About

A hydrolyzed red algae extract — broken down for better absorption. Red seaweeds are rich in polysaccharides and minerals that hydrate and protect the skin.

Hydrolyzed Rhodophyceae Extract is the hydrolysate of an extract from red algae (Rhodophyceae class), produced by acid, enzyme, or other hydrolysis methods. Red algae are rich in sulfated polysaccharides (carrageenans, agar), mycosporine-like amino acids (natural UV absorbers), minerals, and antioxidants. The hydrolysis process breaks down large polysaccharides into smaller, more bioavailable fragments. Red algae extracts are widely used in cosmetics for their moisturizing, film-forming, and antioxidant properties. The class has a long history of safe use in food and cosmetics.
