What it is

A polysaccharide from oats or yeast. Water-loving like hyaluronic acid, but the molecule is large enough to also form a thin soothing film on the surface.

What it actually does

Beta-glucan is a polysaccharide most commonly sourced from oats or yeast. It holds many times its weight in water like hyaluronic acid does, but the molecule is large enough to also form a thin, soothing film on the surface — so you get hydration plus a quieting effect on reactive skin. Recent K-Beauty essences lean on it as a hyaluronic alternative for sensitive types.
