Jawline contouring with hyaluronic acid for men in Geneva
“Jawline contouring” means redefining the jaw's outline. Currently popular, particularly on social media, this aesthetic approach harmonises the lower facial third. It is suitable for men and women, with goals depending on individual expectations. In men, the aim is usually to strengthen mandibular structure by emphasising angles, slightly broadening the jaw and projecting the chin. The goal is a clearer, straighter line from the mandibular angle to the chin. Once achievable only through surgery, this technique is now performed in the medical practice using hyaluronic acid injections.
Male aesthetic criteria
The aesthetically ideal male lower facial third is prominent, with a broad, square chin and a well-defined, projected, angular mandibular angle of approximately 120° (the male angle is slightly narrower than the female angle).
The masculine appearance of the face is largely determined by lower facial structures.
- The chin : the chin is essential to the lower facial third and increases attractiveness. Its shape, projection, rotation and height are determined by bone structure, muscles and fat. These can be modified with hyaluronic acid injections.
- The jawline : the jawline extends from the chin to the mandibular angle. Poor definition can be genetic or age-related, as bone resorbs and tissues descend over time, blurring the jawline.
- The mandibular angle : a prominent mandibular angle is important for a youthful, attractive lower face. Its projection gives the face character.
Which men choose jawline contouring ?
Patients seeking jawline treatment have varied profiles. Some have poorly defined facial contours and soft features they wish to structure. Others already have good definition but want to emphasise particular angles. Requests vary with age : after 40, restoring facial contours and correcting skin laxity for a more dynamic appearance is more common. Younger patients often seek more targeted, pronounced aesthetic changes with a more defined jawline.
Jawline contouring may be indicated for :
- Men seeking a more defined jaw and better projection of the lower facial third.
- Patients with a poorly defined jawline or insufficient chin projection.
- Men with jaw asymmetry or irregular mandibular contours.
- Patients over 40 wishing to compensate for age-related loss of facial contour definition.
- People seeking a nonsurgical alternative for improving facial contours.
- Men whose profession or public image places particular importance on facial appearance, including models, athletes, actors, content creators and media-facing professionals.
What happens during a session
hyaluronic acid injections
for the male jaw
Jawline treatment with hyaluronic acid is a quick, noninvasive procedure performed in the practice. An initial consultation is essential to assess facial structure, understand expectations and establish a suitable strategy. Dr Romano also explains treatment details and expected results. Injections are then performed in a single, generally short session.
Product choice depends on the areas treated : more structural hyaluronic acids redefine jaw angles or the chin, while softer products smooth the jawline. Depending on the indication, injections use a needle or cannula, superficially or deeply.
A needle is used to inject deep boluses of hyaluronic acid against the bone to support structures.
A cannula is used to add volume and definition. The product is injected into deep subcutaneous tissue.
The injection session lasts approximately fifteen minutes with no social downtime ; normal activities resume immediately.
Male jawline, the results
The results of hyaluronic acid jaw injections in men are :
- A more defined mandibular angle : hyaluronic acid injections at the mandibular angle create clear definition between neck and face, giving the face a sense of strength.
- A straighter jawline : hyaluronic acid injections along the jawline define it and lift sagging tissues.
- A broad, square chin : hyaluronic acid chin injections improve facial proportions and give the lower face a slightly ‘more athletic’ character.
The number of syringes varies with the desired result and individual anatomy : three to fifteen facial syringes may be needed. Results last approximately one year.
How long do the effects last on average ?
Results are visible immediately, although approximately ten days are needed to assess the final result once the product has fully integrated. Results generally last between ten and twelve months.
What risks can occur after injections ?
Recovery is straightforward and requires no social downtime. Mild side effects may occur, including swelling, redness or small bruises. These are temporary and resolve spontaneously within a few days. As hyaluronic acid occurs naturally in the body, side effects remain limited.
Cryolipolysis of the double chin
in men
In some patients, localised double chin fat reduces jawline definition. Cryolipolysis is a noninvasive technique that reduces these deposits through cooling, without surgery.
By specifically targeting this area, treatment makes the jaw more visible. It integrates into comprehensive lower facial treatment, particularly alongside hyaluronic acid injections, for a clearer, more structured jawline.
Results develop gradually over three months, with lasting improvement in definition.
Hyaluronic acid for the male jaw : prices in Geneva
Male jawline hyaluronic acid injections cost 600CHF per syringe, with personalised planning according to facial structure and aesthetic goals. A precise quotation is provided at the initial consultation. Cost depends on the desired result and amount of product needed. In practice, several syringes are often required for harmony. Treatment is entirely adapted to individual facial and bone structure.
Depending on anatomy, several syringes may be needed for optimal results. Treatment usually takes place over two sessions a few weeks apart, building volume gradually and harmoniously.
During the first year, initial treatment may require many syringes to fully structure the jaw, making the initial cost higher. Thereafter, just one or two syringes generally suffice for annual maintenance. Maintaining results therefore requires less product and more widely spaced sessions, reducing long-term cost.
WHAT THE STUDIES SAY
A review of male facial anatomy describes a generally more angular jaw, proportions that differ from those of the female face and often more developed musculature. These characteristics should be considered when selecting treatment areas, quantities of product to inject and techniques to use. Treatment aims to reduce the signs that concern the patient while preserving his features.
A study compared filler injections performed in 100 men and 100 women of similar age. Men more often received jaw injections. In the cheeks, injection points were not distributed in the same way in men and women. These differences show that treatment areas vary according to facial anatomy and the intended result. This study describes the treatments performed.
Frequently asked questions about the male jawline
How do you practise mewing correctly ?
Mewing involves placing the tongue against the palate, with its whole surface resting against the roof of the mouth. Teeth should be lightly together without force, lips closed and breathing through the nose. This posture should be maintained as often as possible, even at rest.
Does mewing really work ?
Mewing can improve jaw posture and slightly strengthen facial muscles. However, results are gradual and limited, particularly in adults. Aesthetic medicine techniques remain the most effective option for significant, rapid changes in jaw definition.
What is mewing ?
Mewing means adopting correct tongue posture by placing the tongue against the palate. It aims to improve facial definition, encourage better breathing and strengthen facial muscles. It is based on orthotropic principles.
What are the possible side effects of mewing ?
Mewing is generally safe, but incorrect practice can cause :
• Jaw muscle pain.
• Neck or facial tension.
• Temporary problems associated with poor tongue posture.
Which aesthetic medicine techniques improve jaw definition in men ?
Several options can strengthen the jaw :
• Hyaluronic acid injections to sculpt and redefine contours.
• Cryolipolysis to reduce submental fat.
These treatments provide immediate, natural results.
Can hyaluronic acid injections strengthen and broaden the jaw angles for a more masculine appearance ?
Yes, hyaluronic acid injections strengthen and broaden jaw angles, creating more defined, masculine contours.
