Actually Skin

The skin itself is one of the main layers of the skin, also known as the dermis. The dermis is the second layer of skin, located below the epidermis, and makes up approximately 90% of the skin's thickness. It plays an important role in protecting the body, regulating body temperature, perceiving tactile sensations and many other physiological functions.

The dermis consists of two layers: the upper papillary and the lower reticular. The top layer contains many small projections called papillae, which increase the contact area between the dermis and epidermis. This allows the epidermis to receive more nutrients and oxygen from the blood vessels of the dermis. The bottom layer contains a dense network of collagen and elastin fibers, which provide strength and elasticity to the skin.

In addition, the dermis contains many other important components, such as fibroblasts, macrophages, lymphocytes and other cells of the immune system, which play an important role in protecting the body from infections and other external influences.

One of the main functions of the dermis is the regulation of body temperature. The dermis contains many blood vessels that can expand and contract depending on environmental temperature and body activity. This allows you to regulate the flow of blood and heat, maintaining an optimal body temperature.

In addition, the dermis contains many nerve endings that provide the perception of tactile sensations. This allows a person to feel different textures and surfaces, as well as feel pain, pressure and other tactile stimuli.

Overall, the dermis is an important component of the skin, playing a critical role in protecting the body, regulating body temperature, and sensing tactile sensations. Therefore, in order to maintain skin health, it is necessary to pay sufficient attention to the care of the dermis and provide it with all the necessary nutrients and care.
