Science
Mechanism of Action
This extract functions primarily as a moisturizer by elevating the expression of hyaluronan synthase (HAS) genes, specifically HAS-2 and HAS-3, which stimulates endogenous hyaluronan (HA) production within keratinocytes. Beyond hydration, it exhibits anti-inflammatory, antimicrobial, and potent antioxidant properties. It also contributes to skin brightening by inhibiting the expression of tyrosinase and TRP-1 enzymes.
