What Is Colloidal Oatmeal?
Colloidal oatmeal is a form of oatmeal used in cosmetics and skin care products. It is produced by finely grinding oats, then boiling them.
Research shows avenathramides, potent types of antioxidants found in oats (and colloidal oatmeal), can help soothe skin. A high concentration of beta-glucan and starches in colloidal oatmeal also mean it has water-binding properties and is an effective skin protectant. In fact, the United States Food & Drug Administration (FDA) categorizes colloidal oatmeal as a skin protectant, allowing it to be listed as an active ingredient on skin care products.
