Contact Dermatitis is a type of skin inflammation characterized by red, itchy rash caused due to exposure to allergens or irritable substances. As the outer epidermal layer gets damaged, it leads to irritation and skin allergy.

Contact dermatitis is not contagious or untreatable but can cause severe irritation and pain.

When the body comes in contact with some specific items, or substances or environmental changes, the body mistakes it as some kind of attack or foreign particle invasion and shields the body by developing antibodies in its response. In this confusion, it triggers a chain of bodily reactions which leads to the secretion of a chemical called histamine which in turn causes the allergic reactions.
