In the modern cosmetology Hyaluronic Acid is a highly demanded substance, which is used for supporting youth, health and beauty of face skin. Being one of the most powerful skin moisturizers, Hyaluronic Acid is included into the vast majority of rejuvenating cosmetic products and procedures.

 

How does Hyaluronic Acid work?

Skin contains up to 15% of all liquid in body. The substance responsible for the liquid balance and its restoring is Hyaluronic Acid, which molecule is a one of structural components of dermal tissue. Besides moisturizing, Hyaluronic Acid connects and supports collagen and elastin fibers, that provide skin tone and healthy appearance.

Over time fibroblasts, that synthesize Hyaluronic Acid, reduce their activity and the quantity of HA in skin is getting lower. The scientists discovered that middle-aged people lose about 3% of this valuable component a year, so humidifying skin loses firm, elasticity, become flaccid. The face contour may become deformed, wrinkles and fine lines appear. It is important to note, that HA reducing is not related only aging, but harm of UV-radiation, lack of vitamins C and E, magnesium, zinc, iron.

How to replenish the shortage of Hyaluronic Acid

Hyaluronic acid is created in labs by chemical and bioengineering methods for medical and cosmetic purposes and is included to the variety of cosmetic and medical products. Skin reacts positively on a HA replenishment, so continuous use of Hyaluronic acid cosmetics is enough to support the needed liquid balance. Having got into a skin depth, HA binds water and increase moisture, lifts skin, smoothens small wrinkles. For the deep aging signs reducing certain cosmetical procedures with HA can be indicated: mesotherapy, contour correction etc.

Hyaluronic acid is one of the most powerful natural moisturizers. In the modern cosmetology hyaluronic acid is on the youth and beauty trend, because due to the great moisturizing ability it makes skin elastic, fresh and smooth and reduces aging factors.

 

How Hyaluronic Acid Work

Hyaluronic acid is a natural substance, which is produced in the human body. Almost 50% of hyaluronic acid is in the skin, the rest is in the tendons, cartilage, nerves and hair. The skin structure is like a water-and-spring mate, there the spring role is played by collagen and elastin and the filling substance is glycosaminoglycans, which retain liquid. The major glycosaminoglycan is a hyaluronic acid. Hyaluronic acid molecules create a kind of net, which attracts large volume of water and hold it. Besides that, hyaluronic acid molecules regulate water balance according to season and climate and synthesize collagen as well.

In the normal metabolic conditions during the day about 1/3 of the whole hyaluronic acid volume disintegrates and creates again, but after the age of 30 disintegrating process become dominate over restoring. As a result, skin obtain a lack of collagen and lose liquid. Modern cosmetic products and procedures allow restore collagen deficiency and remove aging signs.

One of the main causes of skin aging is moisture loss. During this process, not only epidermis experiences the dehydration. Without the required amount of moisture, collagen and elastin fibers lose their elasticity. As a result, the skin becomes dry and flabby, prone to the wrinkles appearance.

Speaking about skin moistening, preservation of its youth and beauty, the hyaluronic acid is the most effective natural element. The effect provided by the hyaluronic acid is unique. The magic of hyaluronic acid lies in its ability to retain great amount of moisture in the skin. Scientists have calculated that one gram of hyaluronic acid can retain up to six liters of water. However, it is not the only wonderful feature of the hyaluronic acid. In addition to the fact that the hyaluronic acid retains moisture in the skin, it can also attract it from the external environment and create a barrier against evaporation.

 

How the hyaluronic acid functions

Hyaluronic acid is a natural structural component of our skin. Until the age of 25, it is presented in our body in the enough quantity and fully implements its functions, maintaining the skin youth, beauty and health. However, after this age, the activity of fibroblast cells, responsible for the hyaluronic acid production, decreases, and the destructive processes prevail over the regenerative ones.

It should be noted that the intensity of these processes is influenced by various factors:

• environment pollution;
• diet;
• excess weight;
• insufficient water intake;
• some diseases of internal organs;
• harmful addictions;
• stress and chronic fatigue.

The list of beneficial effects of hyaluronic acid is not limited to skin moistening; it implements much more functions:

• softens the skin;
• heals microcracks, wounds, scars;
• reduces wrinkles;
• reduces inflammation and provides effective care for problem skin;
• provides nutritional agents to the deep layers;
• creates a protective barrier from external negative influences.

An important positive feature of hyaluronic acid is the fact that it is perfect for all skin types and, as it is a natural element, it has no contraindications.

Hyaluronic acid is a unique polysaccharide and a structural component of a human body, which acts as a main skin moisturizer. Its molecule is called the substance of youth and beauty. There are no any other natural substances with the same features as hyaluronic acid. It plays the leading role in supporting skin tone and preventing wrinkles development, skin slackness and dryness. Taking into account the unique properties of hyaluronic acid, the scientists learned to synthesize it and to use it as an effective treatment against aging changes.

