Atopic dermatitis (eczema) is an itchy inflammation of your skin. It’s a long-lasting (chronic) condition that may be accompanied by asthma or hay fever. Eczema is most often seen in infants and children, but it can continue into adulthood or first appear later in life.
Eczema may affect any area, but it classically appears on your arms and behind the knees. It tends to flare periodically and then subside. The cause of atopic dermatitis, or eczema, is unknown, but it may result from a malfunction in the body’s immune system.
Self-care measures, such as avoiding soaps or other irritants and applying creams or ointments, can help relieve itching. See your doctor if your symptoms distract you from your daily routines or prevent you from sleeping.
