Contrary to what many think, hyaluronic acid is a substance present in our body, as a fundamental component of connective tissues. This substance, in fact, gives the skin elasticity and resistance and, lacking it, would cause a significant weakening of the skin, favoring the formation of wrinkles. The highest concentration of hyaluronic acid is contained in the vitreous humor, which is the gelatinous area inside the eye, as well as in the joints.
Chemically speaking, hyaluronic acidIt is considered a glycosaminoglycan: the molecule is made up of long sequences of two simple sugars. These sugars, in fact, are glucuronic acid and N-acetylglucosamine; two negatively charged substances which when combined give rise to a linear and extremely polar molecule. Hyaluronic acid forms intramolecular hydrogen bonds, which develop macromolecules capable of conferring a reticular structure.

Hyaluronic acid: how many types are there
Hyaluronic acid is not one by definition: in fact, if we consider the molecular weight, we can recognize three different types . High molecular weight hyaluronic acid, which has high moisturizing capacities and remains more on the surface, followed by the medium weight and low molecular weight one. The second has medium level moisturizing capacities and remains on the skin; while the third stimulates the production of collagen reaching the deeper layers of the skin.
Furthermore, when considering the medical use of this substance, linear and cross-linked hyaluronic acid must be identified. The first, in particular, is used for biorevitalization, that is a treatment that consists in the stimulation of the dermal tissue that needs to be reactivated.
The second, on the other hand, is usually used in aesthetic medicine as a sort of filler or so-called “filler”, after having undergone a cross-linking process and being made resistant to hyaluronidase. Cross-linking, in simple terms, consists of a chemical-physical change, for which the acid molecule is conjugated with one that is proposed as a cross-linking agent: this gives greater viscosity. What is hyaluronic acid really good for
Hyaluronic acid, as we said earlier, is very important as it confers elasticity and hydration to the skin. In this way, the skin maintains a certain tone thanks to its ability to retain water: constant hydration of the skin is maintained.
But hyaluronic acid not only helps to keep the skin young , but is an excellent ally against the possible penetration of viruses and bacteria, acting as a powerful barrier. Furthermore, its particular composition does not make it an attractive tool only in the field of aesthetic medicine, but is also a perfect substance for healing, thanks to its known anti-inflammatory properties. Hyaluronic acid for the face
It is now well documented that hyaluronic acid is widely used to combat the signs of aging on the face . In fact, hyaluronic acid injections are ideal for correcting certain points on the face that lose their elasticity and shine over time: lips, cheekbones, nasolabial folds, periocular wrinkles, neck and face remodeling. In all these cases, hyaluronic acid is injected through a syringe under the skin: the pain is very minimal, we would dare to speak of a slight discomfort.
The aesthetic result is not completely permanent, as the product can be reabsorbed: the duration varies from 2 months to 2 years, approximately. This means that, once the substance has been injected, it is readily metabolized and absorbed by the body at different times based on the area treated. For this reason it is advisable to repeat the treatment every 6-12 months , in agreement with the doctor. Hyaluronic acid for the lips
You have surely heard of the lip filler: this is nothing more than the hyaluronic acid injected to correct the imperfections of the mouth. In this particular case, hyaluronic acid is used to give greater volume to the lips, reshape the contour, correct the lowering of the corners of the mouth due to normal skin aging.
The lip filler acts in a very simple and direct way: it smoothes wrinkles and gives volume and harmony, exerting a filling action. Hyaluronic acid is injected into certain points, according to very specific rules in order to fill the less toned areas and give them considerable elasticity. The type of fillerused is decided in advance by the doctor based on various factors, including the result and the type of volume to be obtained, as well as the duration, even if we have already stated that the effect is not permanent over time.
In this regard, there are different types of fillers depending on the needs: resorbable, permanent and semi-permanent fillers. The absorbable or biological ones are mostly made up of natural substances which, once injected, are gradually metabolized by the body. Therefore, the effects and duration are temporary: from a couple of weeks up to 6 months. Positive note of this type and the ease with which they are tolerated.
The permanents,instead, they are composed of synthetic elements and therefore very persistent over time. However, they have a series of disadvantages that it is very useful to mention: significant, in fact, is the risk of incurring unpleasant allergic reactions and consequent side effects. Finally, the semi-permanent ones are made up of both natural and synthetic components and are reabsorbed quite easily even if in a bit longer than the biological ones. In fact, we are talking about 1-2 years generally.
The real and palpable benefit that is obtained from this type of treatment is precisely more voluminous and harmonious lips, thanks to the filling effect. Furthermore, the results are visible right away. Hyaluronic acid for the knee and joints
Did you know that hyaluronic acid is perfect for healing joints
. In particular, the knee, may require injections of this substance and treat arthritic syndromes. Arthrosis, in fact, is a very widespread degenerative disease of the joints. It accompanies the subjects during the aging process: we can imagine that hyaluronic acid acts as an oil and in its absence it creates friction. In this regard, hyaluronic acid infiltrations
are widespreadin the knee: they improve its functioning and decrease any pain. Also in this case, of course, the action of the product is not lasting over time and there is a need for a repetition of the treatment every 6-12 months. This could be a really good solution, perhaps too underestimated still by those who do not know the benefits of this substance. Hyaluronic acid for dark circles
Maybe you are not current, but it is possible to correct dark circles with a few injections of hyaluronic acid: the so-called dark circles filler. Dark circles, in fact, are a very widespread imperfection that makes the appearance very tired and low in tone. In this area, most of the signs of aging and fatigue are highlighted. The periocular area, in fact, is very delicate and subject to this type of problem, but today it is possible to say goodbye to this very annoying form of imperfection.
Hyaluronic acid has an important action by which it fills the lower orbital part . It is clear that the quantity of product injected to revitalize the area varies according to the need to intervene. The treatment lasts about 20 minutes and the result is really immediate: it is not permanent but has a good duration of 1 year. To try, no
It may be ideal for you if you want to get rid of the signs of fatigue.
Furthermore, it is good to specify how this is a non- invasive treatment , without the need for any anesthesia. And then without complications. It is only probable that after the injection there will be a slight form of redness or swelling, but it is completely normal if we consider that you choose to treat a very delicate area. Finally, this type of filler is a latest generation product that allows you to treat very particular areas of the face, avoiding having to intervene with a scalpel. The benefits and contraindications of hyaluronic
acid Hyaluronic acid is very advantageous and useful for the treatment, as well as prevention of various pathologies. And ideal forfight aging and the typical skin signs associated with it. In fact, this substance is not only absorbed by syringe, and therefore injections, but is also present in the form of a cream. It is also easily available.
Basically, hyaluronic acid has a series of benefits that should be emphasized. First, it contributes to the lubrication of the joints and to maintain their mobility. Then, it aims to keep the skin young and hydrated and, in the case of the lips, gives them volume and well-being. Finally, it gives freshness and luminosity to those areas of the face that may appear dull and empty, marked by the passage of time.
It does not appear that hyaluronic acid has particular contraindications.In fact, it does not interfere with the intake of drugs and, only in exceptional cases, could trigger allergic reactions. During the period of pregnancy, however, it is preferable not to take hyaluronic acid, in any form. The same goes for the moment of breastfeeding.
We strongly recommend that you consult your doctor before taking the substance, precisely to avoid incurring side effects, such as diarrhea, stomach pain and irritation of various kinds. If you’re not sure if you can take hyaluronic acid, try asking your doctor .
