Dry skin

Dry skin

xeroderma photo Dry skin is primarily expressed in violation of the water, as well as lipid metabolism, changing the operation of the sebaceous and sweat glands.In order to understand the causes of dry skin, we will look in more detail what is actually skin are and what their role in humans.

The skin is the outer layer that protects the body from external influences involved in thermoregulation, respiration and metabolic processes.The area of ​​the skin of an adult reaches two square meters, and weighs about one sixth of the total body weight.Skin act as a barrier between the human body and the environment, perform numerous important functions are involved in the regulation of body temperature, protect internal organs from various types of mechanical effects (pressure shocks, friction).

presence antiseptic environment on the skin protects the body against disease-causing microbes.Until then, until the skin is healthy, it supports the required level of moisture and protects a person from the influe

nce of sunlight.The negative impact of the environment, chemicals, cosmetics, ultraviolet irradiation, peridozirovka medications and nerve overload greatly upset the balance.As a consequence, there is peeling, redness, irritation, before the formation of wrinkles and dry skin.

The skin consists of three layers.First the epidermis, dermis, the second and third layer of subcutaneous fat.The epidermis is the outer layer reaches a thickness of 0.03-1 mm.Thinnest epidermis have eyelids, and in those places where a strong impact is most - epidermis thickens to 30 times.Epidermal desquamation of the upper layer is a normal physiological process, since the skin surface separates each day to two billion keratinized skin flakes.A cell epidermis updated every four weeks.Restoration of the skin is carried out by dividing the cells of the basal and the deepest layer of the epidermis.The basal layer of creatine in the synthesis of young cells.This is done at night.People do not notice the upgrade skin.The process of exfoliation is noticeable when the Department of dead skin cells are in large groups.The basal layer of the epidermis and plays an important role in determining our sun.It contains melanophores (pigment cells) involved in the formation of melanin pigment in the sun.Pigment cells are distributed on the skin surface uneven.For example, the face region has in each square centimeter is twice the melanophores than on the inner side of the arm.Therefore, the person is able to sunbathe a lot faster and stronger.If the skin is not able to produce melanin after sun exposure, this phenomenon is called albinism, but people relate to albino.

under the top layer of the epidermis is the dermis, which is much thicker (2.4 mm).The dermis is very dense, connective, fiber, fabric and a basic substance, comprising elastic and collagen fibers.These fibers are responsible for the condition of the skin and for whether the skin is dry, loose or stretched and taut.Collagen fibers under certain conditions absorb and store moisture.When filling with moisture to failure, skin visually look supple and smooth.The second important task is to ensure the dermis epidermis nutrients: trace elements, vitamins, oxygen, proteins, minerals and amino acids.The dermis is able to maintain a constant body temperature in the range of 37 degrees.Temperature control is carried out automatically.Blood, tiny capillaries in the narrow sense of the cold and the heat expanding.When the narrowing of blood vessels visible on the surface of the skin, she is given the name of "goose".If the body overheats or is working hard physically active sweat glands secrete sweat.Speaking at the surface of the skin, the sweat evaporates.Thus, there is a cooling of the skin and protect the entire body from overheating.

last speaker subcutaneous fat, which is the deepest layer of skin.It is able to reach a thickness of a millimeter to several centimeters.The composition of the fiber includes a loose connective tissue is deposited in the first place on the abdomen, buttocks, thighs.Subcutaneous adipose tissue acts as protection against impact, the energy "depot" and termoprosloykoy.The thickness of the layer of fat is directly dependent on nutrition, age, sports load, the hormonal system, heredity.The fabric has a fiber nerve endings, as well as the roots of the hair.

So, we understand that the skin is one of the great human body organs to perform numerous and diverse functions.The appearance of the outer cover just said about the state of the whole organism.

But that signals a dry skin and what is dangerous, we'll try to understand.Dry skin or dry skin (xeroderma) is one of the signs of lack of moisture in the top layer - the epidermis.The epidermis accumulates a small amount of water (up to 20%).At the first sign of lack of moisture, the following occurs: the lower layers of the skin intensively evaporate water, and marked slowdown in the metabolic processes that lead to their tarnishing.
