Causes of Eczema
Differences in the skin of people with eczema may contribute to the symptoms of the disease. The epidermis, which is the outermost layer of skin, is divided into two parts: the inner part, which contains moist, living cells; and the outer part, which consists of dry, flattened, dead cells. Under normal conditions, the outer layer of skin acts as a barrier, keeping the rest of the skin from drying out and protecting other layers of skin from damage caused by irritants and infections. When this barrier is damaged or is naturally thin, irritants act more intensely on the skin.
The skin of a person with eczema loses too much moisture from the epidermal layer. This allows the skin to become very dry, which reduces its protective abilities. In addition, the skin is very susceptible to recurring disorders, such as staphylococcal and streptococcal bacterial skin infections, warts, herpes simplex, and molluscum contagiosum (which is caused by a virus).
