accommodating longer hair. The skin’s surface isn’t made up of just a single stratum. It’s two defined layers the epidermis and the dermis. The epidermis, also known as scarf skin or cuticle is a thin layer of the skin and forms a protective covering for the inner layer containing no blood vessel, but it has numerous little nerve endings. The epidermis is made up with the following layers:

The horny layer or outer layer of skin

The outer layer of skin consists of scale-like cells being shed and replaced by underneath cells and consists of the protein keratin plus a covering of oil.

The clear layer of skin

This skin layer is made of small transparent cells capable passing light rays.

The granular layers of skin

The granular layer is made of cells, which appear like distinct granules.

The thick layer of skin

The thick layer composed of a number of layers of various shaped cells. The deepest layer consists of a dark skin pigment known as melanin and is accountable for the development of the epidermis. The melanin shields the cells from the destructive outcomes with the ultra-violet rays of the sun.

The inner layer of the skin

The Dermis, the inner layer of the skin, can also be known as derma, cerium, true skin or cutis. The dermis is highly delicate and is really a vascular layer of connective tissues containing blood vessel, lymph vessels, nerves, sweat glands, oil glands, hair follicles and muscles. The dermis, 25 times thicker than the epidermis is highly sensitive. It is made of two layers the papillary or superficial layer and reticular or deeper layer.

The skin receives its nourishment from the blood and lymph. In between half and two thirds of the total blood supply of the body is distributed towards the skin, which consists of several capillaries. The blood and the lymph circulating via the skin contribute to its development and nourishment.

Cleanliness keeps the skin free of charge from blemishes. Skin consists of two kinds of duct glands, which extract materials from your blood. Sweat glands secrete sweat whereas sebaceous oil glands secrete sebum. Sebum is a semi-fluid oily substance flowing via the oil ducts; when the sebum becomes hardened, the ducts are blocked forming a blackhead.

Nerves with the Skin

The skin consists of numerous nerve fibers, which supply the body using the sense of contact, discomfort, heat, cold, pressure or deep contact. The pliability of the skin is dependent on the elasticity of the dermis and a healthy skin regains the former shape instantly. Aging skin is triggered as a result of skin’s loss of elasticity. The color of the skin whether fair, medium or dark is dependent on the blood supply towards the skin and primarily, on melanin. The color of the skin varies from person to person. Melanin shields delicate cells from sunburn and tanning by ultra violet rays.
