Injection of hyaluronic acid to fill in wrinkles

Acide hyaluronique en médecine esthétique

It has been used as a perfectly tolerated and absorbable filling implant in the treatment of facial and neck wrinkles for more than 20 years. These are the hyaluronic acid wrinkle filler injections. Once precisely injected, the product will correct and reduce wrinkles.

It can also change volumes, since the appearance of thicker and more concentrated hyaluronic acids:

• hem the lips and plump the mouth

• fill cheeks or cheekbones

• correct the nose or chin

• fill temples that are too hollow

• fill in dark circles …

In principle, no test is necessary because it is not an allergenic substance. Today, good products are very pure and allergies are extremely rare

The various laboratories now offer many products, at varying concentrations and viscosities. They adapt to different indications (reshaping facial volumes, smoothing fine wrinkles, skin revitalization and re-hydration) but also to different skin types.

To fill or smooth a wrinkle, the injection is very superficial (1 to 2 mm). It is done using a very fine needle allowing the immediate erasure of wrinkles and furrows, without over-correction. So the result is immediate. The doctor must know how to vary the depth of implantation of the product to obtain the desired effect (smoothing of a superficial wrinkle, filling of a deep wrinkle or a furrow). The experience of the practitioner makes all the difference in the results obtained.

An additional session may be necessary after 3 to 6 weeks, especially if this is the first time the area is being treated.

To restore lost volumes to a face, the doctor will more readily use a blunt-tipped needle (micro-cannula) to avoid bruising. In fact, the injections are, in this case, deeper and the risk of bruising is greater, especially with conventional needles.

Usually larger amounts of concentrated hyaluronic acid are needed. The cost is therefore higher. Learn more about correcting facial volumes

It is good to repeat the filler injection every six to nine months, sometimes less in the first few sessions. Preferably, one does not wait for the wrinkles or furrows to reappear completely. Products used to reshape volumes (cheekbones, temples, lips, nose correction, deep furrows, etc.) last longer: 12 to 18 months.

The product is almost “natural” because it is identical to that of the human body. The effect of the filler injection is immediate. There are few or no annoying sequels. If the doctor is sensitive, bruises or bruises are rare. Hyaluronic acid is not allergenic so there is no need to test the product before the injection session.

Small redness and swelling in the treated wrinkles can be seen (depending on the skin) and persist for a few hours to a few days after the injection. Hyaluronic acid is absorbed more or less quickly and requires regular sessions but, in general, the effect stays better and better with the sessions.

Side effects are very rare with the good hyaluronic acids available to doctors today. We have seen exceptionally: itching for a few weeks, granulomas (induration, swelling and local redness). These effects are reversible and it is possible to quickly dissolve the injected hyaluronic acid by injecting a specific product: hyaluronidase.
