What is hyaluronic acid and how does it work?

What is hyaluronic acid

Hyaluronic acid is perhaps one of the most famous beauty ingredients. Even people far from the beauty industry have heard about it. However, knowledge about hyaluronic acid is often limited to the fact that it reduces wrinkles. In reality, not everything is so simple.

What is hyaluronic acid?

Hyaluronic acid is the most versatile "beauty molecule". It was discovered in 1934 by Carl Meyer and his assistant John Palmer.

Hyaluronic acid is found in bones, connective tissue, cartilage, hair follicles, and skin. At the same time, almost half of hyaluronic acid is present in the skin, where, acting like a magnet, it binds to water, slowing down the speed of its evaporation and helping cells retain moisture. Just 1 g of hyaluronic acid has the impressive capacity to hold up to 6 liters of water. Add to this the ability to regulate humidity levels within cells and you have a phenomenal cellular component. It allows the skin to maintain a high level of moisture, remain elastic and healthy.

Thus, hyaluronic acid has three main effects:

  • anti-aging;
  • moisturizing;
  • wound healing.

Hyaluronic acid can be destroyed by free radicals under the influence of ultraviolet radiation, tobacco smoke and a polluted environment.

How to understand that your skin needs hyaluronic acid

After 25 years, skin cells produce less hyaluronic acid. This occurs due to a slowdown in the cells' ability to divide and retain moisture. Dehydrated skin has an uneven structure, is dotted with fine wrinkles and has a dull appearance.

To keep the skin soft, elastic and luminous, from the age of 25 you can include creams and preparations with hyaluronic acid in your daily care, and from the age of 30 you can also include a hyaluronic serum.

hyaluronic acid supplements

Hyaluronic acid supplements

In case of a lack of hyaluronic acid, it is recommended to take appropriate supplements. Studies have shown that taking between 120 and 240 mg of hyaluronic acid daily for at least a month significantly improves skin hydration and reduces dryness. Food supplements with hyaluronic acid can be taken from the age of 20.

Why don't products with hyaluronic acid work?

If the skin is sufficiently hydrated, products containing hyaluronic acid can clump when applied, so it is not necessary to use this component at this time.

If after using a cream or serum with hyaluronic acid there is a film sensation on the skin, then the skin does not need hyaluronic acid.

What skin type are products with hyaluronic acid suitable for?

There are three main types of skin:

  • normal;
  • dry;
  • fatty.

Skin of any type can experience dehydration and sensitivity conditions. That is, both oily and normal skin can become dehydrated. It is important not to confuse dehydration with dry skin type. The cause of dry skin is a lack of lipids, not water.

What names can hyaluronic acid have on the packaging?

Hyaluronic acid has the following names:

  • hydrolyzed hyaluronic acid;
  • acetylated hyaluronate;
  • sodium hyaluronate;
  • Sodium salt of hyaluronic acid.

What skin care products contain hyaluronic acid?

Serums

They have a light texture, minimal composition and are distinguished by the highest concentration of hyaluronic acid. In addition, the texture of the serum allows the hyaluronic acid to penetrate the skin faster. It is best to use a combination of large and small molecules to provide immediate hydration to the top layer of the skin and longer-lasting effects to the lower epidermis.

How to properly use hyaluronic acid serum

It is very important to apply the hyaluronic acid serum correctly. The fact is that if you apply a serum with hyaluronic acid to dry skin in a humid room without subsequently applying cream, the serum will draw moisture from the air and create a feeling of tightness without drying out the face. If the skin is hydrated and the room is dry, the hyaluronic acid present on the surface of the face will draw water from the skin and evaporate it into the air, creating a feeling of dryness.

Therefore, it is important to apply a hyaluronic acid serum to slightly damp skin; You can spray your face with thermal water or not dry it completely with a towel, and after the serum, immediately apply a moisturizer to "seal" the hyaluronic acid into the skin. fur. In this way the moisturizing effect will be maximum. This scheme is suitable for any skin type.

skin cleansers

Cleaning products

Syndents with sodium hyaluronate will help remove makeup, dirt and excess sebum. The product is applied to damp skin and then washed off.

Lotion with sodium hyaluronate.

It can be used for both face and body.

Gel with sodium hyaluronate

The gel should be applied to the skin until completely absorbed.

Facial cream

Hyaluronic acid is a "team player" that works best when combined with a cream.

What are the side effects of using hyaluronic acid?

Hyaluronic acid is perhaps the most harmless ingredient for the skin in terms of side effects. Since hyaluronic acid is a normal part of the skin, an allergic reaction is very rare.

The use of this acid, unlike glycolic, salicylic and others, does not aim to renew the epidermis, but rather to hydrate and maintain the hydrolipid mantle of the skin. Therefore, it does not "expose" the skin and does not cause redness. Its use applied topically does not stimulate the skin's exfoliation processes.

