Beta-Glucan
By Nur → Last verified 9/26/2026
What it is
Beta-glucan is a polysaccharide often derived from oats or yeast, used in Korean skincare as a soothing, hydrating supporting ingredient.
What the evidence says
A soothing, hydrating ingredient studied for calming sensitive skin and supporting the barrier. It appears as a supporting ingredient rather than a headline active, confirmed in Round Lab's Birch Juice Moisturizing Serum alongside real ascorbic acid and licorice root, and in Dr.G's R.E.D Blemish Clear Soothing Cream alongside centella and madecassoside.
Who it's for
Sensitive or reactive skin wanting additional soothing support layered into a broader formula.
Worth knowing
No specific group needs to avoid beta-glucan, it's broadly well-tolerated.
