HOW DOES A HYALURONIC ACID INJECTION SESSION FOR THE CHIN TAKE PLACE ?

Hyaluronic acid for the chin in Geneva

Hyaluronic acid injection in the chin is an increasingly requested aesthetic medical procedure, both to rebalance a profile and to refine the lower third of the face. While it is a quick and minimally invasive procedure, it remains technical and strictly regulated.
Here is, step by step, the precise course of a session in a medical office in Geneva.

Preliminary medical analysis

Before any chin injection, a thorough medical consultation is essential. This step allows the physician to objectively analyze the overall facial morphology, the position and projection of the chin, facial symmetry, and the quality of the skin tissues. The examination considers several essential criteria : chin alignment in profile, proportions of the lower third, the relationship between the nose, lips, and chin, as well as the cervico-mental angle defining the junction between the chin and the neck. The physician also examines any potential asymmetries or depressions that could disrupt facial harmony.
This first meeting is also the time for the patient to express their expectations. The physician’s role is then to reconcile the request with anatomical realities, always ensuring the balance and naturalness of the features. This tailored approach is essential to guarantee a satisfactory and safe aesthetic result.
At the end of the consultation, a personalized treatment plan is established. It specifies the areas to be corrected, the most suitable type of hyaluronic acid, the planned quantity, the overall cost, and any additional sessions, whether for a touch-up or maintenance.

Before the session : how to properly prepare for a chin injection ?

A hyaluronic acid injection session begins well before the procedure itself. To ensure a safe, precise, and optimal treatment, certain recommendations should be followed in the days prior.

What to do before the injection ? 

  • Keep your skin well hydrated in the days leading up to the session : supple skin responds better to the injection and improves product integration.
  • Inform your physician of any medical history, medication use, anticoagulant treatment, or known allergies.
  • If you are prone to bruising, preventive use of arnica can be considered a few days before the procedure (in agreement with the physician).

Arriving rested, makeup-free, and relaxed also contributes to the success of the treatment, in a calm and safe medical setting.

What is best to avoid 

  • Anti-inflammatory medications (aspirin, ibuprofen) should be avoided 3 to 5 days before the injection, as they increase the risk of bleeding or bruising.
  • It is advised to avoid alcohol or highly salty or spicy foods in the 24 hours preceding the procedure, to limit inflammation.
  • Also avoid blood-thinning supplements (omega-3, vitamin E, ginkgo biloba) in the week preceding the session.

Medical preparation for the session

On the day of the injection, the session begins with a thorough disinfection of the chin area, carried out according to medical asepsis protocols. The face is cleaned with an antiseptic solution and then carefully dried using sterile equipment.
If necessary, a topical anesthetic cream can be applied about twenty minutes before the procedure. In most cases, this is unnecessary because the latest-generation hyaluronic acids already contain lidocaine, an integrated anesthetic that makes the injection almost painless.
The physician then marks the injection points using a dermographic pencil, following the anatomical landmarks defined during the prior consultation.

Chin injection : a technical procedure

Hyaluronic acid injection in the chin is a quick procedure : the session generally lasts a few minutes, depending on the areas treated (chin alone or combined correction with other parts of the face) and the degree of projection desired.
Two main techniques can be used :

  • Needle injections : they allow high precision and deep injection, particularly in contact with the periosteum (the chin bone), when the goal is to provide structural support.
  • Cannula injections : they facilitate a more even distribution of the product and reduce the risk of bruising, making them particularly suitable for gently smoothing and sculpting the area.

The physician injects the hyaluronic acid slowly, strictly respecting the anatomical planes. The goal is to add volume or support exactly where needed, without overcorrection. A light massage is often performed to distribute the product evenly.
Depending on the needs, the treatment can target anterior projection of the chin, correction of asymmetry, enhancement of the jawline definition, or reduction of a pronounced depression or dimple.

What is the duration of a complete session ?

Although hyaluronic acid injection for the chin is a quick procedure technically, it takes place within a structured medical framework, requiring an appropriate amount of time.
Most sessions last between 20 and 30 minutes, divided as follows :

  • 10 to 15 minutes of pre-injection discussion, review of the established plan, and validation of the procedure.
  • 5 minutes for the injection itself.
  • 5 minutes for post-procedure check, discussion with the patient, and recommendations.

The procedure should not be rushed; it must be carried out calmly, with careful evaluation of the final result. There is no need for time off work or social avoidance : normal activities can be resumed immediately afterward.

Why is the choice of physician essential for a chin injection ?

Correcting a chin with hyaluronic acid injection is not simply about adding volume. It is a medical procedure that requires a precise understanding of facial anatomy and rigorous mastery of injection techniques.

  • A high-stakes anatomical area : the chin is a complex crossroads, near the terminal branches of the mental nerve, the anterior facial vein, and the mentalis muscle. Injecting without precise knowledge of these structures can lead to unsightly results or, in rare cases, functional complications.
  • Expert aesthetic assessment : beyond the technique, the physician must be able to evaluate the ideal chin projection according to the profile, read the lateral symmetry axes, adapt the procedure to the shape of the face (oval, square, long, round), and favor a moderate, progressive, and reversible approach. An experienced physician will inject just the right amount, in exactly the right place, without freezing the features. The treatment is a precision intervention, respectful of the face’s identity.

A safe, controlled, and reversible protocol

When performed by an experienced physician, hyaluronic acid injection in the chin is considered a reliable and safe procedure, with an extremely low complication rate. The product used is biodegradable, fully biocompatible, and reversible, ensuring controlled management without risk to the body.
Results are visible immediately and typically last between 12 and 18 months, depending on the type of hyaluronic acid chosen, the area injected, and each patient’s metabolism. To maintain optimal chin definition and a well-structured jawline, an annual maintenance session is generally recommended. This progressive and personalized approach allows for a natural, harmonious, and long-lasting result, without resorting to surgery.

Key figures on chin treatment with hyaluronic acid

To better understand the real impact of hyaluronic acid injection in the chin, here are some figures from clinical practice and recent studies in aesthetic medicine :

  • In 2024, chin treatment accounts for approximately 35 % of facial profile harmonization requests, just after nose injections.
  • In 80 % of cases, the amount of hyaluronic acid used ranges between 1 and 1.5 ml, distributed across several anatomical support points to ensure a balanced and natural result.
  • The satisfaction rate at one month exceeds 92 %, with results considered structuring, subtle, and faithful to the facial proportions.
  • Touch-ups are necessary in approximately 20 % of cases. They mainly involve small adjustments (0.2 to 0.3 ml additional) to optimize symmetry and projection.
  • The average duration of a complete session, including the consultation, is approximately 40 minutes.
  • Fewer than 2 % of patients experience mild side effects, such as bruising or prolonged swelling, which resolve spontaneously within a few days.

These data confirm that chin injection is a safe, well-standardized procedure, and a growing practice, meeting the increasing demand for gentle, non-surgical aesthetic corrections.
