Summary
Contact dermatitis is a type of skin rash that occurs when your skin comes into contact with an allergen or irritant. It is considered a type IV (delayed) hypersensitivity reaction, and commonly associated allergens include perfumes, cosmetics, latex, detergents, and plants such as poison ivy. Common symptoms include skin redness, swelling, itching, blisters, and dry skin. In severe cases, contact dermatitis can lead to cracks in the skin that may become infected.
