Eczema is due to a hypersensitivity reaction (similar to an allergy) in the skin, which leads to long-term inflammation. The inflammation causes the skin to become itchy and scaly. Long-term irritation and scratching can cause the skin to thicken and have a leather-like texture.
Eczema is most common in infants. The condition tends to run in families.
People with eczema often have a family history of allergic conditions such as asthma, hay fever, or eczema.
