Science

Mechanism of Action

This extract functions primarily as a powerful antioxidant, effectively neutralizing free radicals to protect the skin from environmental damage that leads to premature aging, fine lines, and wrinkles. It achieves skin brightening by inhibiting tyrosinase, the key enzyme in melanin synthesis, thereby reducing the appearance of dark spots. Anti-inflammatory actions, specifically through components like oxyresveratrol, are mediated via the MEK/ERK signaling pathway. Furthermore, it acts as an astringent to refine pore appearance and offers emollient and skin conditioning effects, forming a protective barrier to retain moisture and promote a smoother, more hydrated skin surface.
