A skin rash, or dermatitis, is an area of irritated skin. Rashes are often red and itchy and some are painful. A variety of irritants can cause a rash, such as poison ivy or an insect bite.
Contact dermatitis is a common type of rash. This happens when the skin comes into contact with an irritating substance. These can include certain soaps, detergents, fabric softeners and more. Allergic contact dermatitis is similar but occurs when your skin comes in contact with an allergen. Insect bites, poison ivy, poison oak and poison sumac are common allergens.
Treatment depends on the type of rash. Sometimes, no treatment is needed and the rash will heal on its own. Other times, topical steroids or other ointments can be used to treat contact dermatitis.
