What Is Atopic Dermatitis?

Atopic dermatitis (eczema) causes chronic skin irritation. This condition can affect people of all ages. It often runs in families (is genetic). It may also be linked to allergies such as hay fever and sometimes asthma. Patches of skin become dry, red, itchy, and scaly. In people with abnormally dry skin it's often called xerosis. Sometimes atopic dermatitis is only on the hands or feet. It often improves when the skin is well hydrated. It gets worse when the skin is dry. You can help control symptoms by practicing good self-care. Stay away from anything that causes flare-ups such as sunburn or vigorous scratching.

Where do you have symptoms?

Atopic dermatitis symptoms can appear anywhere on the body. But in most cases, they vary based on the person’s age. In babies, irritation is often seen on the scalp, cheeks, chin, near the mouth, and under the eyelids. In children ages 2 through 10, skin folds such as the backs of the knees or in the arm crease are most often affected. In children 11 and older and in adults, symptoms can affect many areas.

What triggers symptoms?

Symptoms flare because of many things. These include skin dryness, scratching, stress, harsh soaps, and irritants such as dust or wool. Try to stay away from anything that causes flare-ups.

Recognizing what causes flare-ups

The things that affect each person vary. So keep your own list and try to stay away from your triggers.
