Beta-Glucan

Beta-Glucan is a polysaccharide composed of glucose molecules linked by β-glycosidic bonds, most commonly extracted from oat bran where it exists in high molecular weight forms. This natural biopolymer is valued in cosmetics for its unique ability to form a protective film on skin while penetrating into the stratum corneum, where it activates Langerhans cells and stimulates fibroblast activity. Formulators choose oat-derived beta-glucan specifically for its superior molecular weight profile (typically 1-2 million Daltons) and its dual action as both a skin barrier enhancer and a biological response modifier that supports the skin's natural defense mechanisms.