 

What are the beauty procedures with hyaluronic acid

Hyaluronic acid has an ability to bind a large amount of moisture, much larger than its own molecule size. Besides that, hyaluronic acid prevents moisture evaporation from the skin. This substance acts as a kind of filler between collagen and elastin fibers, takes part in their synthesis and keeps skin elastic. Before the age of 25 our body is able to develop the necessary amount of hyaluronic acid, but after this age the processes of substance breakdown prevail its repair. The skin becomes dry, ages, the wrinkles become more apparent.

Our skin responds favorably on synthetic supplementing of hyaluronic acid. Cosmetic industry offers a series of efficient beauty procedures based on hyaluronic acid, which help the skin to stay young and beautiful, and to prevent its aging.

Cosmetic products of topical use with hyaluronic acid, such as creams, masks, gels, lotions have the most affordable price. Their regular application leads to positive effect.

Injectable and laser-based beauty procedures with hyaluronic acid have a more prominent action. This substance is introduced deeply into the skin by injections or modern technologies, smoothens wrinkles and lifts facial contours. Among these beauty procedures are biorevitalization, mesotherapy, redermalization, wrinkle filling, etc.

In 1934 the scientists Karl Meyer and John W. Palmer extracted Hyaluronic Acid from eyes vitreous body and studied its properties. Since then this amazing substance has become famous and cosmetologists and medicals started to find out ways of keeping Hyaluronic Acid in tissues and its replenishment. Hyaluronic Acid has become the most popular skincare ingredient in variety of cosmetic procedures.

The secret of this substance is in the unique ability to bind and hold water. One molecule of Hyaluronic Acid can bind up hundreds of water molecules, which allows it to be a kind of binding agent for connecting the skin cells and regulating intracellular metabolism. Thus, Hyaluronic Acid makes skin firm and elastic and effectively prevents aging. Besides that, Hyaluronic Acid can adapt to the weather conditions in accordance with humidity and regulate the level of water absorption.

 

Hyaluronic Acid use in cosmetics

Like the other substances in human body, Hyaluronic Acid is continuously produced by fibroblasts, a special kind of connective tissue. By the age of 20 their activity become lower and Hyaluronic Acid disintegration start to prevail over the generation and by the age of 30-40 these effects become obvious: skin become dry, rough, wrinkled. The negative factors like unhealthy diet, bad habits, UV-radiation etc. boost this process.

The Hyaluronic Acid cosmetic products are designed to restore the lack of this natural moisturizer and to sloe down aging. Creams, cosmetic masks, gels etc. perform the following list of functions:

• Provide skin with deep moisturizing and prevent the moisture evaporation;
• Soften and smoothen skin, heal chapping and cracking;
• Activates the skin protective functions;
• Fill in and smoothen wrinkles;
• Reduce inflammation and take care of skin;
• Help nourishing agents to get into deep skin layers.

Hyaluronic acid is often called the ‘queen’ of cosmetology. This substance appeared several decades ago and became very popular. It was proven to be a highly efficient product in treating aging skin changes and became a #1 product in skin rejuvenation. There is no other substance like that, that’s why the ‘queen’ keeps the lead.

 

In what forms can hyaluronic acid be used

The main advantage of hyaluronic acid is that it is a natural substance of a human body. It is contained in nervous, epithelial, conjunctive tissues. Its phenomenon is in its ability to bind and keep a large amount of moisture in the skin tissues, thus supporting collagen and elastin fibers. In early years a body can keep a natural balance of hyaluronic acid, that’s why young skin is firm, elastic and toned. After the age of 30 the process of its development slows down. As a result of it, the skin becomes aged – its color becomes dull, facial contours lose their shape, there appear wrinkles.

The experts of beauty medicine and cosmetologists offer a great variety of effective cosmetic products and beauty procedures with hyaluronic acid. This substance can be used in the following forms:

• pills: capsules, powder, ampoules;
• cosmetic products with hyaluronic acid: creams, emulsions, serum, mousse, masks, micellar water;
• beauty procedures using injections: mesotherapy, fillers, biorevitalization.

Hyaluronic acid is one of the most requested cosmetology products nowadays. It has been popular for several decades and it has unique properties in fading skin care. Moreover, hyaluronic acid is a natural structural component of human body and has no contraindications to its synthetic supplementing.

 

How does hyaluronic acid work

85% of human body consists of connective tissue, which can be represented in liquid (intra-articular, cerebrospinal fluids, blood, lymph), gel (cartilaginous tissues, vitreous body, subcutaneous water), solid (bones) forms. Most of the connective tissue exists in epidermis.

The structure of connective tissue consists of collagen and elastin, and also complex molecular compounds of proteins and amino acids. The most important molecule in these compounds is a molecule of hyaluronic acid. The major part of hyaluronic acid in epidermis is contained in horny layer, the rest part supports collagen and elastin fibers and stimulates their development. This feature as well as the ability to bind and keep up to 500 water molecules in subcutaneous layer, helps to keep skin firm and elastic, and to prevent its fading and wrinkles formation.

