The importance of proportions in jawline definition
The jawline is not an isolated area : it forms part of a set of proportions defined by the relationship between the chin, mandibular line, cheekbones and neck. Reshaping therefore requires thorough understanding of these anatomical relationships. Chin length and projection, the mandibular angle and balance between midface width and the base of the face directly influence jawline perception.
Precise assessment identifies areas requiring projection, height adjustment or subtle correction. Some patients have a short chin, weak mandibular angle or insufficient definition between cheek and jaw. Others have natural asymmetry that an expertly performed technique can rebalance. Reshaping therefore considers lines, volume and angles to create a harmonious lower face balanced with other facial structures.
Hyaluronic acid to reshape the jawline
Hyaluronic acid is essential for jawline reshaping. The gels used are fairly firm, cross-linked and cohesive, allowing sharp lines and precise mandibular sculpting. The aim is to build support and improve lateral facial definition rather than visibly increase volume.
Injections may target key areas : the mandibular line, for even, harmonious definition ; the mandibular angle, to reinforce the junction between cheek and neck ; the chin, to improve its shape, height or projection
The technique often places product deeply against bone, producing a sharp, stable and natural result. This three-dimensional work subtly changes lower facial shape without excess.
Reshaping the jawline in women and men
Jawline redefinition meets different aesthetic requirements according to the patient’s profile. Women most often seek a balanced but delicate mandible, subtly refined with a smooth transition between cheek and jaw. Many men prefer a more structured line, stronger angle and clearer lateral definition.
The aim is to respect facial anatomy and enhance natural lines rather than masculinise or feminise a face. An excessively square female face would lose softness, while an overly round male face might lack character. The art lies in adapting treatment to the patient’s identity, personality and expectations.
Profiloplasty and jawline definition
The profile plays a decisive role in jawline perception (medical profiloplasty). Insufficient chin projection, a poorly defined neck or an indistinct jaw–neck junction can reduce overall definition even from the front. Reshaping therefore requires a 360° facial assessment including profile and three-quarter views.
Subtle chin projection is sometimes enough to reshape the entire lower face. Improving the jawline can also create the impression of a longer neck, a more slender face and better-balanced proportions. Considering the profile allows consistent, harmonious correction fully adapted to the patient’s anatomy.
Sculptra to structure the jawline
In some patients, jawline redefinition relies more on improved tissue quality than projection. Sculptra, a collagen stimulator, acts gradually by reinforcing the dermal network and restoring tension and cohesion to lower facial tissues.
This deep biostimulation improves natural skin support, making the jawline visibly sharper even without volumising fillers. Sculptra may be used alone or combined with hyaluronic acid when skin lacks firmness or the jawline needs stronger structural support.
Laser photorejuvenation : improving skin quality around the jawline
Structural correction alone is insufficient for true jawline reshaping : skin quality is equally decisive. Laser photorejuvenation improves skin density, radiance and firmness, reduces irregularities and stimulates collagen production.
By strengthening the skin, it increases contrast between the mandibular line and surrounding tissues, defining the lower face more sharply. This treatment is particularly indicated when thin, loose or uneven skin blurs the jawline.
Personalised care in aesthetic medicine
Reshaping the jawline requires detailed understanding of each patient’s anatomy. Some need treatment centred on the chin, while others need reinforcement of the mandibular line. For some, projection is the priority ; for others, refinement or correction of natural asymmetries.
A personalised treatment plan produces a harmonious, balanced and natural result. The aim is to reveal facial structure, refine proportions and enhance contours rather than transform the face.
What is the price of injections to reshape the jawline ?
Prices of jawline reshaping treatments vary according to the technique used and degree of correction desired.
Hyaluronic acid injections cost 600 CHF per syringe ; the quantity required is determined during consultation according to the areas treated.
Sculptra, which strengthens skin density and natural tissue support, costs 900 CHF per vial.
A laser photorejuvenation session to improve skin firmness and quality costs 500 CHF.
Every treatment plan is tailored to ensure a natural, harmonious and lasting result
In a study involving 35 people, calcium hydroxylapatite injections were used to redefine the jawline. One year after treatment, physicians still observed an improvement in 81% of participants. These results concern the product studied. The absence of a control group prevents comparison with other treatments.
In a study involving 36 women, hyaluronic acid injections aimed to improve jawline definition. The choice of gel and injection areas was tailored to facial anatomy. The vast majority of participants reported being very satisfied with the result. This study describes a personalised correction of the contours of the lower third of the face, without comparison with another method.
A review of chin and jawline injections explains how to improve definition in the lower third of the face. Depending on individual needs, treatment can increase the projection of a receding chin, address jowls or better define the jawline. The choice of product and quantities depends on anatomy and the desired result. This approach can redefine the jawline without surgery when laxity is moderate.

Frequently asked questions
Why does the jawline change over time ?
With age, skin loses elasticity, collagen and hyaluronic acid. Volume descends, skin laxity develops and contours become less distinct, causing jowls and lost jaw definition.
How can the jawline be reshaped without surgery ?
Hyaluronic acid injections restore volume, redefine mandibular contours, correct jowls and rebalance the chin line. Depending on the case, treatment may be combined with lifting threads, radiofrequency or Radiesse injections.
Which treatment should you choose to redefine the jaw and facial contours ?
Volumising hyaluronic acid is the most widely used treatment to structure and support the jawline. Radiesse may also stimulate collagen synthesis and reinforce tightening.
Who is this treatment for ?
It suits men and women from 30-35 years with mild to moderate sagging, lost facial definition or a desire for a more sculpted, harmonious and youthful appearance.
Is the result natural ?
Yes. The aim is to restore facial structure, balance and youthfulness while respecting anatomy and natural expression rather than transform the face.
How long does the session last ?
A session lasts between 30 and 45 minutes, including facial assessment, explanation of the treatment plan and injections.
When do results become visible ?
Results are visible immediately and improve over the following weeks as the product integrates into tissues. The final result appears between 2 and 4 weeks.
How long does the result last ?
Depending on the product used (hyaluronic acid, Radiesse), results last 12 to 18 months. Maintenance may be performed once a year.
Is treatment painful ?
Injections cause little pain : products contain anaesthetic and anaesthetic cream may be applied. Discomfort is minimal.
Are there side effects ?
Mild redness, swelling or small bruises may occur but generally disappear within a few days. There is no social downtime.
