Green Tea Extract
Green tea extract is a well-studied topical antioxidant with a long history of use in serums and moisturizers, generally well tolerated at cosmetic concentrations. Panel safety reviews of Camellia sinensis-derived ingredients have not identified meaningful topical hazard.
Some wellness commentary has extended reports of liver injury linked to concentrated oral green tea extract supplements (high-dose EGCG capsules) into a claim that green tea extract in skincare is similarly risky. Those hepatotoxicity signals come from oral megadosing, not topical cosmetic use, where systemic absorption is minimal and no comparable liver signal has been reported.
