Eczema is an inflammatory skin response. It is chronic and has flare-ups and remissions. It is not contagious. Some eczema may run in families with a history of allergies. There are various types of eczema: some caused by allergies or irritating chemicals, others the result of other medical conditions such as varicose veins. In the early states the condition is characterized by dry, red, itchy skin. An acute attack may produce crusty scales or blisters.

About 10% of Americans suffer from atopic eczema. In 70% of the sufferers the condition runs in the family. Symptoms may clear up after a week or two or may persist for years, resulting in a chronic condition. Treatment may also vary from person to person.
