Is eczema hereditary?

Sometimes. Eczema is in the same group of conditions as allergies and asthma, and can run in families the way they do. It can occur without a family history, though. Also, similar rashes can be caused by contact with irritants or certain metals if you're allergic to them. Use sensitive skin cleanser, avoid bathing in very hot water, and use sensitive skin lotion at least 3 times daily.See your doc if you need.
