Colloidal oatmeal has a long history of beneficial use in dermatology. It is a natural product that has an excellent safety record and has demonstrated efficacy for the treatment of atopic dermatitis, psoriasis, drug-induced rash and other conditions such as itchy, dry or irritated skin. FDA officially categorized colloidal oatmeal as a skin protectant in 2003 and has approved as an over-the counter (OTC) skin care product.
