Green tea extract contains catechins divided into four molecules with EGCG (Epigallocatechin Gallate) being the most potent one (30). This molecule acts as an antioxidant, helping to protect the skin from ultraviolet damage. With ECCG, you get increased collagen content, reduced wrinkles, smoother skin, and a thicker and more elastic epidermis (31).

This supplement can be obtained through drinking green tea or as an alternative supplement that specifies the amount of EGCG per capsule.
