What is Carrageenan (Chondrus Crispus)?

Carrageenan is a thickener made from seaweed. It’s derived from a species of red algae common along the Atlantic coast of Europe and North America.

Carrageenan is boiled in order to extract a polysaccharide rich gel. In skincare, this gel is used as a thickening agent. It also hydrates and cools the skin.

Not to be confused with degraded Carrageenan.
