Slide show: Common skin rashesBy Mayo Clinic staff
Contact with an irritant or allergen causes this form of dermatitis. Irritant contact dermatitis (A) usually produces a dry, scaly rash with a burning itch or pain. Exposure to a chemical, such as a cleaning product or industrial chemical causes this condition. The irritant will cause a rash on anyone exposed to it, but some people's skin may be more easily affected, and the severity of a reaction may vary with duration of exposure and the amount of irritant.
Allergic contact dermatitis (B) produces a very itchy, red rash with bumps and sometimes blisters. Common allergy-causing agents (allergens) include latex rubber, nickel, costume jewelry, perfume, cosmetics, nail polish and poison ivy. Allergic contact dermatitis affects people who develop an immune system sensitivity to the allergen.
Avoiding the irritant or allergen allows the rash to heal, and medications may improve symptoms.Next slide Previous slide
