What is Beta-Glucan?

Beta-Glucan encompasses a class of polysaccharides made of glucose units connected by beta bonds, sourced from natural materials such as oats, barley, yeast, mushrooms, and algae. In cosmetics, it falls under skin conditioning agents and bulking agents. It works by creating a lightweight film on the skin to lock in moisture, enhance texture for smoother application, and support the skin's natural barrier. Commonly featured in creams, serums, lotions, and masks, it improves product stability and spreadability while contributing to a soft, supple feel. Its humectant action attracts water molecules, aiding hydration without greasiness. Derived through extraction or fermentation processes, beta-glucan suits a range of formulations, from daily moisturizers to post-treatment soothers, aligning with preferences for gentle, multifunctional ingredients.
