Dryness of skin

One of the main types of skin - dry skin – proves feeling of tightening, a peeling, finely porous structure, a dim shade and easily arising irritation. If in youth dry face skin looks thin, velvety and gentle, then with age and without due leaving its state promptly worsens and leads to premature emergence of wrinkles and withering. Objectively the phenomenon of dryness of skin is characterized by violation of water and lipidic exchange, functioning of sweat and sebaceous glands, subacidic reaction of pH (an acid-base state). To define dry skin independently very easily: if when pressing on skin fingers traces long do not disappear, - means, your skin is dry and this information is intended especially for you.

Why to skin water

One of conditions of normal functioning of skin and its good appearance is the sufficient level of hydration (moistening). Moisture provides food of cells of skin, its elasticity and elasticity. Without due moistening skin becomes thin, dry, sensitive and wrinkled.

Dryness of skin is aggravated under the influence of many negative factors: cold weather and winds, dry air and sunshine, smoking and alcohol, the chlorinated and sea water, spirit lotions and alkaline soap, strong peelings and deficiency of vitamins A, E and Century.

Extent of moistening of skin is supported by two mechanisms of regulation providing moisture exchange with the environment: condition of a horn layer of epidermis and amount of skin fat. Horn cells of epidermis – korneotsita and the fat emitted by sebaceous glands form the lipidic layer protecting skin from dehydration (moisture loss).

This protective system not only supports moisture level in a term, but also interferes with penetration of the foreign agents causing hypersensitivity of skin. Not formation of a lipidic film opens a way to evaporation of moisture and, at the same time, reduces a protective barrier of skin, doing it vulnerable for penetration of toxins, allergens and pathogenic microbes. Thus, dry skin becomes subject not only to presenilation, but also emergence of inflammatory processes and immune reactions.

Violation of water balance of skin can be caused by a number of the reasons:

Reasons of dryness of skin

Specific features and age changes of an organism, the wrong care of face skin and bodies exert impact on work of the sebaceous glands providing protection of skin against moisture loss. Regulation of activity of sebaceous glands is carried out in the endocrine way, and in some cases can depend on influence of a hereditary factor. With age, the hormonal changes happening in an organism, cause decrease in activity of sebaceous glands and delay of production of skin fat. Many women, having passed a forty-year boundary, note the increased dryness of skin and mucous membranes. It is connected, first of all, with change of the hormonal status in the period of a menopause.

The defining factor of beauty, youth and health of skin the level of water balance of an organism is. Insufficient consumption of liquid with food can become the reason of dryness of skin. For maintenance of a condition of normal moisture content of skin cosmetologists advise to drink from 1,5 to 2 liters of water a day. Such volume of the used liquid not only makes up for its natural losses, but also brings toxins and products of disintegration out of an organism that, in turn, influences a condition of skin.

Dryness of skin, peeling and feeling of tightness are the reasons of early aging of skin. Loss of elasticity of skin leads to formation of a thin grid of small wrinkles which in lack of sufficient level of moisture content of skin quickly turn into deep grooves. First of all, wrinkles arise in corners of eyes and a mouth, and also on a neck – zones with the thinnest structure of skin. Adverse climatic factors (wind, low humidity, sunshine, cold air, differences of temperatures) dry up skin even more, deprive of it necessary moisture and protection.

To development of dryness of skin can give defective food, deficiency of vitamins and minerals, diseases of nervous system, work in hot shops. All these factors start the whole chain of the changes happening in skin. Decrease in protective barriers of skin causes moisture loss. In turn, it involves violation of processes of microblood circulation in fabrics and their traffic. As a result of insufficient food collagenic fibers suffer, elasticity and elasticity of skin decreases. These changes of skin are even more aggravated with lack of due leaving.

As the reason of dryness of skin wrong the choice of cosmetics and conditioning agents, and also holding some cosmetic procedures can also serve. During the insufficient work of sebaceous glands use of soap for washing, spirit lotions, the peeling peelings and srubs, the pulling together masks is contraindicated. From cosmetic procedures it is necessary to give preference to a fermental peeling most of which delicately affects a protective layer and intensively moistens dry skin.

The nutritious and vitaminized creams, the nutritious and toning masks, nonalcoholic tonics, creams with the content of collagen and elastin are necessary for dry skin. All these cosmetics will help to restore natural protection of skin. The used cosmetics has to be intended especially for dry skin and include the active complex moistening skin.

Important point of fight against dryness of skin is correction of food: an alcohol exception, enrichment of a diet the products containing vitamins A, E, C.

Methods of moistening of skin

Dry skin demands, first of all, sufficient moistening and protection against external irritants which are capable to do it harm. The moistening means for dry skin special substances – humektant (gidratant) providing the normal level of moisture without fail are included. On the mechanism of the action humektant happen film-forming and hygroscopic.

Mineral oils and fats belong to film-forming humektant glycerin, wax. Forming a waterproof film on the surface of skin, they promote deduction of moisture in skin and interfere with its evaporation. It is especially possible to distinguish glycerin from gidratant of this group – natural triatomic alcohol, hexatomic alcohol sorbite both linolenic and linoleic acids.

Thanks to the ability to hold liquid, glycerin many decades it is used in a compounding of cosmetics. Not so long ago American scientists opened one more property of glycerin – ability to give a signal and to stimulate process of maturing of young cells of skin. Cell renewal supports the normal level of moisture content and prevents dryness of skin.

The sorbite relating hexatomic alcohol to the same group, also has properties of hygroscopicity. It moistens skin, and also considerably improves texture of the moisturizing creams, masks and other cosmetic products, giving them plasticity, softness and velvet. Linolenic acid is capable not only to form a hydrophilic film on the surface of skin, but also to regulate barrier permeability of epidermis. Linoleic acid is necessary both for creation of a waterproof lipidic barrier, and for regulation of local immunity of skin.

The group of hygroscopic humektant includes urea, gialuronovy, pyrrolidonecarbonic and dairy acids, collagen. Molecules of these related to skin of substances connect water and hold it in skin. They are capable to restore in epidermis the level of a naturalnogouvlazhnyayushchy factor (natural moisturizing factor - NMF). Among this group hyaluronic acid which one gram transfers one liter of water to a gel state has the highest hygroscopicity. In the cosmetic industry the hyaluronic acid extracted their cock crests and leather of sharks is used.

The collagen (Greek - kleerodny) which is present at intercellular space and cells of skin is capable to absorb and hold the amount of water by 30 times exceeding its body weight. In the cosmetology industry ability of collagen to moisture absorption is widely used.

Choosing the moistening means for dry skin, pay attention to their structure and existence in them above the listed ingredients. The best way of fight against dryness of face skin and a body is development of the individual comprehensive program of moistening including councils for food and care of skin, the corresponding creams, masks and procedures. The problem of dryness of skin has to be solved by specialists dermatocosmetologists taking into account degree of dehydration of skin, seasonality, age and other specific features. Today it can be made with achievement of good cosmetic result, having prolonged youth and health to face skin and bodies.
