Eczema is related to a gene variation that affects the skin’s ability to function in this protective manner is compromised; this allows the skin to be affected by various environmental factors, irritants and allergens.4c

Eczema is thought to be caused by a “leaky” skin barrier. This means water escapes leaving the skin dry. Some people have this leaky skin gene passed down from parents or it is driven by factors in the environment.2h
