What’s Skin and How Does It Operate? Believe it or not our skin is our bodys biggest organ which covers each and every surface of the body. It’s possible for each girl to have perfect skin no matter race, age or colouring, provided that she understands how it works and how to care for it. This is the upper layer of skin that you may see. Its role is to defend the body from disease and seal in moisture.
Layers
It’s composed of several layers of living cells that are then composed by sheets of dead cells. The skin is continually growing and producing new cells in the base. The dead cells eventually flake out, thus meaning that each and every time a fresh layer of skin forms, this is the opportunity to have a soft, luminous complexion. The lower levels of skin cells are fed by the blood supply from beneath, whereas the top dead cells need only water to be sure they are kept smooth and plump.
The epidermis is liable for your skin as it retains the skins pigment. The thickness of your skin changes, and is significantly thinner around the eye area. The dermis is the layer which lies beneath the skin, and consists of living cells only. It is composed of bundles of tough fibers that give elasticity, strength and stability. Additionally, there are blood vessels that feed vital nutrients to those areas. Unlike the epidermis which could repair itself, the dermis, if wounded will be permanently damaged.
Sebaceous Glands
These are tiny organs which opens to hair follicles on the surface of the skin. They create your skins natural lubricant, an oily secretion called sebum. These glands are largely concentrated on your face and scalp, especially around the nose, cheeks, forehead and chin. This explains why these regions are wider than many others.
Sweat Glands are found throughout your body and they help to regulate your bodys temperature The temperature of your skin falls as the sweat evaporates on the skins surface.
