Skin care
The skin is a protective covering of the body. It, with all its specialized derivatives, makes up what is called the integument (Latin: a covering) which covers the entire surface of the human body. The human skin shows wide regional variations in structure like scalp, face, ear lobes, back, palms and soles etc. Thickness varies; the number of sebaceous glands, collagen fiber and vasculature differ in different parts of the integument.
Anatomy of Skin
The skin is composed of a superficial epithelial layer- the EPIDERMIS, and an underlying connective tissue layer, the DERMIS or CORIUM. Beneath the corium is another connective tissue layer, rather loose in texture-the HYPODERMIS, or subcutaneous layer.
The free surface of the epidermis is marked by a network of linear furrows and ridges of variable sizes. On the fingers, these have a constant pattern differing in each individual; a person, therefore, can be identified by his fingerprints (dermatoglyphics).
Function of the Skin
The skin performs a multitude of functions. These are:
1. Protection - Self and body
2. Sense organ
3. Secretion and excretion
4. Body temperature regulation
5. Storage of fat, blood
6. Absorption
7. Gaseous exchange.