If side effects occur after using a product containing hyaluronic acid, you should pay attention to the composition of the product; allergies to other ingredients may occur. This reaction can result from using too high a concentration of hyaluronic acid. Therefore, to avoid irritation or dryness, it is recommended to avoid concentrations of hyaluronic acid greater than 2%.

It's also wise to do a preliminary "patch test": apply a small amount of any new product to the back of your wrist and evaluate side effects for 24 hours. If you experience any side effects after using hyaluronic acid, you should consult a dermatologist.

During pregnancy or breastfeeding, it is safe to use external preparations containing hyaluronic acid.

What should be hyaluronic acid for rejuvenation

What should be hyaluronic acid?

The benefits of hyaluronic acid depend directly on its molecular weight and concentration. The diameter of the hyaluronic acid is also important as it determines the ingredient's ability to penetrate the skin.

Molecular weight is measured in so-called atomic mass units: daltons or kDa. Hyaluronic acid weighing between 50 and 1000 kDa is the most beneficial for the skin; a weight of approximately 130 kDa is considered optimal. Exceeding this indicator has no qualitative importance.

Why does the 130 kDa weight have the maximum effect?

In one study, researchers evaluated the effects of hyaluronic acid on skin with different molecular weights, including 50, 130, 300, 800, and 2000 kDa. A month after starting to use topical preparations with different weights of acid, experts found that using 130 kDa was the most effective: skin elasticity increased by 20%. Both the 50 kDa and 130 kDa groups experienced significant reductions in wrinkle depth and skin roughness after 60 days. All other molecular weights also increased skin elasticity and hydration, but to a lesser extent.

What components does hyaluronic acid combine well with?

If you are looking for a pair of ingredients for optimal skin care, choose hyaluronic acid and vitamin C. They complement each other and promote maximum hydration, protection and restoration of the skin.

There's another reason why these ingredients work well together: too much vitamin C can cause irritation, dry skin and even acne, and hyaluronic acid not only soothes and repairs the skin, helping to create a moisture barrier, but it acts as a an excellent messenger, delivering vitamin C to cells.

Other medical benefits of hyaluronic acid

In addition to its excellent cosmetic effect in skin care, sodium hyaluronate has other medical indications for use.

Osteoarthritis of the knee joint.

Hyaluronic acid is found in joint fluid and cartilage. However, with osteoarthritis, sodium hyaluronate levels in the joints decrease. A sodium hyaluronate injection may help with osteoarthritis in the knee. The medication is injected directly into the knee and helps reduce pain in this area.

eye surgery

Sodium hyaluronate drops are useful in procedures such as:

  • corneal transplant surgery;
  • glaucoma correction;
  • secondary implantation of an intraocular lens;
  • cataract surgery.

Thanks to its anti-inflammatory and moisturizing effects, sodium hyaluronate reduces dry eyes that can occur after surgery.

Nasal spray with sodium hyaluronate.

This product is effective in hydrating and regenerating the mucosa of the sinuses.

Hyaluronic acid injections

Injectable anti-wrinkle fillers can provide a plumped appearance to the skin in a gentler manner than a traditional facelift. Most fillers or fillers fill gaps, lines and wrinkles in less than 30 minutes and provide results that can last 4 months to a year.

What effect do the injections have?

The scope of application of hyaluronic acid gel is wide:

  • wrinkle smoothing
  • lip augmentation
  • facial contour modeling
  • intensive skin hydration

The most popular category of wrinkle fillers is hyaluronic acid. Each type of medication works differently and produces different results.

injections with hyaluronic acid

Side effects

Side effects from these injections are rare, but may include:

  • redness;
  • edema;
  • bruising at the injection site.

Filler may also appear under the skin as small bumps, but they will disappear within a day.

If you take blood thinners, the injection site will bleed more and may cause slight bruising.

What you should know before hyaluronic acid injection

  • You should not be guided solely by the price of the procedure.
  • If you are offered wrinkle correction at a significantly lower price, the craftsmanship or quality of the product may leave a lot to be desired.
  • The procedure should be performed exclusively in a medical center.
  • Procedures should be performed exclusively in a medical setting, regardless of who performs them.
  • Always ask for the name of the medication.
  • Before the injection, the specialist must announce the name of the medicine and show how he opens the new package. If the specialist does not provide this information, it is better to refuse the procedure.

Use sunscreen daily. This will help prolong the effect of the filler and protect against post-inflammatory pigment changes that may occur at the injection site.

Special precautions when performing hyaluronic acid injections.

The pregnancy

There is no data confirming the safety of hyaluronic acid injections during pregnancy.

Breast-feeding

There is also no data yet on the safety of hyaluronic acid injections during breastfeeding and their effect on the child.

Associated visible skin diseases.

