A well-defined oval is an asset of beauty and youth.
The « Jawline contouring », to be distinguished from the « Texas face », is a aesthetic-oriented medicine technique born in the USA used to create a more square and defined mandibular line.
Because of the influence of social networks, this treatment is increasingly popular among women and men aged 20 to 40.
Jawline contouring refers to a medical approach using hyaluronic acid injections aimed at improving the definition of the mandibular line, without exaggeration or radical transformation. It is not about creating a wider or more angular jaw, but rather about revealing the natural line of the oval by making it sharper, more even and better structured. This technique is suitable both for young patients with a poorly defined mandibular line and for mature patients whose oval has sagged over time. The objective is to achieve a subtle but noticeable improvement, while respecting the morphology of each face.
The aesthetic analysis is an essential part of the treatment process.
It is important to :
When the mandibular angle is less than 120 degrees, a narrow angle, the jaw appears slimmer and more angular, which gives the face a delicate expression, but sometimes insufficiently defined on the sides.
An angle greater than 130 degrees, a wide angle, gives the jaw a broader and more square appearance, which can weigh down the contours of the face and reduce the sharpness of the oval.
Jawline contouring is intended for women and men who wish to improve the definition of the mandibular line and the oval of the face. When the contours are not very marked, the lower part of the face can appear blurred, rounded or less structured, which alters the overall expression of the face.
Hyaluronic acid injections make it possible to reshape the mandibular line without surgery. This treatment offers a natural, harmonious result adapted to each morphology.
In women, the objective is not to masculinise the face, but to give it more structure and lightness. The aim is to refine the contour, redraw the jaw and strengthen the line of the oval while preserving softness and femininity. Many active women choose this treatment to achieve a more defined, more harmonious face and to gain confidence in their professional and social life.
In men, a well-defined jaw often evokes a structured and assertive face. A more marked mandibular line, a sharper angle and well-defined contours enhance masculine features. Conversely, a poorly defined and underdeveloped jaw can soften the face and make it less assertive.
In both cases, jawline contouring enhances the lower third of the face, increases contour definition and balances the profile, always respecting the natural shape of the face.
The main indications for jawline contouring are :
The definition of the jawline is achieved through the injection of hyaluronic acid. This procedure is often part of the 7/9 point Shape technique.
The injection is performed using a needle and a cannula. The product used is very firm and has volumising and/or lifting properties depending on the patient’s anatomy and the desired result.
The treated area extends from the mandibular angle to the chin. The latter is indeed a key element of the treatment : its projection and shape contribute to the definition of the mandibular line.
The quantity of product used is often significant, ranging between three and six syringes for women, and between three and fifteen for men.
Injections are not recommended if the bone structure is poorly developed at the level of the mandible. In this case, surgery is preferable as the quantity of product required would be too high.
Hyaluronic acid is today the most precise and safest tool to define the mandibular line without surgery. It is not a simple filler : when used with control, it performs a structural support function. It therefore makes it possible to restore deficient volumes, redefine the mandibular angle and improve the tension of the oval of the face.
During the injection, Doctor Romano does not only aim to restore an appropriate volume, but to reposition and support the tissues, taking into account the bone anatomy, the muscles and the quality of the skin. By strategically reinforcing certain key areas, a sharper, more defined jaw is created, with a better transition between the face and the neck. Hyaluronic acid also has a tightening effect, which helps to reduce the rounded or blurred appearance of the lower face without changing the patient’s natural features. Result : a reshaped jaw, harmonious, adapted to the patient’s morphology and always natural.
The amount of hyaluronic acid required for a jawline contouring varies from one patient to another. In his practice in Geneva, Doctor Romano always evaluates three elements : the natural structure of the jaw, the quality of the skin and the desired objective (light definition or more marked transformation). On average, the doctor uses between 2 and 4 syringes in women, as the objective is mainly to refine the oval, redefine the contours without weighing down the features, while respecting the elegance and femininity of the face. In men, 5 to 8 syringes are often required, particularly to reinforce the mandibular angle, project the jaw and create a structured line, a symbol of strength and character.
But beyond the number of syringes, the most important aspect remains the injection strategy. A successful jawline contouring does not simply consist of « filling », but of redrawing the mandibular line while taking into account the balance of the face, the chin and the cheekbones. It is this work of tensioning and repositioning the volumes that provides a natural, sharp and long-lasting result — without a swollen effect.
