Research has shown the antioxidants in many types of algae, including red algae, help offset the oxidative damage UVB light exposure triggers. Red algae is a rich source of carrageenan, which in cosmetics serves as a natural thickening and gelling ingredient. Interestingly, the structure of carrageenan closely resembles glycosaminoglycans, which are a key part of skin’s barrier. In this capacity, the carrageenan in red algae can help deliver other ingredients throughout skin’s uppermost layers. Along with carrageenan, red algae is a source of plant cholesterol, whose fatty acid compounds benefit skin. Related ingredients: Algae Algae Extract
