Contact dermatitis is a form of eczema that develops after the skin comes in contact with a substance that acts as an irritant or allergen. The affected areas become red, inflamed, and itchy. Swelling, blistering, crusting, and oozing can also occur. Irritant contact dermatitis is the more common type, with a rash developing after repeated exposure to an irritant such as a cleanser or soap. Allergic contact dermatitis can occur when a person is exposed to an allergen such as poison ivy, nickel, or certain ingredients in personal care products. Treatment includes avoiding irritants and/or allergens, establishing a gentle skin care routine, and using prescription medications.
