Beta-Glucan

Beta-Glucan is a soothing polysaccharide widely used in Korean skincare to calm redness, strengthen the skin barrier and support hydration. Derived mainly from oats or yeast, it forms a light, breathable film on the skin that helps lock in moisture without feeling heavy, making it a favourite for sensitive and reactive skin types.
