 One of the most popular ingredients in cosmetics for skin care - hyaluronic acid. This name can be found on almost every second jar with cream. What is this wonderful universal component which copes with a variety of skin problems?
Born to be a
Hyaluronic acid
- A rare type of substances whose molecules are the same for all living organisms and humans, and microbes. In the body, it performs a variety of functions, such as maintaining normal hydration of the epidermis and deeper layers of the skin. It is a kind of biological "cement" that binds the fibers of collagen and elastin of his predecessor in the skin. In cosmetics, hyaluronic acid and its sodium salt (sodium hyaluronate) are used as superficial and deep intense moisturizers. Pure hyaluronic acid helps fight the signs of aging skin.
Hyaluronic acid is found in almost every tissue of the human body, "stitching" of the cell and strengthening the relationship between them. The protective function of the cells with the increase, it is not only the mechanical protection of the cells, but also the microbiological barrier. This substance is essential as a component of synovial fluid. As part of the vitreous body, it promotes the normalization of intraocular pressure. Great biological importance as well as participant in the process of fertilization.
The contents in the body's own hyaluronic acid depend on many factors.
Like all other processes in the human body, the content of hyaluronic acid in the tissue is regulated by hormones. Of great importance is entering from the outside certain vitamins and minerals, such as magnesium, iron, zinc, ascorbic acid. With a lack or excess of these substances the formation of hyaluronic acid decreases, worsening its "quality".
Lack of hyaluronic acid is considered one of the main factors of the aging of the whole organism
in general, and its characteristics such as the decrease in the mobility of joints, changes in skin appearance, various diseases of the cardiovascular system and of age-related changes.
Water, water, water everywhere!
Our skin is 70% of the water, which is about 15% of the water contained in the body! The amount of water in the body depends on the age and genetic predisposition human.
It is hyaluronic acid, a substance like no other, is responsible for maintaining moisture in the skin.
Together with its "working" and some other substances, such as urea, lactic acid, collagen. The complex molecules such busy absorption and retention of moisture from the outside and from the inside - this is the most natural moisturizing factor, or NMF (natural moisturizing factor). With age, the skin's moisture balance, inner and outer, is broken, reduced production of hyaluronic acid and is accelerating its destruction. The consequence of these processes is the deterioration of the appearance of the skin, dehydration and wrinkles, both surface and mimic.
The main unique characteristic of hyaluronic acid - binding capacity 10,000 times with the amount of water!
Even one percent acid solution has a high viscosity. The solution is this concentration is a natural stabilizer of the gel in the vitreous eye to ensure his physical structure.
Hyaluronic acid molecules are very large and because it is unable to penetrate the skin surface, it acts as a protective film, which supplies moisture epidermis. But the low molecular weight hyaluronic acid (split into smaller pieces) has a smaller molecular size, so penetrate into the deeper layers of the skin and stimulates the synthesis of collagen and elastin, strengthening intercellular connections. Because of this "internal stimulator" it is introduced into the reducing, wound healing, anti-aging creams.
With constant use of creams with this ingredient gets rid of dehydrated skin becomes soft, supple, surface wrinkles smoothed. Hyaluronic acid - a natural component of human skin, forming a normal water balance on the surface of the skin and inside. It is perfectly compatible with the skin, as with proper cosmetics allergic reactions are extremely rare.
The natural source of beauty ... in the same syringe
The gels of hyaluronic acid (with large and small molecules) are used for correcting the shape of the lips, the alignment of facial wrinkles around the eye, glabellar and nasolabial folds, and for correcting existing scars. Such correction without aggressive intervention will eliminate these shortcomings without plastic surgeon.
In cosmetology applied hyaluronic acid of animal origin, for example from cocks' combs, vitreous body of cattle eyes, and microbial origin - it is produced bacteria of the genus
Streptococcus
. Most important in the process of obtaining the drug is purified and stabilized hyaluronic acid, that it is resistant to destructive factors, namely enzymes. Microbial hyaluronic acid is preferable to use, as it does not cause allergic reactions in people who have a tendency to such displays using means of animal origin.
Hyaluronic acids of different molecular weight are used various kinds of gels for administration to the skin, for example, drugs
Restylane®, Perlane®, Juvederm®, Rofilan Hylan®, AcHyal®
. Materials based on this substance have been used successfully to increase the volume of the lips, the cheeks, the cheeks, chin, nasolabial folds and filling folds in the corners of the mouth, outline correction, size and shape of the lips, smoothing the skin above the upper lip. The procedure takes no more than 30-40 minutes. During the procedure, the smallest portion of the gel injected under the skin very thin needle. Gel particles are naturally incorporated into the surrounding tissue and do not hinder free movement of hormones, oxygen and other vital substances. The effect of the procedure lasts from 6 months to a year, depending on individual circumstances. Hyaluronic acid is introduced into the body over time dissolves, then absorbed by the body and completely removed from it without causing any inconvenience.
The ability to use hyaluronic acid for cosmetic purposes - one of the most successful scientific discoveries help to preserve youthfulness.
In addition, this substance is used in many areas of medicine - cardiology, trauma, surgery, dermatology, being a part of medicinal products for indoor and outdoor use.
