Eczema is a skin disease. The first sign of eczema tends to be patches of dry or red, itchy skin. Scratching the skin damages its surface and can worsen the rash.
Sometimes, eczema is called atopic dermatitis. It usually beings very early in life. It is common in infants and young children, and most people who get eczema will have it before they turn five years old. It is rare for eczema to appear for the first time as an adult.
Eczema tends to come and go, often without warning. A treatment plan that includes skin care can reduce flare-ups and ease much of the discomfort.
