What is hyaluronic acid ?

It is a protein that occurs naturally in all living organisms. Hyaluronic acid is a very powerful and effective moisturiser.

Anti-ageing of the skin: Injection of hyaluronic acid can effectively delay the ageing process until it has completely stopped. Hyaluronic acid is commonly used as a filler in aesthetic medicine.

Hyaluronic acid is present in large quantities in the skin tissue of our body, giving the epidermis firmness, elasticity, softness and suppleness.

Disadvantages : With time and age, the hyaluronic acid content of the body’s skin will gradually decrease.

For hyaluronic acid, autoimmune diseases and pregnancy are contraindications to be respected! You can talk to your doctor.

 

Doctor, don't overdo it, let the results come naturally! Doctor, don't let my husband see anything!

What is hyaluronic acid made of ?

It is a natural component molecule of more than 80% of the dermis reconstituted in the laboratory, synthetic and purified. It is injected through a micro cannula. It is a transparent and absorbable gel.

Note that more injections won't bring back your childhood cheeks - so don't go around asking for more and more so that you don't end up with the bloated face you sometimes see on the street or on our screens.

  • The treatments are carried out at the aesthetic centre in Paris 16e and last from 20 to 45 minutes depending on the area to be treated.
  • The treatment is administered by injection. The needle penetrates a few millimetres into the dermis to inject the hyaluronic acid.
  • In some cases, a blunt-ended injection cannula is used, which is less invasive and less painful, thus limiting the risk of bruising.
  • Since it is a biodegradable product, it is naturally consumed by the body.
  • A facial modelling (facial massage) at the end of the procedure followed by a make-up.

What are the injection techniques for a hyaluronic acid treatment ?

In the fight against wrinkles and skin ageing, this technology allows the face to be rejuvenated without plastic surgery. This is the most popular method for facial rejuvenation.

Which parts of the face can be treated ?

Improve facial contours by restoring volume :

  • Wrinkles : nasolabial folds (from the nose to the corners of the mouth), bitter folds (at the corners of the mouth, on both sides of the chin) and labial folds (fold of the lips).Hyaluronic acid injection 11
    • Wrinkles and fine lines : forehead, « frown lines » (between the eyebrows), « crow’s feet » (corner of the eyes), cheeks, chin and « sun creases » around the mouth.

  • Lips : redraw the hem (contour), if they are too thin, thicken them or make them fuller.

Hyaluronic acid injection 13

  • Depression (sagging) or low volume: cheekbones, dark circles, chin, jawline (Jawline), cheeks, nose, temporal fossa, scarring (acne, chicken pox, trauma, etc)

What if you are not satisfied with the treatment ?

If the results are not suitable for the patient, we have another injectable product that melts the hyaluronic acid within 4 hours. Massage is also recommended to spread it. As a result, the previous injection has been dispensed with.

Hyaluronidase is not officially approved in France, due to severe allergies, the product should be used with caution.
This filling product is suitable for example for nasolabial folds, our “smile parentheses”: when they are very visible, two injections are necessary: the first to tighten the cheekbones and smooth the bulges that form along the fold, then the second to fill the fold.

What are the benefits of hyaluronic acid ?

  • Hyaluronic acid hydrates the skin
    Absorbable product
  • Results : At the end of the treatment, hyaluronic acid has an immediate effect on wrinkles.
  • The final results are only visible ten days after the treatment.

How long does the effect last ?

Only in each case, the effects of the hyaluronic acid injections last between 3 and 8 months.
Over time, it is recommended to repeat the entire process.
Swelling and redness may occur after the treatment, but will disappear within 24 to 48 hours. Modifications (touch-ups) can be made a few days after the session to optimise the final result.

Contraindications and warnings :

There may be temporary reactions in the treated area: swelling, oedema, redness, bruising, some sensitivity, itching, etc.

It is best to avoid exposure to the sun and high temperatures. Avoid UV sessions after injection.
Disadvantages: In very cold weather, you may feel the product freeze and harden on your face.

Side-effects and complications

Complications of filling and volume measurements are extremely rare :

Some cases have been described as redness, abscesses or skin necrosis persisting for several weeks, confined to the injection site.

However, several reactions may be observed :

  • Local reactions after injection : Sometimes swelling, redness, pallor, irregularity, tenderness, itching and bruising may occur. However, these reactions are only temporary.
  • Outbreak of cold sores : in sensitive individuals.
  • Acute or chronic inflammatory reaction : This reaction may occur after a second injection in an area where other products (especially non-absorbable products) have been injected.
  • Granuloma : Although rare, this is the most « classic » complication. They are small, hard nodules, more or less sensitive, palpable, sometimes visible and unsightly.
    They correspond to local inflammatory responses and may develop in flare-ups. They may appear a few days to a few weeks after the injection. Indeed, these granulomas are very rare for resorbable products, and even exceptional for hyaluronic acid. Moreover, they degenerate spontaneously within a few weeks.

May be allergic to hyaluronic acid injections :

The hyaluronic acid molecules used are of chemical origin. There are several families of hyaluronic acid (about 50), but only 6 are authorised in the United States. This is because the requirements of the American health authorities are very strict, stricter than here, with rigorous registration and extensive clinical studies before any marketing authorisation. For example, of the 26 laboratories in which we sell their products in France, only a few are authorised for the American market.

Therefore, you should ask your doctor about the source and composition of the products he or she is considering using. Traceability allows lists of preservatives contained in products to be established. The label carries the batch number, indicating the traceability of the product

Although the substance itself rarely causes allergies, the preservatives in the product are the cause of the allergic risk. Before a new injection, a treatment booklet (follow-up booklet) is essential, in which the name of the product, the name of the manufacturer, the batch number and the injection instructions are recorded.

In addition to these known risks, there are the unpredictable aspects and duration, and finally the unusual, even unknown, risks inherent in any medical practice. In general, the risks should not be overestimated, but it should be realised that even with apparently simple medical treatments, there are always risks.

The French National Agency for the Safety of Medicines and Health Products (ANSM) has banned hyaluronic acid injections in the breasts because of the risks they may pose.

Because of the risk of developing granulomas 10 to 15 years after the injection, non-absorbable products or silicones (banned in France) should be avoided.
