EGCG / Green Tea Catechin

INCI: Epigallocatechin Gallate (EGCG)

What is it?

The primary active catechin in green tea, a potent polyphenol antioxidant, distinct from the existing generic "Green Tea Extract" catalogue entry.

What does it do?

According to PubMed, a study developing an injectable collagen hydrogel physically crosslinked with EGCG found the hydrogel showed excellent skin compatibility and prolonged surface retention with moisturizing effects, leveraging EGCG's established skin-health benefits alongside collagen for topical delivery -- real formulation-science evidence for EGCG as a functional topical ingredient beyond its antioxidant reputation alone.
