In general, human skin is a very important part that surrounds the body and protects the body from the external environment and causes various immune activities. This skin is the largest organ of the human body, about 1.6 square meters in size, about 1.8 square meters in size, and about 16 percent in weight in weight, based on the average size of the skin.

One of these important organs, the skin cut vertically, is composed of three layers, the outermost epidermis, the middle dermis, and the deepest subcutaneous adipose tissue. , Hands / toenails, and tactile organs.

The epidermis is a very thin organ with no blood vessels, and the thickness of the epidermis is usually 0.07 to 1.12 mm. The thickness of the skin is determined not by the dermis but by the thickness of the epidermis. The epidermis is composed of five distinct cell layers, depending on the shape of the keratinocyte, although it depends on the thickness of the skin. The outer layer is composed of the stratum corneum, the transparent layer, the granular layer, the polar layer, and the basal layer. Also, in the epidermis, 28-day periodic keratinization occurs in which dead keratinocytes are detached and new cells are generated.

The stratum corneum is on the skin's most surface and forms a thin, dry thin skin. It consists of 50% protein called keratin or keratin, 20% fat, 23% water soluble substance and 7% moisture content. Moisture, etc., are combined with sebum, sweat, and the like secreted from the skin to form a skin barrier covering the epidermis.

Healthy skin has a pH of about 5.5 and is also called the acid mantle theory. Such an acidic protective film not only prevents a large amount of moisture from evaporating from the epidermis but also inhibits propagation of bacteria, bacteria and fungi, and protects the skin from dust, pollutants or harmful substances floating in the air .

In particular, the skin and hands are exposed to harsh environments compared to the skin of other parts of the body, so the incidence of skin disease is high. In addition, nails and toenails are formed on the hands and feet, respectively, and a great variety of abnormalities or diseases related to the nails and toenails are generated.
