Types of skin and skin hydration

The skin is our outermost layer, our wrapper. It protects us and separates us from the outside, yet allows the communication, interaction and perception. Its main function is to prevent the entry of pathogens, regulate body temperature and keep hydrated. Layers of the skin

It is divided into three layers are the epidermis, dermis and hypodermis (the innermost of all). In the epidermis are keratinocytes, cells that are born at the base of the epidermis and as they develop, move towards the surface where they die and form the stratum corneum, lipid-rich at the same time, does not allow bacterial growth and prevents the exit of the water out, or maintaining skin hydration. If any injury or allergen reaches the epidermis, this will be also responsible for causing a signal to the immune system. In the dermis are collagen fibers that are renewed at a slower rate than keratinocytes. This layer is responsible for providing elasticity and firmness. Finally, the hypodermis is the innermost layer of the skin produnda she resides in adipocytes, fat cells formed and basically provide a buffer against physical damage, reserve power and temperature control.

SKIN TYPES

Many times when we wonder about your skin type can have doubts about this, since there are many factors that change over time (age, disease, acne, geography, lifestyle, etc ...). In summary, there are 4 types of leather that broadly define briefly: Normal Skin: The person has no visible injuries, no feeling of disgust. Is uniform and no problems alérgico.Piel Fat type: A type of skin that is established at puberty, when androgen levels increase the production of sebaceous glands and consequently there is more fat in the skin. The skin becomes thick, bright points are visible sabáceos follicles are dilatados.Piel Seca: The skin is not uniform. There are areas with cracked and peeling. In addition, the skin is tight even to produce an unpleasant sensation in the persona.Piel Mixed: A combination skin type oily skin with dry skin. In other words, areas with greater presence of fats and other, for example, are cracked. Does having dry skin is synonymous with water that I'm missing? This is undoubtedly one of the first questions that people do.

In many cases, the water in the skin is not retained and "escape" because they fail the structures that maintain hydration. Hydration Matiena What then?

Dermatology is known in two main structures such as the Natural Moisturizing Factor (NMF) which is composed of protein, urea, lactate, uric acid, ammonia, sugars and other organic acids that are responsible for retaining water in the dead keratinocytes . Today, hyaluronic acid also plays an important role in the capture of water into the cells. The lipids of the keratinocytes go abroad when they die and are responsible for the other structure, an impermeable layer composed of fatty acids, cholesterol and ceramides to prevent the passage of water through the cells.
