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 the rate of its evaporation and helping cells retain moisture. Just 1g of hyaluronic acid has the impressive capacity to retain up to 6L of water. Add to this the ability to regulate moisture levels within cells and you have a phenomenal cellular component. Allows the skin to maintain a high level of hydration, 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 appears dull.
To make your skin soft, elastic and shiny, from the age of 25, you can include creams and preparations with hyaluronic acid in your daily care, and from the age of 30, also hyaluronic serum.
Hyaluronic Acid Supplements
If there is a lack of hyaluronic acid, it is recommended to take appropriate supplements. Studies have shown that taking 120-240 mg of hyaluronic acid per day for at least a month significantly improves skin hydration and reduces dryness. Dietary supplements with hyaluronic acid can be taken from the age of 20.
Why don't hyaluronic acid products work?
If the skin is sufficiently hydrated, products containing hyaluronic acid can accumulate upon application, which means there is no need to use this component at this time.
If after using a cream or serum with hyaluronic acid there is a feeling of film 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 skin types:
- normal;
- dry;
- little fat.
Skin of any type can experience dehydration and sensitivity. In other words, both oily and normal skin can become dehydrated. It is important not to confuse dehydration with dry skin. The cause of dry skin is a lack of lipids, not water.
What names can hyaluronic acid have on packaging?
Hyaluronic acid has the following names:
- hydrolyzed hyaluronic acid;
- acetylated hyaluronate;
- sodium hyaluronate;
- hyaluronic acid sodium salt.
Which skincare products contain hyaluronic acid
Serums
They have a light texture, minimal composition and are distinguished by a higher concentration of hyaluronic acid. Furthermore, the texture of the serum allows hyaluronic acid to penetrate the skin more quickly. 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 on the lower epidermis.
How to properly use hyaluronic acid serum
It is very important to apply hyaluronic acid serum correctly. The fact is that if you apply a serum with hyaluronic acid to dry skin in a humid environment without subsequently applying a 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 environment 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 dry sensation.
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 in the skin. skin. skin. This way the moisturizing effect will be maximum. This scheme is suitable for any skin type.
Cleaning products
Syndents with sodium hyaluronate help remove makeup, dirt and excess sebum. The product is applied to damp skin and then washed off.
Lotion with sodium hyaluronate
Can be used on both the face and body.
Gel with sodium hyaluronate
The gel must 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 to it is very rare.
The use of this acid, unlike glycolic, salicylic and others, is not aimed at renewing the epidermis, but rather at hydrating and maintaining the skin's hydrolipidic mantle. Therefore, it does not "expose" the skin and does not cause redness. Its use when 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 hyaluronic acid concentrations above 2%.
It is also advisable to do a preliminary "patch test" – apply a small amount of any new product to the back of your wrist and assess the side effects for 24 hours. If you experience any side effects after using hyaluronic acid, consult a dermatologist.
During pregnancy or breastfeeding, the use of external preparations containing hyaluronic acid is safe.
What should hyaluronic acid be?
The benefits of hyaluronic acid depend directly on its molecular weight and concentration. The diameter of the hyaluronic acid is also important because 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 most beneficial for the skin; a weight of around 130 kDa is considered ideal. Exceeding this indicator has no qualitative significance.
Why does the 130 kDa weight have maximum effect?
In one study, researchers evaluated the effects of hyaluronic acid on skin with different molecular weights, including 50, 130, 300, 800 and 2, 000 kDa. A month after starting to use topical preparations with different acid weights, experts found that using 130 kDa was the most effective - skin elasticity increased by 20%. Both the 50 kDa group and the 130 kDa group 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, opt for 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 acts as 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, in osteoarthritis, sodium hyaluronate levels in the joints become low. An injection of sodium hyaluronate can help treat osteoarthritis in the knee. The medicine is injected directly into the knee and helps reduce pain in that region.
