Full Answer

A contact dermatitis rash is caused by direct contact between an irritant and the skin, states WebMD. Sometimes the rash results due to an allergic reaction to substances such as poison oak or fragrances in cosmetic products. Other times, it is caused by direct skin damage by products. In either case, patients should wash the skin immediately after they notice a rash developing. This helps remove the problem substance and reduce the severity of symptoms. For damaged skin, applying moisturizers several times per day helps restore the skin's protective layers.

For patients who develop rashes near their eyes or over large parts of their body, contacting an allergist is recommended, according to the American College of Allergy, Asthma & Immunology. He can prescribe stronger cortisone creams than those available over-the-counter. Patients are advised to continue bathing with soap and water daily when they have a rash, and to sooth rashes with a washcloth dipped in a mixture of cold water and baking soda.
