Red Algae
Red algae is a natural marine ingredient packed with vitamins, minerals and antioxidants. Commonly used in UK skincare and haircare, it helps hydrate, soothe and protect the skin while delivering a silky feel. It is especially popular in moisturisers, masks and serums for its ability to lock in moisture.
How it works in skincare
In cosmetics red algae functions as a humectant and film-forming agent, drawing moisture into the skin and creating a breathable barrier that helps prevent water loss. Its natural polysaccharides and carrageenan content give products a smooth, gel-like texture while delivering essential minerals and amino acids that support skin softness and elasticity. It is valued in British formulations for its lightweight feel and compatibility with sensitive skin.
