Epigallocatechin gallate (EGCG), the principal catechin found in green tea leaves, is a well-studied polyphenol with potent antioxidant activity. It helps protect skin from oxidative stress by neutralizing reactive oxygen species, while also supporting a healthier-looking complexion by helping to reduce the visible signs of aging, including fine lines and wrinkles. In addition, EGCG has been associated with improved skin firmness and overall skin resilience, making it a valuable ingredient in formulations designed to promote a smoother, more youthful appearance.


Its antioxidant activity is linked in part to its phenolic ring structure, which helps it trap electrons and reduce reactive oxygen species
