Eczema (atopic dermatitis) is a common chronic skin condition that is characterised by areas of skin becoming red, dry, and itchy and in severe cases, skin may weep or bleed. Eczema is not contagious and usually appears in early childhood. The condition is hereditary, and sufferers are more likely to also suffer from hay fever, asthma, and allergies.

Although flare-ups can often appear to occur at random, they can usually be narrowed down to several internal and external triggers. Internal triggers include family medical history, food and alcohol sensitivities and stress. External triggers include irritants such as chemicals (detergent, soap, perfume, shampoo), weather (hot and humid conditions or dry and cold conditions), and allergens such as pollens, pet hair, dust mites, clothing, and grass.
