Beta Glucans are polysaccharides found naturally in oats, fungi, seaweed and yeast. They are best known for its skin-soothing properties, showing excellent effects at reducing redness and other symptoms of sensitive skin. They do this via barrier-supporting properties, as they form a film on the skin’s surface to offer protection against daily environmental stressors, which can aggravate sensitive skin. They also stimulate macrophage function in the body (immune cells which fight invading bacteria), so offer added benefit to those with already compromised skin barriers more susceptible to bacterial infection, for example ezcema-prone or or drier skin types. Their polysaccharide nature makes them an effective humectant, meaning they can draw water molecules towards them to plump and hydrate the area.
