Something touches your skin, and your immune system thinks it's under attack. It overreacts and sends antibodies to help fight the invader, called an allergen. The result is a red, itchy rash where the substance landed.

Allergic contact dermatitis is just like it sounds -- your body reacts to an allergy trigger.
People who have allergies react to things that wouldn't bother most others.Anything from plants like poison ivy to dyes and fragrances found in everyday products might be allergens.
You could also have an allergic reaction to something in the air that settles on your skin, like pollen, chemical sprays, powders, fibers, or cigarette smoke. This is called airborne contact dermatitis, and it mostly happens on your eyelids, head, and neck. It can be hard for doctors to diagnose because it doesn’t look that different from the other type.
