Science

This red seaweed-derived powder delivers a complex of minerals like calcium and magnesium, critical for fortifying the skin barrier and optimizing lipid processes. It actively influences epidermal cell division, accelerating cell turnover for a visibly healthier complexion with diminished imperfections. Functioning as a gentle detoxifier, it helps purge impurities and prevent pore congestion. Its regenerating properties stimulate cell renewal, boosting collagen and elastin synthesis for improved firmness, elasticity, and a smoother skin texture, offering significant anti-aging benefits. The ingredient is a potent source of antioxidants, including polysaccharides, galactose, and xylose, which neutralize free radicals and shield cellular structures. Furthermore, its mycosporine-like amino acids (MAAs) provide natural photoprotection by absorbing UV radiation. Corallina Officinalis Powder also exhibits emollient qualities, enhancing the skin's capacity to bind moisture and supporting a healthy microbiome through prebiotic action. It supplies vital micronutrients such as zinc, which amplifies natural moisturizing factors (NMFs), and copper, essential for cross-linking collagen and elastin fibers. In its powdered form, it can contribute to product texture as a viscosity agent and offer mild physical exfoliation, promoting a brighter skin tone while reinforcing the hydrolipidic barrier.
