The structure of the skin

It is said that skin is the mirror of the soul, so that the beauty of the skin has a direct bearing on the welfare and human health. The skin is our largest organ and is equal to 16% of body weight. One can consider the skin as a barrier between the physical body and the environment.

The three layers of the skin

The skin is composed of three layers, each of which has its own role and objectives. These layers are the epidermis or outer layer, the dermis and lower dermis or subcutaneous layer. Let's look at each in detail:

Subcutaneous layer: this layer performs the functions of food, caloric and exchange. It is the "Metabolic Zone" where are the sweat glands, fat tissue, hair bulbs (site of an intensive proliferation) and a thin muscle, which when contracts is known as "goose bumps". Sweat glands excrete not only products through transpiration, but also control the temperature by evaporation on the skin surface.

Dermis: is a layer of connective tissue, which contains many fine blood vessels, the capillaries, allowing skin to breathe and the food of the outer layers. The dermis is the layer that absorbs the substances that are applied on the skin. Here are the sebaceous glands at the base of each hair follicle, secreting the oily material called sebum that keeps the skin lubricated. So that the skin is a good balance, it is essential having normal functioning of the sebaceous glands. The joint action of both provides the "acid mantle", a natural film that protects skin against external attacks. The over-activity of the sebaceous glands, as in adolescence may lead to the formation of black spots and pimples.

Skin: is the transparent outer layer that covers the entire exterior of our body. Here we have many nerve endings that make the skin an extensive sensory organ, which detect heat, cold, light, taste and touch. Through these nerve endings, we can experience pleasure and pain, and emotional changes can be observed from pale to blush.

Its role protecting is continually exposed to external aggression, which is kept by the eternal renewal of the inside out. This implies an enormous scaling of dead cells, which in the course of a lifetime is about 20 kg. This is structuring itself a Neuro-sensory pole. It is worth recalling that this action is closely linked with silica and products containing plants rich in it, as act on that pole.

This is good information about the skin, because many of us just take care of it without realizing the importance of all its parts, and all of them require the proper care I imagine, so I think it is important to keep in mind that this is one of the biggest and greatest organs we could get
