Oat Beta-Glucan Best Antioxidant Soothing Hydration Oat Beta-Glucan description Oat beta-glucan is a polysaccharide (complex sugar) that is derived specifically from oats. Beta-glucan can also be derived from various other natural sources such as yeast, fungi, and seaweed. It is commonly included in skin care products as a soothing agent and is considered an excellent ingredient for minimising redness and other signs of sensitive skin. Beta-glucan also offers antioxidant properties and has been shown to help visibly minimise signs of ageing/sun damage (including reducing the look of wrinkle depth and rough, uneven tone). Certain sources of beta-glucan also offer film-forming moisturising properties. In early research, it was hypothesized that beta-glucan’s high molecular weight would inhibit it from penetrating skin, thereby limiting its benefits to just the surface, but in more recent studies, beta-glucan has been proven to permeate skin by passing between cells. In 2012, the Cosmetic Ingredient Review Expert Panel deemed beta-glucan as safe in cosmetic formulations in the present practices of use at a 1% max concentration. Related ingredients: Beta-Glucan