 

Why is it necessary to supply the lack of hyaluronic acid in the skin

Every day as a result of metabolism there break up and recover up to 70% of total amount of hyaluronic acid in human body. The following factors affect the predominance of its recovery over break down and vice versa:

• aging changes;
• intensity and duration of exposure to ultraviolet radiation;
• balanced and rational nutrition;
• consumption of nicotine and alcohol;
• stressful situations;
• internal organs diseases;
• intake of certain medications, etc.

All these factors affect the hyaluronic acid synthesis. Negative influence and slowdown of metabolism processes decrease the amount of this substance and cause its concentration in the deeper skin layers, thus dehydrating the top level of epidermis. As a result of it, the skin becomes fragile and there appear wrinkles.

Tabloid press and mass media assert hyaluronic acid to be a substance of eternal youth and beauty. It is fair to say that such an estimation has a real background. Hyaluronic acid is as a unique structural component of a human body, which is able to lock in moisture. It exists in epidermis in large quantities and it is in charge of keeping the skin firm, toned and young, preventing fine lines. There almost no precautions against using hyaluronic acid as a component of cosmetic products or beauty procedures, as it is a natural substance of human body. The effectiveness of cosmetics based on hyaluronic acid was proved both by clinical trials and a long-term use. Its positive action depends on the beauty procedure, amount of hyaluronic acid in the cosmetic product and on its molecule size.

 

What alternatives of hyaluronic acid exist

There are no any other natural products with the same wide range of effective actions as hyaluronic acid, except its alternative – a hyaluronic acid derivative with a smaller molecular volume. This is a salt of hyaluronic acid, which is developed with the help of bio-engineering by separation of non-functional components. This substance is called sodium hyaluronate, and being used as an ingredient of cosmetic products, it has much larger spectrum of activity than hyaluronic acid. It is caused by the smaller size of its molecules, which can penetrate into the deep skin layers. In such case, it is better to use high-molecular hyaluronic acid in injection beauty procedures.

Hyaluronic acid is a unique structural component of human body, which is produced by the cells of the conjunctive tissue. A large number of its positive features is caused by its ability to transform to gel at the ratio 1:100 when exposed to water. Owing to this fact and to its hygroscopic property and viscoelasticity, hyaluronic acid is a #1 cosmetology product to fight aging processes. This substance, like a sponge, absorbs moisture from the outside, effectively distributes it among all tissues and makes a barrier against its evaporation. Thus, hyaluronic acid provides deep skin moisturizing, fills in the wrinkles, lifts facial contours. But this is not the whole list of its properties.

 

What are the functions of hyaluronic acid

• it is concerned in collagen and elastin synthesis;
• moves nutrients into the deep skin layers;
• removes half-life materials;
• protects skin cells from negative influence of free radicals;
• reduces wrinkles and prevents their appearance;
• binds water and proteins;
• heals wounds and regenerates cartilaginous tissue;
• solves a problem of dry and exfoliating skin;
• fights acne.

 

What are the consequences of hyaluronic acid deficiency

Unfortunately, the process of hyaluronic acid production starts to decline by the age of 25. This effect is redoubled not only by aging changes, but also by various internal and external factors, such as UV-rays, stresses, unhealthy dieting, smoking. The lack of hyaluronic acid causes negative effects even at an early age – dryness, slackness, premature wrinkles, dull face color, skin vulnerability.

There is a positive fact in solving this problem: human body accepts artificial compensation of hyaluronic acid deficiency, and cosmetology offers a large variety of products and procedures based on hyaluronic acid.

Sodium hyaluronate is a structural component of many human body tissues. It exists in skin, eyes, cartilaginous junctions, nerves. This substance was discovered in 1934 and for a long time its features were unknown. Its active research started from the 50’s. Nowadays it is popular in medicine to recover motor functions, which have been affected by various diseases, in ophthalmology, plastic surgery, etc. In cosmetology sodium hyaluronate is #1 product to keep the skin young and beautiful.

 

Why does the skin need sodium hyaluronate

A need of this component is caused by its ability to moisturize the skin. One molecule of sodium hyaluronate can draw and retain up to 500 water molecules. Moreover, it makes a barrier film against moisture evaporation, fills in and reduces wrinkles and prevents their formation.

 

Under 25 years of age human body successfully copes with needed amount of sodium hyaluronate. After the age of 25-30 this process slows down significantly, the amount of sodium hyaluronate decreases. Receiving less than due, the skin starts fading, there appear wrinkles, the facial contours lose shape. Besides that, the reduction of sodium hyaluronate may be caused by UV radiation exposure, bad habits, stresses, unhealthy dieting. Artificial compensation of this component may significantly remedy this situation and help the skin stay young.
