Science

This marine extract is a powerhouse of nutrients, including vital minerals like zinc and copper, polysaccharides, and a spectrum of antioxidants such as sulfated polysaccharide chains and mycosporine-like amino acids. Its primary action involves deep skin hydration by enhancing the skin's natural moisture-binding capacity and strengthening the essential hydrolipidic barrier. The extract provides robust antioxidant protection, neutralizing environmental stressors and free radicals to actively combat the visible signs of aging. It stimulates the skin's natural production of collagen and elastin, which in turn promotes improved firmness, elasticity, and supports healthy cell renewal. With inherent anti-inflammatory capabilities, it can effectively reduce skin irritation and redness. Furthermore, it contributes to skin detoxification by aiding in the removal of impurities and minimizing pore congestion. The presence of calcium may also assist in regulating the skin's oil production. When subjected to hydrolysis, it liberates galactose and xylose, further enhancing moisture retention and cultivating a prebiotic environment beneficial for the skin's microbiome. In its powdered form, it can also act as a gentle exfoliant, visibly brighten the complexion, and offer protection against photodamage.
