Atopic dermatitis (eczema) is a condition that makes your skin red and itchy. It’s common in children but can occur at any age. Atopic dermatitis is long lasting (chronic) and tends to flare periodically. It may be accompanied by asthma or hay fever. No cure has been found for atopic dermatitis. Certain substances or conditions called trigger factors can cause eczema to flare (ie: become worse). These trigger factors can be: Irritants such as soaps and detergents, wool, skin infections, dry skin, low humidity, heat, sweating or emotional stress allergens such as dust mites, pollen, molds or foods.
