hydrolyzed rhodophycea (red algae) extract
Hydrolyzed rhodophycea is a type of red algae that, like most other types used in skin care products, helps improve skin’s hydration and ability to look healthy while also being a good source of antioxidants. 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.
