Porphyridium Cruentum (Red Algae) Extract
What is Porphyridium Cruentum (Red Algae) Extract?
Porphyridium Cruentum Extract comes from a unicellular red microalga found in marine habitats. This botanical extract is rich in polysaccharides, proteins, and lipids, primarily used in cosmetics as a skin conditioning agent. It functions by forming a lightweight film on the skin's surface, which helps lock in moisture and enhances skin flexibility. Typically incorporated into moisturizers, serums, and creams at low concentrations, it supports the skin's natural barrier without greasiness. Derived through aqueous or solvent extraction processes, it provides humectant-like effects due to its sulfated exopolysaccharides, which mimic natural moisturizing factors. Authoritative sources like cosmetic ingredient databases confirm its role in daily skincare formulations for hydration and comfort.