Eye surgery
Sodium hyaluronate drops are useful in procedures such as:
- corneal transplant surgery;
- glaucoma correction;
- secondary intraocular lens implantation;
- Cataract surgery.
Thanks to its anti-inflammatory and moisturizing effects, sodium hyaluronate reduces dry eyes that may occur after surgery.
Nasal spray with sodium hyaluronate
This product is effective for hydrating and regenerating the sinus mucosa.
Hyaluronic acid injections
Injectable wrinkle fillers can provide a lifted appearance to the skin in a gentler way than a traditional facelift. Most fillers or fillers fill in cavities, lines and wrinkles in less than 30 minutes and provide results that can last from 4 months to a year.
What is the effect of the injections?
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 filler is hyaluronic acid. Each type of medication works differently and produces different results.
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 it will disappear within a day.
If you take blood thinners, the injection site will bleed for longer 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, it is possible that the finish or quality of the product leaves a lot to be desired.
- The procedure must be carried out exclusively in a medical center.
- Procedures must be performed exclusively in a medical environment, regardless of who performs them.
- Always ask for the name of the medicine.
- Before the injection, the specialist must announce the name of the medicine and show how to open the new packaging. If the specialist does not provide this information, it is best to refuse the procedure.
Use sunscreen daily. This will help prolong the effect of the filler and protect against post-inflammatory pigmentary changes that may occur at the injection site.
Special precautions when performing hyaluronic acid injections
Pregnancy
There is no data confirming the safety of hyaluronic acid injections during pregnancy.
Breast-feeding
There is also still no data on the safety of hyaluronic acid injections during breastfeeding and their effects on the child.
Associated visible skin diseases
Applying hyaluronic acid may worsen the skin condition in people with scleroderma. In 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 pain sensitivity and the injection site, it is possible to pre-apply a numbing cream or use local anesthesia in the form of an anesthetic injection into the skin. When using a topical anesthetic, the anesthetic effect occurs within 2 to 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 is important to remember 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 medication and subsequent skin care selection.
How long does the hyaluronic acid injection procedure take?
The procedure takes 15 to 60 minutes. But as the lip area is much smaller compared to other injection areas, the working duration 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 must pass before the next injection of the medicine.
What skin treatments can hyaluronic acid be combined with?
Hyaluronic acid combines with most other ingredients, including peels, retinols, vitamins, and other acids. The only exception are 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 the treated areas during the first 48 hours after treatment.
- During the first eight hours after the procedure, you should not touch the treated areas of your face unnecessarily. Later, 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 sunbathing) 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 gradually until you obtain 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 wrinkle-filling material and does not provide nutrients to the skin.
Biorevitalization can be used on the neck, décolleté, arms, hands and areas around the knees.
The main objective 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, which contributes to its rejuvenation.
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 easier than other cosmetic procedures, but no less effective.
Biorevitalization is recommended after 25–30 years, when the amount of native hyaluronic acid begins to significantly decrease and the skin intensively loses moisture. This leads to loss of tone and elasticity, increased dryness and a tendency to inflammation. The result is visible after the first procedure, but for optimal effect it is necessary to undergo a treatment.
What is mesotherapy
Mesotherapy is the rejuvenation of tired tissues. The main objective of the technique is to enrich the skin with beneficial substances and nutrients. Thanks to injections, this process is deeper and more intense than using creams and masks. Depending on the goals of the correction, the doctor selects a ready-made solution or composes 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 lasting effect after the first injection session and allows you to solve a number of problems. Its purpose is to improve the general condition of the skin, normalize microcirculation in cells and the intercellular space, increase tissue elasticity and eliminate 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 where there are specific problems, such as:
- dark circles and bags under the eyes;
- cellulitis;
- hair loss;
- scars.
Mesotherapy includes superficial injection of medicines to a depth of 2 mm and deep punctures.
So, for patients aged 30 and over, mesotherapy is ideal, which is especially relevant when solving cosmetic problems associated with acne and scars, and biorevitalization will be the best option for patients over 25 years old.
