The skin is our outer 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 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, moving towards the surface where they die and form the stratum corneum, and rich in fat at the same time, does not allow prevents bacterial growth comes out of the water out, or maintaining skin hydration. If any injury or allergen reaches the skin, 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 is the layer responsible for providing elasticity and firmness of the skin. Finally, the hypodermis is the innermost layer of the skin produnda live there adipocytes, primarily by fat cells formed and serve as a buffer against physical damage, reserve power and temperature control. TYPES OF SKIN Many times, when they ask us about our skin type can have doubts about it, because there are many factors that make change over time (age, disease, acne, geography, lifestyle, etc) . In summary, there are four skin types that broadly define briefly: Normal Skin: The person has no visible injuries, no feeling of discomfort. Is uniform and no allergic problems. Oily skin is 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 sabaceos follicles are dilated. Dry Skin: The skin is not uniform.

There are cracked and scaly areas. In addition, the skin is tight even producing an unpleasant sensation in the person. Combination Skin: This is a combination skin type oily skin with dry skin. In other words, there are areas with a greater presence of fats and other, for example, are cracked. Does having dry skin is synonymous with water I need? 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? In Dermatology there are two major structures such as the Natural Moisturizing Factor (NMF) which is composed of proteins, urea, lactate, uric acid, ammonia, sugars and other organic acids which 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 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.
