What is this
Beta-Glucan
Beta-glucan is a naturally derived polysaccharide humectant found in oats, yeast and certain mushrooms. In skincare it binds moisture to the skin and forms a fine protective veil, helping skin look plump, smooth and comfortable — often compared to hyaluronic acid for its hydrating feel.

Questions about beta-glucan
What does beta-glucan do for skin?
Beta-glucan is a humectant that binds moisture to the skin and forms a fine, breathable veil on its surface. It helps reduce moisture loss, supports the skin's natural barrier and leaves the complexion looking plump, smooth and comfortable — with a distinctive cushioned feel.
Is beta-glucan better than hyaluronic acid?
They are complementary rather than rivals. Hyaluronic acid delivers a fast surge of surface hydration, while beta-glucan hydrates more gradually and adds a soothing, cushioning comfort. Some reports describe beta-glucan as even more hydrating at equal concentration; many formulas simply use both.
Is beta-glucan good for sensitive skin?
Yes — it is one of the most gently tolerated hydrators in skincare, well suited to dry, delicate or stressed-looking skin. Those with allergies to its sources, such as oats or yeast, should check the ingredient's origin before use, as a sensible precaution.
Where does beta-glucan come from?
It is a polysaccharide found in the cell walls of oats, yeast, certain mushrooms and grains. Cosmetic beta-glucan is purified from these natural sources into a clear, water-loving ingredient — plant- or ferment-derived, and suitable for vegan formulations depending on its origin.
