Dermatitis is a skin disease that results in the inflammation of the skin. The skin rash may be mild, moderate or severe and is caused by infections, allergies and other triggering factors. The skin may become red, itchy and swollen. Some of the common types of dermatitis include atopic dermatitis, contact dermatitis and seborrheic dermatitis.
Dermatitis may be genetically inherited. This skin condition is not contagious and therefore may resolve quickly. In some cases, depending on the season, environmental exposure and stress, it may last for a longtime. Dermatitis can be treated with self care steps, medications and phototherapy.