The application of hyaluronic acid can worsen the skin condition in people with scleroderma. With this pathology, the topical use of products with hyaluronic acid is inappropriate.

How is hyaluronic acid injection performed?

Hyaluronic acid is injected under the skin with a fine needle in small volumes. Depending on the sensitivity to pain and the injection site, it is possible to previously apply an anesthetic cream or use local anesthesia by injecting an anesthetic into the skin. When using a topical anesthetic, the anesthetic effect occurs within 2-3 minutes.

In which areas of the face are hyaluronic acid injections used?

  • glabellar lines in combination with botulinum toxin;
  • nasolabial lines and "marionette lines";
  • Fine wrinkles around the mouth and lips.

It must be remembered that superficial or very deep wrinkles are difficult to treat. In these cases, the doctor may recommend a combination of hyaluronic acid gel with another drug and subsequent selection of skin care.

How long does the hyaluronic acid injection procedure take?

The procedure lasts between 15 and 60 minutes. But since the lip area is much smaller compared to other injection areas, the duration of work on it is also shorter.

How long does the effect of hyaluronic acid treatment last?

The duration of action varies from patient to patient and depends on many factors, including lifestyle, skin type, age, and injection technique. For example, after lip augmentation, at least six months should pass before the next injection of the medication.

What skin care treatments can hyaluronic acid be combined with?

Hyaluronic acid combines with most other ingredients, including exfoliants, retinols, vitamins, and other acids. The only exception is acids with low pH levels, such as glycolic acid, because they can inhibit the action of hyaluronic acid and significantly reduce its effectiveness.

What to do after injecting fillers at home.

  • Avoid massaging or rubbing treated areas for the first 48 hours after treatment.
  • During the first eight hours after the procedure, you should not unnecessarily touch the treated areas of your face. Afterwards, you can wash your face with soap and apply light makeup.
  • Until the initial redness and swelling of the skin subsides, extreme heating of the skin (tanning beds and sunbaths) and hypothermia should be avoided.

Is it possible to remove hyaluronic acid after treatment?

No. If you are not satisfied with the result, you can carry out the treatment progressively until you achieve the desired effect.

What is biorevitalization?

Biorevitalization is a form of mesotherapy that uses higher concentrations of hyaluronic acid. It should not be confused with filler, which acts as a filling material for wrinkles and does not provide nutrients to the skin.

Biorevitalization can be used on the neck, neckline, arms, hands and area around the knees.

The main goal of the therapy is to fill the skin with hyaluronic acid, which stimulates the natural production of collagen, hyaluronic acid and active metabolism under the skin, contributing to its rejuvenation.

before and after using hyaluronic acid

To do this, purified hyaluronic acid of non-animal origin is injected into the skin. This means that it is synthesized from bacteriological strains of streptococci, is completely organic for the human body and does not cause adverse reactions. This method of skin rejuvenation is considered simpler than other cosmetic procedures, but no less effective.

Biorevitalization is recommended after 25-30 years, when the amount of native hyaluronic acid begins to decrease significantly and the skin intensively loses moisture. This causes loss of tone and elasticity, increased dryness and a tendency to inflammation. The result is visible after the first procedure, but to obtain the ideal effect it is necessary to undergo treatment.

What is mesotherapy?

Mesotherapy is the rejuvenation of tired tissue. The main goal of the technique is to enrich the skin with beneficial substances and nutrients. Thanks to injections, this process is deeper and more intense than with the use of creams and masks. Depending on the goals of the correction, the doctor selects a ready-made solution or prepares it individually, taking into account the characteristics of the patient's body.

The components of mesotherapy can be:

  • hyaluronic acid;
  • vitamin and mineral complexes;
  • amino acids, antioxidants;
  • peptides;
  • phytoextracts.

The procedure is performed with very fine needles. Mesotherapy has a long-lasting effect after the first injection session and allows a wide range of problems to be solved. It is aimed at improving the general condition of the skin, normalizing microcirculation in cells and intercellular space, increasing tissue elasticity and eliminating various aesthetic defects. The youth and freshness of the skin lasts up to ten months and can be maintained with repeated injections.

What to choose: mesotherapy or biorevitalization.

There is no clear answer. Injections for biorevitalization contain only hyaluronic acid, which is necessary, first of all, to moisturize and restore damaged tissues.

Mesotherapy cocktails are a whole complex of biologically active components that have a complex effect on tissues and can solve several aesthetic problems at once.

Mesotherapy will also help when there are specific problems, such as:

  • dark circles and bags under the eyes;
  • cellulitis;
  • Hair loss;
  • cicatrization.

Mesotherapy includes both superficial injection of drugs to a depth of 2 mm and deep punctures.

Thus, for patients 30 years of age and older, mesotherapy is optimal, which is especially relevant when it comes to solving cosmetic problems associated with acne and scars, and biorevitalization will be the best option for patients over 25 years of age.
