Xanthan gum is a polysaccharide, a type of carbohydrate, that's commonly used in skincare products as a thickener and emulsifier to create stable and evenly textured formulas. It can improve the consistency and texture of creams, lotions and other skincare products to create a smoother and more pleasurable application experience. Xanthan gum is particularly valuable in formulas where it’s essential to maintain product integrity and prevent ingredient separation.
