What causes contact dermatitis?

Irritant contact dermatitis is caused by particularly acidic or alkaline substances, such as detergents, soaps, perfumes, preservatives and chemicals. These substances damage the outer layer of skin, leading to inflammation. In allergic contact dermatitis, inflammation occurs when an allergic response causes the immune system to attack healthy cells. Some common causes include nickel, cosmetics, rubber, adhesives and certain medications.
