DISCOVERY OF THE SKIN
With a surface area of nearly 2sqm, this living envelope is a flexible, resistant, stretchable and waterproof fabric that is constantly renewed and protects us from UV rays, microorganisms but also shocks. Its two million pores contribute to the regulation of body temperature by the retention or elimination of water.
It is therefore essential to take care of and preserve it.
The cutaneous structure is composed of three successive layers: the epidermis, the dermis and the hypodermis. There are also hair follicles (hairs) corresponding to an invagination of the epidermis, which continue at the level of the deep dermis and are accompanied by the sebaceous glands that secrete the sebum. The latter is essential for the lubrication of the skin and its protection against many bacteria. The sweat glands also represent invaginations in the epidermis and dermis. The skin thus has its flexibility and its resistance to the tissue layers which constitute it.
