About





            

                
Green tea extract is rich in catechin polyphenols, particularly EGCG, which inhibits UV-induced MMP expression and reduces NF-kB activation. A systematic review found oral green tea polyphenols (250-1,080 mg/day) increased the minimal erythema dose by approximately 25%, providing internal photoprotection.

            

        

        

        
        
        

            

  
How It Works





            

                
Rich in catechin polyphenols, particularly epigallocatechin-3-gallate (EGCG); potent antioxidant that inhibits UV-induced MMP expression, reduces NF-kB activation, may protect against DNA damage, and modulates inflammatory cascades in photoaged skin.
