Also known as: Oat Beta-Glucan, Yeast Beta-Glucan
Beta-glucan is a polysaccharide derived from oats, yeast, or mushrooms that acts as a powerful humectant and soothing agent. It activates skin immune cells (Langerhans cells), supports wound healing, and reduces redness. Often compared to hyaluronic acid for its hydration capacity, it also has documented anti-ageing effects through collagen stimulation.
Comedogenicity ratings are based on the rabbit ear assay model. Individual skin responses vary. See our article on comedogenicity ratings for context.
