Sodium carboxymethyl beta-glucan is a water-soluble, chemically modified derivative of beta-glucan used in skincare primarily for its hydrating, film-forming, and soothing properties, helping to support the skin barrier and reduce visible irritation. It is generally regarded as well tolerated and is used at low concentrations in serums, creams, and post-procedure formulations.
