Is characterised by patches of dry, red, flaking skin and areas that become inflamed, moist and oozing.
The name is taken from the Greek word ‘to boil over’. It is an inflammation of the epidermis (one of the layers of the skin) and is a form of dermatitis. In England, an estimated 5.7 million or about one in every nine people have been diagnosed with the disease by a clinician at some point in their lives.
The condition may affect any part of the body, but is typically found on the face, scalp, behind the ears, in the creases of the elbow, knees and groin. Some people only have it for a short period of time, whilst others get it persistently throughout their lives. It is not contagious.
