In worse situations, they enter the bloodstream. The skin is the largest organ in the body. It is also the first line of defence against infection. The skin is made up of layers. They all have different functions. The epidermis is the first layer of the skin outside. It protects the body against different forms of parasites from the surrounding. The dermis is the next layer which provides nutrition for the epidermis. The subcutaneous tissue is the last layer which acts as a shock absorber for the skin, stores energy and regulates body temperature. Causes Of Skin Infection There are no parasites in the air but in the environment. There are no parasites on the skin. However, the skin is safe as long as the skin is not broken. Parasites can enter the skin from cuts or when there are allergic skin diseases su...
