Science
Mechanism of Action
Functions as a comprehensive skin protectant by neutralizing reactive oxygen species through its high concentration of flavonoids, tannins, and alkaloids. The extract inhibits key enzymes including acetylcholinesterase and lipase while protecting structural proteins like collagen and elastin from oxidative damage, simultaneously providing mild astringent and anti-inflammatory effects.
