The difference between allergic and irritant contact dermatitis

There are two types of reactions: allergic contact dermatitis and irritant contact dermatitis. Consult with your dermatologist to determine if your dermatitis is allergy or irritant related.

What is allergic contact dermatitis?

Allergic contact dermatitis is the mechanism (immune system) that protects the body from chemical substances on the skin overreacts and causes damage to the body. Reactions begin with itching and can be followed by redness, swelling, or bumps. Once you become allergic to a substance, you will experience reactions every time your body comes into contact with that substance for the rest of your life.

What is irritant contact dermatitis?

Irritant contact dermatitis is a reaction such as redness and pain that occurs due to chemical substances on the skin when the skin is sensitive or the skin is damaged and the barrier function of the skin is weakened. You may or may not experience reactions when coming into contact with the same substance depending on the condition of your skin.
