Contact dermatitis is a skin reaction when the body comes in contact with certain substances. There are two types of contact dermatitis: irritant and allergic. Irritant dermatitis involves contact with an irritating agent such as acids, conditioners, cleansers, detergents, hair dyes and some shampoos. Allergic dermatitis occurs when the immune system reacts to a specific substance, an allergen. Fabrics, latex, plants, pollen, some metals, ingredients in dermocosmetics, certain medicines can be considered as such.
More specifically, the clinical picture of eczema in the acute form includes erythema, blisters, swelling and itching. In the subacute form, it has all the above symptoms, but to a much lesser degree and intensity, while in the chronic form there is lichenification, itching and tightening of the folds (lines).
Eczema is not contagious. Its symptoms can be periods of remission and exacerbation.
The diagnosis for contact dermatitis is made by the competent doctor who is the dermatologist.
