Eczema (also known as atopic dermatitis) is a prevalent, rash-like, itchy skin condition that children often develop by the age of five. Simply put, eczema is a condition that causes a person's skin to become red and itchy. It may start as a simple rash, but the skin becomes inflamed and even redder when scratched. Eczema can show symptoms anywhere on the body. Although there is no known cure for eczema, early diagnosis, lifestyle changes and treatment can significantly reduce symptoms.
