WHAT HAPPENS DURING A CHIN HYALURONIC ACID INJECTION SESSION ?

Last updated : 7 June 2026

Hyaluronic acid injections in the chin are an increasingly requested aesthetic medical procedure, both to rebalance the profile and to refine the lower third of the face. Although quick and minimally invasive, the procedure remains technically demanding and subject to strict medical oversight.
Here is a precise, step-by-step description of a session in a medical practice in Geneva.

The preliminary medical assessment

Before any chin injection, a thorough medical consultation is essential. This allows the doctor to objectively analyse overall facial morphology, chin position and projection, facial symmetry and skin tissue quality. Examination considers several essential criteria : chin alignment in profile, lower facial proportions, the relationship between the nose, lips and chin, and the cervicomental angle defining the junction between chin and neck. The doctor also examines any asymmetries or hollows that could affect facial harmony.
This first meeting also gives patients the opportunity to express their expectations. The doctor's role is to compare these wishes with anatomical realities while always preserving balance and natural features. This tailored approach is essential for a satisfactory, safe aesthetic result.
Following consultation, a personalised treatment plan is established. It specifies the areas to correct, the most suitable hyaluronic acid type, the proposed amount, overall cost and any additional sessions, whether for touch-ups or maintenance. 

Before the session : how to prepare for chin injections ?

A hyaluronic acid injection session begins well before the procedure itself. Certain recommendations should be followed in the preceding days to ensure safe, precise and optimal treatment.

What should you do before injection ? 

  • Keep your skin well hydrated in the days before the session : supple skin tissue responds better to injection and improves product integration.
  • Tell your doctor about all medical history, medication use, anticoagulant treatment and known allergies.
  • If you bruise easily, preventive arnica may be considered a few days before the procedure (with the doctor's agreement).

Arriving rested, without make-up and relaxed also contributes to successful treatment in a calm, safe medical setting.

What is best avoided 

  • Anti-inflammatory medicines (aspirin and ibuprofen) should be avoided for 3 to 5 days before injection because they increase bleeding or bruising risk.
  • Drinking alcohol or eating very salty or spicy foods in the 24 hours before treatment is discouraged to limit inflammation.
  • Also avoid supplements that thin the blood (omega-3, vitamin E and ginkgo biloba) during the week before the session.

Medical preparation for the session

On the day of injection, the session begins with thorough chin disinfection according to medical aseptic protocols. The face is cleaned with antiseptic solution and then carefully dried using sterile materials.
If necessary, anaesthetic cream can be applied around twenty minutes before the procedure. In most cases this is unnecessary, as the latest hyaluronic acids already contain lidocaine, an integrated anaesthetic making injection virtually painless.
The doctor then marks the injection points with a skin-marking pencil, following the anatomical landmarks established during the preliminary consultation.

Chin injection session 

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

  • Needle injections : these provide great precision and deep injection, particularly against the periosteum (chin bone), when structural support is the aim.
  • Cannula injections : these encourage more uniform product distribution and reduce bruising risk, making them particularly suitable for gently smoothing and sculpting the area.

The doctor injects hyaluronic acid slowly, strictly respecting anatomical tissue planes. The aim is to add volume or support precisely where needed without overcorrection. Gentle massage is often performed to distribute the product evenly.
Depending on needs, treatment can target forward chin projection, asymmetry correction, improved jawline definition or reduction of a hollow or pronounced dimple.

How long does a session last ?

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

  • 10 to 15 minutes for discussion before injection, reviewing the established plan and confirming the procedure.
  • 5 minutes for the injection itself.
  • 5 minutes for post-procedure assessment, discussion with the patient and recommendations.

The procedure must not be rushed. It should be performed calmly, with careful assessment of the final result. No time off work or social downtime is needed : activities can resume immediately afterwards.

Why is choosing the doctor essential for chin injections ?

Correcting a chin with hyaluronic acid injections involves more than adding volume. It is a medical procedure requiring detailed understanding of facial anatomy and rigorous mastery of injection techniques.

  • An anatomically sensitive area : the chin is a complex junction near the terminal branches of the mental nerve, the anterior facial vein and the mentalis muscle. Injecting without precise knowledge of these structures can cause unattractive results or, rarely, functional complications.
  • Expert aesthetic assessment : beyond technique, the doctor must assess ideal chin projection according to profile, interpret lateral symmetry axes, adapt the procedure to facial shape (oval, square, long or round) and favour a moderate, gradual and reversible approach. An experienced doctor injects just enough in the right place without freezing features. Treatment is a precision procedure that respects facial identity.

A safe, controlled and reversible protocol

When performed by an experienced doctor, hyaluronic acid chin injection is considered reliable and safe, with an extremely low complication rate. The product is biodegradable, fully biocompatible and reversible, ensuring controlled care without risk to the body.
Results are immediately visible and last an average of 12 to 18 months, depending on the hyaluronic acid selected, the injected area and each patient's metabolism. An annual maintenance session is generally recommended to preserve optimal chin definition and a well-structured jawline. This gradual, personalised approach maintains a natural, harmonious and lasting result without surgery.

Key figures on hyaluronic acid chin treatment

To better understand the actual impact of hyaluronic acid chin injections, here are figures from clinical practice and recent aesthetic medical studies :

  • In 2024, chin treatment accounts for around 35 % of requests for facial profile harmonisation, just behind nose injections.
  • In 80 % of cases, the amount of hyaluronic acid used is between 1 and 1,5 ml, distributed across several anatomical support points to ensure a balanced, natural result.
  • Satisfaction after one month exceeds 92 %, with results considered structuring, discreet and faithful to facial proportions.
  • Touch-ups are needed in around 20 % of cases. These mainly involve small adjustments (an additional 0,2 to 0,3 ml) to optimise symmetry and projection.
  • The average duration of a complete session, including consultation, is around 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 injections are safe, well-established and increasingly popular, meeting growing demand for gentle, non-surgical aesthetic corrections.
