EGCG) is a natural flavanol polyphenol, specifically the ester of epigallocatechin and gallic acid, abundantly found in green tea leaves from Camellia sinensis. In cosmetics, it belongs to the antioxidant and skin-conditioning category, commonly incorporated into serums, creams, and lotions at low concentrations. It functions by neutralizing free radicals through its potent electron-donating properties, thereby preventing lipid peroxidation in skin cells and formulation oils. This mechanism helps maintain product integrity by slowing the degradation of sensitive ingredients exposed to air, light, or heat, while also contributing to a protective barrier against environmental oxidants on the skin surface.
