Eczema or contact dermatitis is a skin disorder characterized by itching,
scaling, thickening of the skin, usually located on the face, elbows, knees, and
arms. The exact causes are still unknown, but an abnormal function of the immune
system is believed to be a factor. There are several types of eczema, which can
be triggered by various chemicals, environmental agents or psychological
factors. Treatment is to keep the skin well hydrated.
