Science

Mechanism of Action

This extract operates through multiple pathways to enhance skin health. Its high concentration of polysaccharides forms a protective, moisture-retaining film on the skin's surface, significantly reducing transepidermal water loss and ensuring sustained hydration. Fatty acids, including omega-3s, integrate into the skin's lipid barrier, strengthening its integrity and improving overall resilience, while also contributing to sebum regulation. Furthermore, its antioxidant compounds actively combat free radical damage, mitigating environmental stress and reducing inflammation.
