Beta Glucan 1,3
Beta Glucan 1,3 is a powerful, natural polysaccharide used in skincare to soothe, hydrate and strengthen the skin’s barrier. It is a gentle yet highly effective ingredient that leaves skin feeling soft, calm and well-protected without any greasiness.
How it works in skincare
In cosmetics and skincare, Beta Glucan 1,3 works by forming a breathable film on the skin that helps lock in moisture while supporting the skin’s natural barrier function. It is prized for its ability to calm visible redness and irritation, making it a popular choice in sensitive-skin formulations, moisturisers, serums and after-sun products. Its film-forming properties also give a smooth, supple feel to the skin.
