Eczema is a chronic skin condition characterized by dry, itchy, and red patches of skin. You may see the symptoms anywhere, including your face, elbows, and behind your knees. The diagnosis is often made in childhood, though it can affect people of all ages.
You'll likely notice your symptoms coming and going over time. A variety of triggers can cause your eczema to flare up, including stress and environmental factors.
Eczema is not contagious. However, there does appear to be a genetic component. If someone in your family has this condition, you are more likely to develop it.
