EGCG, the most active compound in green tea, works as an antioxidant that fights free radicals linked to wrinkles, dark spots, and sagging skin. Research shows it can help with acne, UV damage, skin brightness, and even some conditions like psoriasis and alopecia—though most dermatology applications are still emerging rather than fully proven.

This is a literature review that examined recent clinical studies on EGCG's uses in skin health and overall wellness. The authors compiled findings across dermatology, aesthetic medicine, and systemic health applications.
