Medical genioplasty with hyaluronic acid is today a recognized non-surgical alternative to chin surgery. Quick, effective, and reversible, this technique allows modification of the chin’s shape and projection without general anesthesia or social downtime. But one question often arises among patients : what is the actual duration of the results obtained? How long does the injected gel remain in place? Is it necessary to plan regular touch-ups?
On this page, we analyze in detail the longevity of hyaluronic acid injected into the chin, taking into account the most recent medical data and observed clinical factors.
The duration of the results of a medical genioplasty depends on several factors specific to the patient and the product used. On average, the effects last between 12 and 18 months, and can sometimes extend up to 24 months when conditions are optimal.
This longevity is greater than that observed in other areas of the face. The chin is, in fact, an anatomically less mobile region (it is less mobile than the lips or cheeks), less affected by daily muscle contractions, and less vascularized, which naturally slows the resorption of hyaluronic acid.
Another key factor lies in the choice of injected products. For the chin, the doctor uses highly cross-linked, high-viscosity hyaluronic acids, specially designed to provide structural projection and maintain a deep and lasting result. This combination of anatomical stability and product quality explains why chin injections have remarkable longevity, and maintenance is generally limited to an annual touch-up session.
Several factors can influence the duration of the results obtained.
Most doctors recommend a maintenance session between 9 and 12 months after the first hyaluronic acid injection in the chin. At that point, the results begin to fade slightly. A targeted touch-up is then enough to maintain projection, profile balance, and overall harmony of the lower face, without having to wait for the complete disappearance of the injected product.
A regular maintenance routine offers several advantages: it helps preserve a natural result, avoid overly marked aesthetic variations, and adapt the treatment to the evolution of facial morphology over time. Thanks to this approach, the chin maintains a stable and harmonious definition.
Certain habits and maintenance care can significantly prolong the results of a medical genioplasty with hyaluronic acid injection in the chin :
The hyaluronic acid injected into the chin is not permanent. It is a completely resorbable substance, naturally eliminated by the body over time. Unlike a silicone chin implant or certain semi-permanent fillers, hyaluronic acid is gradually broken down by physiological enzymes, mainly by endogenous hyaluronidase.
This resorption process is gradual and silent, generally lasting between 12 and 18 months depending on the patient’s characteristics and the type of gel used. It leaves no residue in the tissues and does not alter the natural structure of the chin.
This complete reversibility is one of the main advantages of medical genioplasty. It allows the doctor to adjust the treatment according to facial changes, perform touch-ups if necessary, and, in case of dissatisfaction or correction needs, immediately dissolve the product using a hyaluronidase injection.
Thus, the patient benefits from a reliable and adaptable treatment that respects the fundamental medical principles of naturalness, adaptability, and reversibility.
It may happen, especially after a first injection, that the effects of hyaluronic acid seem to fade earlier than expected — sometimes between the 6th and 9th month. This situation, although unsettling for some patients, should not be interpreted as a treatment failure.
Several factors can explain a faster resorption of hyaluronic acid.
In this context, it is generally recommended to schedule a second session a few months after the first hyaluronic acid injection in the chin. This additional step helps reinforce the initially achieved projection, consolidate the stability of the result over time, and create a solid volumetric foundation, favorable to the success and longevity of future injections.
Personalized medical follow-up is essential to monitor progress, adjust the maintenance protocol, and ensure tailored care. In Geneva, an experienced doctor systematically offers this type of expert follow-up, providing each patient with continuous care and a harmonious long-term result.
The result of a hyaluronic acid injection in the chin is noticeable immediately after the session, but it naturally evolves over time. Understanding the different phases allows for anticipating possible touch-ups and appreciating the aesthetic transformation realistically.
It is reasonable to compare medical genioplasty to its surgical counterpart. Both approaches aim for similar goals — modifying the shape and projection of the chin — but their characteristics differ fundamentally.
Medical genioplasty is a flexible and non-invasive alternative to surgery. Its effects last on average between 12 and 15 months, and the procedure can be repeated as needed. The treatment leaves no scars, requires no downtime, and is fully reversible with a hyaluronidase injection if necessary. The result is gradual and can be adjusted over multiple sessions, allowing precise adaptation to the patient’s morphology and expectations. This approach is particularly suitable for patients who wish to try genioplasty without a permanent commitment, or who prefer to avoid major surgical intervention.
Medical genioplasty allows a progressive, subtle, and reversible improvement of the facial profile, without trauma or immobilization.
Surgical genioplasty involves an osteotomy, meaning a permanent modification of the chin’s bone structure, or the insertion of implants. Performed under general anesthesia, it requires a 2 to 3-week recovery period, with surgical risks such as infection, asymmetry, or implant displacement. This option may be indicated in severe cases of bone retrognathia, but it does not allow fine adjustments once the procedure is completed.
Certain anatomical features of the male face directly influence the longevity of the results after a medical genioplasty with hyaluronic acid :
Overall, the results of chin injections in men are known for their longevity, especially when the injection is performed deeply and the choice of hyaluronic acid is suited to tissue density. Personalized follow-up remains essential, however, to ensure the durability of the result and preserve the harmony of the male profile.
It is not necessary to systematically repeat a medical genioplasty every year. However, to maintain an optimal and lasting aesthetic result, most doctors recommend a maintenance session between 12 and 15 months after the first hyaluronic acid injection in the chin.
Follow-up and any touch-ups serve three main purposes: to prevent the complete loss of injected volume, to subtly adjust projection if necessary, and to prevent secondary asymmetries caused by partial resorption of the product. Some patients even prefer to anticipate as early as the 10th or 11th month to maintain a stable, harmonious, and perfectly defined profile.
Hyaluronic acid being a fully resorbable product, it is naturally metabolized by the body.
In some cases, the injection may slightly stimulate collagen production, leaving a subtle firming effect that persists after the gel disappears.
This reversibility is one of the major advantages of medical genioplasty: the treatment can be repeated to prolong the result, adjusted according to facial changes, or discontinued at any time, without permanent consequences.
Without maintenance sessions, the chin gradually returns to its original shape over the months. The perception of this return varies from patient to patient. Many quickly get used to their new profile and feel that the correction fades faster than it actually does.
