What Is Epigallocatechin Gallate?
Plant polyphenols are widely found in the bark, roots, leaves, and fruits of plants. Broadly defined, plant polyphenols not only include tannins or tannic acids but also various small-molecule phenolic compounds in plants, such as catechins, vanillic acid, gallic acid, and ellagic acid.
EGCG: The full name is epigallocatechin gallate (EGCG), the most active component among tea polyphenols, belonging to the catechin class. EGCG is the primary component of tea polyphenols in tea leaves and the main component of the catechin class, which includes EGCG, EGC, ECG, EC, GCG, etc. 98% Epigallocatechin is a plant polyphenol extracted from green tea. Due to the polyphenol structure of plant polyphenols, they exhibit excellent ultraviolet absorption.
Epigallocatechin In Cosmetics
EGCG has antioxidant properties and can reduce UVB-induced erythema by inhibiting epidermal growth factor receptors and counteracting UVB-mediated phototoxicity. It also reduces ROS production in human skin leukocytes induced by UVB, protects the skin from UV-induced immune suppression, and prevents inflammatory skin diseases, photoaging, and photocarcinogenesis.
Green tea extract sunscreen uses 98% epigallocatechin as its raw material, reducing photoaging and lowering UVB-induced carcinogenesis. Green tea extract not only reduces UVB-induced carcinogenesis and inflammatory responses but also provides highly protective effects against UV radiation-induced skin oxidative stress.