Before any injection, Doctor Romano meets each patient in her clinic in Geneva for a personalised consultation. This exchange is essential as it allows the evaluation of the natural structure of the face, the understanding of expectations, and above all the verification that jawline contouring is the most appropriate treatment. Doctor Romano analyses the mandibular line, the oval of the face, the quality of the skin and the overall balance of the face.
The doctor also checks for the absence of contraindications, such as pregnancy, breastfeeding, an active skin infection or certain autoimmune diseases.
During this first meeting, the doctor takes photographs that will serve as a reference to compare the result obtained. A personalised treatment plan is then proposed, along with a detailed quote.
On the day of the session, the injections take place in a dedicated medical space, discreet and comfortable. After careful cleansing and disinfection of the skin, the doctor proceeds with the hyaluronic acid injections. The product used contains an anaesthetic, which makes the treatment generally very well tolerated and only minimally painful.
The session lasts on average around twenty minutes. At the end of the treatment, the patient can immediately resume daily activities, without social downtime. “After” photographs are taken in order to visualise the immediate result and to monitor its evolution over time.
As a physician practising in Geneva, I have observed in my practice that jawline contouring with hyaluronic acid injections produces visible and long-lasting results when the technique is performed by an experienced doctor and the patient’s facial morphology is respected. This is also documented in the scientific literature : for example, the retrospective study by Raffaele Rauso et al., published in 2022, examined 36 patients (mean age ~45,7 years) treated with multiple syringes of hyaluronic acid injected into the lower third of the face ; they reported a satisfaction rate of 88,8 %. These patients reported improved definition of the mandibular angle and the mandibular line.
A more recent study, conducted by Adam Rivkin and published in Aesthetic Surgery Journal (2024), evaluated a hyaluronic acid gel to restore jaw definition ; the results showed a significant improvement in the mandibular line and an excellent safety profile.
Before treatment, the lower third of the face often lacks structure : the jaw is poorly defined, the mandibular angle is not clearly visible, the oval of the face is blurred and the transition between the chin and the neck is not well defined.
After injections performed by an experienced doctor, the mandibular line becomes visibly straighter and more defined, clearly outlining the lower contour of the face. The jaw angle appears sharper and better sculpted ; in men, this effect enhances the character and firmness of the jaw, while in women, it improves contour harmony without hardening the features. The oval of the face regains a clearer separation between the face and the neck, and the chin is more defined .
In studies, female and male patients have expressed a high level of satisfaction, associated with a very limited incidence of serious adverse effects.
However, the quality of the result depends not only on the injected product but also on the comprehensive analysis of anatomy (bone, skin, muscles, ligaments), the choice of volumes, the depth of injection and the facial morphology. When well performed, jawline contouring becomes a natural enhancement, not a visible addition — and this is precisely what my patients in Geneva are looking for : a subtle, elegant and enhancing result.
The price of jawline contouring mainly depends on the amount of product required to achieve a harmonious definition of the mandibular line. This treatment relies on the use of hyaluronic acid, the cost of which is 600 CHF per syringe. The number of syringes required varies depending on the patient’s morphology, tissue tone and the desired objective : subtle rebalancing or more pronounced reshaping.
During the initial consultation, a treatment plan is established according to these parameters. This evaluation makes it possible to accurately estimate the volume to be injected and, consequently, the overall cost. The approach is always personalised, consistent with the structure of the face and respectful of its natural proportions.

Jawline injections (hyaluronic acid) are effective for defining the jaw immediately and naturally. The results last between 12 and 18 months.
Hyaluronic acid injections to redefine the jawline are generally not very painful. A numbing cream can be applied to minimise discomfort. Some patients may feel slight pressure or tingling during the injection, but the procedure is quick and well tolerated.
To naturally enhance the jawline, you can :
• Practice facial exercises that target jaw and neck muscles.
• Maintain a stable weight to avoid fat buildup under the chin.
• Follow a balanced diet and stay well-hydrated.
• Do facial massages to boost circulation and firm the skin.
However, for more visible and lasting results, aesthetic treatments remain the most effective option.
The results of hyaluronic acid injections for jawline contouring last on average between 12 and 18 months, depending on the patient’s metabolism, the quality of the skin and the type of product used. Maintenance sessions are recommended to preserve the results.
The results are immediately visible after the session. The contour of the jaw is redefined and more harmonious. However, the final result can be observed after a few days, once the product has integrated into the tissues and any swelling has subsided.
The number of syringes depends on the patient’s anatomy and the desired result. In general, 2 to 4 syringes are required for a harmonious and natural reshaping of the jaw. A personalised assessment will determine the exact volume needed to achieve the desired aesthetic result.
