What it does

Colloidal oatmeal is one of the better-studied soothing ingredients in topical care. The avenanthramides (oat-specific polyphenols) have measurable calming activity on inflamed skin. Used in eczema-supportive moisturizers, post-procedure recovery products, and gentle baby formulations. The FDA recognizes colloidal oatmeal as a skin protectant ingredient in OTC monograph products.
