What it is

Beta-glucan is a polysaccharide sourced from oats, yeast, or fungi. Cosmetic chemistry credits it with humectant action plus modulation of barrier resilience. Often positioned as a niacinamide-adjacent ingredient with stronger soothing character; K-beauty uses it in sensitive-skin essences and creams.
