Science
Mechanism of Action
This extract functions as a powerful antioxidant, actively neutralizing free radicals generated by UV radiation, pollution, and oxidative stress, thereby mitigating signs of premature aging and supporting cellular longevity. It acts as a protective agent for collagen, reducing structural damage, while also exhibiting soothing and anti-inflammatory properties to minimize the appearance of fine lines, wrinkles, and hyperpigmentation. Furthermore, it aids in skin brightening by potentially inhibiting melanin production through tyrosinase and MITF down-regulation. Its polysaccharide content offers significant hydrating and moisturizing benefits, reinforcing the skin barrier and promoting the synthesis of essential proteins like elastin and collagen to enhance firmness and elasticity. The extract also demonstrates anti-pollution and detoxifying actions, protecting skin from external aggressors and optimizing mitochondrial function to support cellular detoxification and reduce oxidative leakage. It contributes to improved cellular turnover and stimulates collagen synthesis for enhanced skin quality.
