Eczema is a non-contagious, chronic, inflammatory skin disease that most often appears in childhood. The skin becomes scaly and itchy with blisters that contain fluids; the skin can weep as well. Weeping is the main symptom of an infection.
When the body cannot repair damaged skin, a person suffers eczema. It is caused by a mutation in a gene called Filaggrin that is responsible for the formation of the skin barrier. In a healthy body, every cell has two copies of the gene. But in people with eczema, there is only one copy of Filaggrin. Thus, their skin can't properly repair itself.
Environmental allergens can disrupt the skin barrier and produce inflammation that makes the skin itchy and dry. Eczema varies in severity, and the symptoms are different, as well. There is still no way to prevent eczema, but there are treatments that can significantly reduce its symptoms. If your condition becomes worse, you should see a doctor.
