Science
Mechanism of Action
Operating as a robust antioxidant, Undaria Pinnatifida Leaf/Stem Extract effectively neutralizes free radicals, thereby mitigating oxidative stress induced by environmental aggressors like UV radiation and pollution. Its skin conditioning properties are supported by polysaccharides, which are instrumental in retaining moisture, improving hydration, and reinforcing the skin barrier. Furthermore, it stimulates the production of vital skin proteins, collagen and elastin, contributing to enhanced skin elasticity and a firmer appearance. The extract also exhibits anti-inflammatory effects, calming irritation, and provides anti-pollution benefits by aiding in detoxification and external protection. Preliminary data suggests a potential role in skin brightening through dark spot reduction.
