Atopic dermatitis is the most common form of eczema; it is likely genetic, though the exact cause is unclear. It may be caused by a breakdown of the skin’s barrier cells or by immune dysfunction resulting in IgE sensitization. The rash of atopic dermatitis is often red and itchy and usually presents for the first time during childhood. Around 10 to 12% of children and almost 1% of adults in the United States have atopic dermatitis. Atopic dermatitis is often seen in people with asthma and allergies. There are multiple treatment options available including moisturizers, topical steroids, topical immunomodulators, barrier repair creams, antihistamines and UV therapy.
