The part of the skin referred to as the dermis is sandwiched on top of the hypodermis and under the epidermis (the outermost part of the skin) and is a vitally important area of the skin, since it is here where the fibroblast cells form the network of fibers of the skin - very much resembling the weft and warp of fabric - and for this reason it is also referred to as the connective tissue.
The connective tissue is mainly made-up of collagen and to a far lesser degree elastin.
Collagen and elastin are complex proteins responsible for the support and elasticity of the skin and enables the skin to regain its shape after being pulled, stretched or pushed.
This area of the skin is fed by blood circulating through tiny arteries, veins and capillaries, to bring nutrition and oxygen to the cells, whilst removing waste products.
Each square inch of the dermis contains about 15 feet of small nutrient providing vessels.
Although they provide nutrition to the skin and remove waste material, their constriction and dilation is of vital importance to keep our body temperature constant.
The dermis also contains the sensitive nerve endings, sweat glands, hair follicles and sebaceous glands.
