Science

Mechanism of Action

This extract acts through several pathways to improve skin health. Its rich content of polyphenols, flavonoids, and piscidic acid provides potent antioxidant defense, neutralizing free radicals and mitigating oxidative stress to prevent premature aging. It calms irritated skin by blocking stress markers from sensory nerve cells, thereby reducing redness and inflammation. As a natural humectant, it effectively attracts and retains moisture, enhancing skin hydration and suppleness. Furthermore, it promotes a brighter and more even skin tone by inhibiting melanin production and significantly reducing tyrosinase activity, which contributes to reducing dark spots. Anti-aging benefits include stimulating collagen production, increasing TGF-β mRNA expression to help reduce wrinkles, enhance skin elasticity and firmness, aid in wound healing, and promote cell proliferation.
