Chondrus Crispus Extract

Chondrus Crispus Extract, commonly known as Irish Sea Moss or Red Algae Extract, comes from a species of red algae harvested along the Atlantic coastlines of Europe and North America. The extract is rich in carrageenan, a naturally occurring polysaccharide that gives it strong hydrating and film-forming properties. In skincare formulas it attracts and retains moisture, supports the skin barrier, and leaves a smooth, plump feel. It also contains trace minerals, amino acids, and antioxidants that add to overall skin conditioning. It suits most skin types, including sensitive skin, and turns up across leave-on and rinse-off formulations.

Evidence for stronger skincare outcomes beyond moisturization is modest. It performs reliably enough for a Good rating, though it doesn't quite reach Great.
