What does Jawline contouring involve ?
Jawline contouring is a medical approach using hyaluronic acid injections to improve jawline definition without exaggeration or radical transformation. It does not aim to create a wider or more angular jaw, but to reveal the natural jawline, making it sharper, more even and better structured. The technique is suitable for younger patients with an indistinct jawline and older patients whose lower facial contours have sagged over time. The aim is a subtle but noticeable improvement that respects each face’s anatomy.
How can you define your jawline ?
Aesthetic assessment is an essential part of treatment.
It is important to :
- Respect facial shape to create a jawline in harmony with the other features.
- Respect male–female differences and the principles of facial masculinisation and feminisation : men have a wide, square jawline, while women have a rounder, narrower one.
- Respect beautiPHIcation criteria : the distance from the corner of the mouth to the most projecting point of the chin is twice the distance from the mouth corner to the base of the nose.
- Determine the mandibular angle, which differs between men and women and must be adapted to each face.
When the mandibular angle is below 120 degrees, a narrow angle, the jaw looks slimmer and more angular, giving the face a delicate expression but sometimes insufficient lateral definition.
An angle between 120 and 130 degrees, a neutral angle, corresponds to balanced anatomy ; it allows a natural transition between the jaw and neck and creates a harmonious jawline.
An angle above 130 degrees, a wide angle, makes the jaw look wider and squarer, which can weigh down facial contours and reduce jawline definition.
Indications : why choose jawline contouring ?
Jawline contouring is for women and men wishing to improve definition of the jaw and lower facial contours. When contours are indistinct, the lower face may look blurred, rounded or less structured, changing the face’s overall expression.
Hyaluronic acid injections reshape the jawline without surgery. This treatment offers a natural, harmonious result tailored to each facial structure.
For women, the aim is to add structure and lightness without masculinising the face. Treatment refines contours, reshapes the jaw and strengthens the jawline while preserving softness and femininity. Many professionally active women choose it for a more defined, harmonious face and greater confidence in professional and social life.
For men, a well-defined jaw often conveys a structured, confident face. A stronger jawline, sharper angle and defined contours enhance masculine features. Conversely, an indistinct, 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 natural facial shape.
The main indications for jawline contouring are :
- Restoring definition to an indistinct jaw, rounded facial structure or recessed chin.
- Rebalancing the jawline and compensating for age-related volume loss.
- Adding structure to a male face that is too delicate or poorly defined.
How can you achieve a defined jawline without surgery ?
Jawline definition is achieved with hyaluronic acid injections. This is often part of the 7/9 point Shape technique.
Injections use a needle and cannula. The product is very firm and has volumising and/or lifting properties according to the patient’s anatomy and desired result.
The treated area extends from the mandibular angle to the chin. The chin is a key treatment element : its projection and shape contribute to jawline definition.
The amount of product is often substantial, ranging from three to six syringes for women and three to fifteen for men.
Injections are not recommended when mandibular bone structure is underdeveloped. Surgery is preferable in this situation, as too much product would be needed.
How can hyaluronic acid injections reshape your jaw ?
Hyaluronic acid is currently the most precise and safest tool for defining the jawline without surgery. It is more than a filler : when expertly used, it provides structural support. It restores deficient volume, redefines the mandibular angle and improves tension along the jawline.
During injections, Dr Romano aims to restore the right volume and reposition and support tissues, considering bone anatomy, muscles and skin quality. Strategically reinforcing key areas creates a sharper, better-defined jaw with an improved transition between face and neck. Hyaluronic acid also tightens tissues, reducing a rounded or indistinct lower face without changing the patient’s natural features. The result : a reshaped, harmonious jaw, suited to the patient’s anatomy and always natural.
How many syringes of hyaluronic acid are needed for jawline contouring ?
The amount of hyaluronic acid required for jawline contouring varies between patients. In her Geneva practice, Dr Romano always assesses three elements : natural jaw structure, skin quality and the desired goal (subtle definition or a more pronounced change). On average, she uses between 2 and 4 syringes for women, mainly to refine the jawline and redefine contours without weighing down features, while respecting facial elegance and femininity. Men often need 5 to 8 syringes, particularly to reinforce the mandibular angle, project the jaw and create a structured line conveying strength and character.
Beyond syringe numbers, injection strategy matters most. Successful jawline contouring involves more than “filling”, reshaping the mandibular line while considering the balance of the face, chin and cheekbones. This tightening and repositioning of volume produces a natural, sharp and lasting result — without puffiness.
What happens during a jawline contouring session
Before any injections, Dr Romano welcomes each patient to her Geneva practice for a personalised consultation. This discussion is essential to assess natural facial structure, understand expectations and establish whether jawline contouring is the most appropriate treatment. Dr Romano analyses the jawline, lower facial contours, skin quality and overall facial balance.
She also checks for contraindications, such as pregnancy, breastfeeding, active skin infection or certain autoimmune diseases.
At this first appointment, photographs are taken as a reference for comparing results. A personalised treatment plan and detailed quotation are then proposed.
On treatment day, injections take place in a dedicated, discreet and comfortable medical setting. After thorough skin cleansing and disinfection, Dr Romano injects hyaluronic acid. The product contains anaesthetic, making treatment generally very well tolerated and minimally painful.
A session lasts around twenty minutes. Afterwards, patients can immediately resume daily activities without social downtime. “After” photographs document the immediate result and track its development over time.
Results : before / after jawline contouring
As a doctor practising in Geneva, I have observed that hyaluronic acid jawline contouring produces visible, lasting results when performed by an experienced doctor who respects the patient’s facial structure. This is also documented in 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 several syringes of hyaluronic acid in the lower third of the face ; they reported a satisfaction rate of 88,8 %. These patients described improved definition of the mandibular angle and jawline.
A more recent study by Adam Rivkin, published in Aesthetic Surgery Journal (2024), assessed a hyaluronic acid gel for restoring jaw definition ; results showed significant improvement in the jawline 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, lower facial contours are indistinct and the transition between chin and neck lacks definition.
After injections by an experienced doctor, the jawline becomes visibly straighter and stronger, clearly outlining the lower face. The jaw angle looks sharper and better defined ; in men, this reinforces jaw strength and character, while in women it improves contour harmony without hardening features. The jawline regains a clearer separation between face and neck, and the chin is better defined .
In studies, both women and men expressed high satisfaction, with a very low incidence of serious adverse effects.
However, result quality depends on the injected product and a complete anatomical assessment (bone, skin, muscles, ligaments), volume selection, injection depth and facial structure. Expertly performed, jawline contouring becomes a natural enhancement rather than a visible addition — precisely what my Geneva patients seek : a subtle, elegant, flattering result.
What is the price of Jawline Contouring ?
In Geneva, hyaluronic acid injections for jawline contouring cost 600 CHF per syringe.
The price of jawline contouring depends mainly on the amount of product needed for harmonious jawline definition. Treatment uses hyaluronic acid, costing 600 CHF per syringe. Syringe numbers vary with the patient’s anatomy, tissue tone and goal : subtle rebalancing or more pronounced reshaping.
During the initial consultation, a treatment plan is established according to these factors. This assessment precisely estimates the volume to inject and therefore the overall cost. The approach is always personalised, consistent with facial structure and respectful of natural proportions.
