Porphyra Umbilicalis (Nori) Extract
What is Porphyra Umbilicalis (Nori) Extract?
Porphyra Umbilicalis Extract comes from a red seaweed species native to Atlantic coastal waters, related to edible nori. This botanical extract is produced via aqueous or solvent methods to isolate polysaccharides, polyphenols, carotenoids, vitamins, and trace minerals abundant in the alga. In cosmetic formulations, it acts as a skin conditioning agent, primarily functioning as a humectant that draws moisture to the skin and forms a lightweight film for prolonged hydration. Its antioxidant components help counter oxidative stress from environmental exposures. Commonly incorporated into creams, serums, and masks, it enhances product texture and supports skin barrier function. As a natural marine-derived ingredient, it aligns with clean beauty trends, offering gentle conditioning without heavy oils.
