Yale Medicine dermatologists have highly specialized expertise in treating complex skin disorders, including skin testing to determine the specific cause of a person's allergic contact dermatitis. “Someone will be, for example, exposed in the garden on Sunday, and then start noticing that they have an eruption on Monday. “Allergic contact dermatitis is something that's what we call a delayed type hypersensitivity,” says Keith Choate, MD, PhD, a Yale Medicine dermatologist. Contact dermatitis may appear flat or raised, and in severe cases, blisters filled with clear fluid may result.Īlthough some people react more quickly than others, these rashes tend to take time to develop and don't occur with the first exposure. The area is usually a pink or red color and feels itchy. The rash will arise at the point of contact with the allergen. This itchy skin rash can result from exposure to a chemical or compound that causes a response from the skin’s immune system. If you get a red, itchy rash with no known cause, it could be allergic contact dermatitis.
