Science
Mechanism of Action
Functions as a dual-action astringent and antimicrobial through tannin-mediated protein precipitation that contracts skin tissue and creates protective barriers against pathogens. Gallic acid and flavonoid compounds provide antioxidant defense while stimulating TGF-β pathways to enhance collagen production and accelerate cellular repair processes.
