What is Skin?
Skin is a thin layer of tissue covering your body. It is the largest organ of your body that covers and protect the surface of your body. The skin has two main layers, called the Epidermis and the Dermis.
The Epidermis is the top or the outer layer of your skin. It helps to seal in moisture and protects your body from infections. It is made of several layers of living cells and topped by layers of dead cells. New cells are produced on its base, they quickly die and moved on the surface by the newly produced cells. These dead cells shed away giving you a chance fo a soft and glowing complexion. It holds your skin’s pigment, its thickness depends on the area. For example, your eyelids are thinner than the sole of your feet.
Tip: Drink a lot of water to maintain the smoothness and the plumpness of your skin of the dead cells.
The Dermis or Corium is the thick layer of living tissue below the Epidermis. it consists of bundles of strong fibers which give your skin its elasticity, firmness, and strength. It also contains blood vessels that feed vital nutrients to these areas. When the Dermis is damaged by injury it will be permanently damaged while the Epidermis is usually able to repair and restore itself good as new.
The Dermis contains the following organs:
Sebaceous Glands -It is a small gland in the skin which secretes a lubricating oily matter called the sebum into the hair follicles to lubricate the skin and the hair. The Sebaceous Glands are concentrated on the scalp and face, around the nose, cheeks chin and, forehead or also known as the T-zone, which is usually the oiliest areas.
Sweat Glands – The Sweat Glands or also known as Sudoriferous Glands these are tiny tubular structures of the skin that produce sweat. These are all over your body, their main function is to control and regulate your body’s temperature.
Hairs – It is a protein filament that grows from follicles found in the Dermis. Growing out your hair follicles, these help you to keep your body warm by trapping air underneath them.
