Chin correction tailored to each face
Average amounts of hyaluronic acid used for chin correction
In clinical practice, hyaluronic acid volumes used for chin treatment generally fall within the following ranges.
- Slight correction (moderate projection of a receding chin) : 1 ml of hyaluronic acid is sufficient. This treatment aims to restore a little volume, often during a first injection.
- Profile harmonisation (projection and restoration of balance with the nose or lips) : 1 to 2 ml are generally needed. This is a targeted procedure within a non-surgical profiloplasty approach.
- Complete restructuring (definition, symmetry and jawline definition) : 2 to 3 ml are distributed across several strategic chin points. More than 2 ml most often concerns specific cases requiring an overall approach that also includes the mandibular angles and sometimes the facial oval.
Which criteria influence the amount required ?
Several clinical parameters guide the doctor's choice of volume.
- The extent of the concern to correct : a slightly receding chin requires a small volume. Marked retrogenia or clear asymmetry requires more substantial correction, sometimes performed in two stages to ensure a precise, natural result.
- Bone structure and soft tissues : a well-structured chin with pronounced bone structure already has a solid foundation, allowing improvement with a small volume of hyaluronic acid. Conversely, a flat chin requires larger amounts to redefine lower facial contours.
- The aesthetic goal : a slight improvement in the profile is generally treated with 1 ml. A more pronounced transformation — such as facial masculinisation or feminisation — often requires a larger volume to achieve the desired effect.
- Skin quality : on thin, firm skin, a small dose may suffice for a harmonious result. Thicker or looser skin requires a larger volume for a visible, lasting result.
Injection in one session or several stages ?
In some cases, the doctor deliberately chooses not to inject the entire planned amount of hyaluronic acid during the first session. A gradual approach may then be offered : an initial injection with a moderate volume (often around 1 ml), followed by reassessment after 15 days to a month, with a possible touch-up or additional product if necessary.
This strategy has several advantages. It allows tissue response to be observed, limits the risk of overcorrection and refines the final result to the millimetre. It is particularly indicated for a first non-surgical genioplasty injection or where great precision is required to restore profile balance and lower facial harmony.
The role of the hyaluronic acid used
The type of hyaluronic acid used plays a decisive role in successful non-surgical genioplasty. Products differ in their ability to provide projection, stability and cohesion. Chin treatment generally uses highly cross-linked hyaluronic acid to provide strong structural support ; sufficient cohesivity to retain shape and avoid migration ; and deep injection against the periosteum (bone), or subdermally depending on the precise indication.
Careful product selection and expert injection technique make it possible to achieve optimal results with a minimal amount of hyaluronic acid. In Geneva, this tailored approach ensures not only greater effectiveness but also increased safety and a natural result precisely suited to each facial morphology.
Can the amount be predicted in advance ?
The exact amount of hyaluronic acid required for non-surgical genioplasty can only be determined during consultation. The doctor performs a complete facial analysis, from the front and in profile, to assess precisely the volume needed for a harmonious, natural result.
A personalised quotation is always prepared before treatment. It specifies the planned amount of hyaluronic acid, expressed in syringes, and any additional options, such as a touch-up or treatment of other facial areas. This transparency provides patients with all the information needed for an informed decision in an atmosphere of trust and safety.
In Geneva, non-surgical genioplasty using hyaluronic acid injections is a reliable alternative to chin surgery. Adapting the injected amount to each facial morphology ensures a tailored result respecting profile balance and each face's individuality.
How hyaluronic acid needs change with age
The amount of hyaluronic acid needed for chin correction is never fixed : it changes with age and adapts to anatomical changes in the lower third of the face.
In young patients, injections most often have a structural aim. They correct a receding chin, improve projection or rebalance the profile. In these situations, volumes remain moderate : one 1 ml syringe generally suffices for a visible, natural and lasting result.
Needs change over time. Ageing involves gradual bone resorption in the chin, loss of soft tissue elasticity and skin sagging. The chin then appears less defined, the jawline fades and the cervicomental angle narrows.
In this context, hyaluronic acid injections aim to restore lost volume and overall support. Larger amounts are often needed, ranging from 2 to 3 ml, precisely distributed across several chin areas. In some cases, an overall lower facial approach — combining the chin, mandibular angles and jawline — provides a genuine rejuvenating effect.
Hyaluronic acid volume can therefore never be standardised. It must be adapted to each patient's age, tissue quality and aesthetic aims to preserve natural facial harmony and elegance.
Are two syringes necessary in every case ? Myth or reality ?
A frequent consultation question is : “Are two syringes of hyaluronic acid necessary to correct the chin ?” The answer is no. It depends on facial morphology, chin type and, above all, the aesthetic aim.
In the vast majority of cases, one 1 ml syringe suffices for a satisfactory result. This volume generally corrects mild to moderate retrogenia, improves chin projection and subtly structures the profile while preserving natural features.
Two syringes (2 ml) are reserved for specific situations : a very receding or poorly defined chin, a desire for more marked change — particularly among men — or chin treatment combined with other lower facial areas, such as the mandibular angles or facial oval.
The key is not the amount injected but the fit between volume, anatomy and the patient's wishes. A fine, harmonious face with delicate features often requires minimal correction. Patients with a masculine morphology or broader face usually need more product to achieve harmonious balance.
The myth of “2 syringes in every case” should therefore be abandoned. Every face is unique and requires a tailored strategy guided by the doctor's analysis and the desired aesthetic result.
What if one syringe is not enough ?
Sometimes the volume injected in a first session is insufficient for the desired effect. This does not mean treatment has failed, simply that a gradual approach is sometimes preferable.
A second session may then be offered after 15 days to a month. Splitting treatment has several advantages : it encourages better hyaluronic acid integration, allows the doctor time to assess tissue response, reduces overcorrection risk and enables millimetric adjustment for optimal results.
If the patient wishes and the doctor has the necessary experience, several syringes can also be injected during the first session. This flexibility adapts non-surgical genioplasty to the specific needs of each facial morphology while ensuring a natural, harmonious and safe result.
The doctor's role in assessing volume
Although questions about volume are natural, it is essential to remember that the doctor determines the amount to inject. Aesthetic wishes are of course considered, but the appropriateness of treatment rests on rigorous clinical analysis.
An experienced doctor assesses :
- Chin position in three dimensions.
- The proportions between the chin, nose and lips.
- Tissue condition (elasticity, density and symmetry).
- The impact of volume on facial balance.
Based on this overall assessment, the doctor determines the minimum amount needed to begin appreciating the result and the amount required for an optimal result. Following this analysis, the patient makes their choice.
