Xeroderma
Description:
The xeroderma is a complex of symptoms which develop owing to decrease in moisture content in the most upper layer of epidermis – a corneous layer.
Xeroderma symptoms:
There are two kinds of dry skin:
- dry skin with a good tone. The surface of such skin opaque, smooth, without wrinkles, elastic. It is usually characteristic of young age, however it is very sensitive to any irritants. Demands permanent cosmetic care, protection against the sun and external influences. In the absence of due leaving quickly loses a tone
- dry skin with a reduced tone. Skin is thinned, especially in eyes and around a mouth, constant folds and wrinkles quickly form. Usual cosmetic leaving can affect only partially a condition of skin, in this case more effective and modern techniques are required.
At insufficient department of skin fat, skin becomes dry, rough, is shelled, its elasticity disappears. Often occurs at blondes at whom thin and gentle skin easily inflames from influences of external environment.
Dry skin is pulled together when wash in its evening. In extreme cases it becomes pergamentoobrazny or sluggish. On dry, sluggish skin thin wrinkles at first on each side of cheeks, then under a chin and on a decollete appear.
Dry skin with the lowered sebaceous secretion looks thin, does not shine, easily and often inflames.
Doctors usually define a condition of a xeroderma as "xerosis". The concept of "xerosis" includes not only сухость skin per se, but also those symptoms which can accompany it, in that чис le an inflammation, an itch and burning. About 20 years ago with changes in air conditioning systems in rooms learned about a xerosis around the world as the number of the people suffering from this problem sharply increased.
The xerosis or the raised xeroderma happens physiological - at babies is after the birth. Spontaneously in a month it passes, however from 6-month age, dryness arises again as secretion of skin fat at babies decreases. Especially it becomes aggravated in the cold and dry winter. This problem is known as "a winter itch".
The xerosis strikes elderly people at whom at the same time with decrease in metayobolichesky activity of skin activity of sebaceous glands, especially on the lower half of a body decreases.
Xerosis - a problem of exclusively upper layer of skin, corneous layer. It loses ability to hold water. Water from skin cells quickly evaporates to the environment. The balance is broken. The organism gives more water, than can compensate for more deeply the lying skin fabrics. The upper corneous layer does not spravyolyatsya with a problem of protection and allocation. The urgent help is necessary for it.
Xeroderma reasons:
- Dehydration
- Chronic intoxication
- Dystrophies
- Hypovitaminosis of A and PP
- Ichthyosis
- Hypothyroidism
- Disbolism
- Disturbance of functions of digestive tract
- Stress
- Atopic dermatitis
- Renal failure
- Diabetes
- Allergic rhinitis
Treatment of the Xeroderma:
For the purpose of protection of skin from drying and damages the daily leaving directed to clarification, dryness reduction, moistening and protection against adverse environmental factors, elimination of an inflammation and subjective feelings of an itch, pain and burning is necessary.
For achievement of these properties use numerous components of various origin. Conditionally they are subdivided on:
• occlusive substances which provide bystry creation of a waterproof film on the surface of skin, but do not remove the cause of her dehydration and block signals for activation of biosynthesis of lipids (vaseline, silicone, saturated fats);
• not occlusive substances containing hydroscopic molecules (glycerin, sorbitol, hyaluronic acid, proteinaceous hydrolyzates – collagen, wheat protein, vegetable polysaccharides – chitosan, b-glucan, components of the natural moistening factor (NMF) – lactic acid, urea, a pyroglutamate of sodium, amino acid – serine, glycine, alanine, proline, etc.);
• the film-forming substances providing mechanical protection against influence of the toxic and irritating substances (chitosan, b-glucan, hyaluronic acid);
• the antioxidants providing protection against peroxide oxidation (vitamin E, vitamin C, fermental antioxidant of superoxide dismutase, bioflavonoids);
• the substances providing skin food (irreplaceable fatty acids, vitamin F, borago oil, evening primrose oil, oil of seeds of blackcurrant, linseed oil, fish oil).
For recovery of an epidermal barrier use of the tseramidsoderzhashchy moistening means is very effective. Ceramides are the physiological lipids making a natural lipidic barrier of a corneous layer of skin and preventing transepidermal loss of water.
