Is colloidal oatmeal a good treatment for itchy skin?

Colloidal oatmeal is a recommended treatment or preventative for itchy, irritated skin caused by dryness, diaper rash or mild burns, according to WebMD. The product works by creating an oil barrier on top of the skin, which prevents moisture from leaving.

Regular use of colloidal oatmeal provides the best results, which is true of any moisturizer, states WebMD. It is best applied according to the package directions after showering before the skin dries. A doctor may recommend soaking the affected area before applying colloidal oatmeal, though frequent bathing can cause dry skin to become worse. If the skin condition does not improve with the use of colloidal oatmeal, the patient should seek medical attention.
