Contact Dermatitis Types

  • Allergic Contact Dermatitis

This condition is a result of an immune reaction in your skin when it comes in contact with allergens or substances to which you are sensitive. Your immune system releases white blood cells into the skin that releases chemical mediators of inflammation. This causes an itchy rash that may take several minutes, hours or days to develop. 

Allergens such as metals in jewelry, cosmetics, and fragrances affect only the area of your body they come in contact with. However, certain allergic substances that enter your body through foods and medicines can also trigger a reaction.

  • Irritant Contact Dermatitis

This is a condition that is more common than allergic contact dermatitis. This skin reaction occurs when the outer layers of your skin come in contact with a chemical substance or toxic material. It develops a rash, which is more painful than itchy. 

Your skin may even react to strong irritants in a single exposure. Sometimes, symptoms may develop after repeated exposures to strong or mild irritants. In some cases, people develop a tolerance to certain irritant substances over time.
