The definition of the facial oval is closely linked to a set of anatomical elements : the mandibular bone structure, chin projection, the position of fat tissues, skin density and skin tension. When one of these elements is insufficient, the oval may appear blurry, less structured and less defined.
In some young patients, this lack of definition results from a naturally subtle anatomy : a soft jawline, a discreet chin, a poorly visible mandibular angle or a soft transition between the face and the neck. This is not sagging, but a morphological characteristic.
In more mature patients, the loss of definition appears progressively with ageing. Bone resorption, fat loss, tissue sagging and skin thinning modify the morphology of the lower third of the face. The oval becomes rounder, jowls become visible, and the jawline loses sharpness. In both cases, injecting hyaluronic acid, using an approach adapted to the anatomy of each face, improves the definition of the oval either by creating a structure that is lacking or by restoring a structure that has been lost.
The jawline plays a central role in the harmony of the face, as it defines the architecture of the lower third of the face and ensures the transition between the midface and the lower face. A well-defined jawline is characterised by a clear but natural separation between the cheek, the jaw and the neck, without a harsh break or excessive volume.
Aesthetic criteria differ depending on the face.
In women, the preference is for a soft definition, with slightly rounded contours and a continuous line extending to the chin, without harshness or a sharply marked angle.
In men, it may be expressed through a more pronounced mandibular angle, a straighter line and a slightly projected chin base, emphasising masculine features.
But beyond gender, one principle remains constant : the balance of proportions, which is the principle of Beautiphication. A correctly positioned chin along the vertical axis of the face helps harmonise the whole, both from the front and in profile.
A well-defined jawline is not noticeable for its volume, but for its ability to enhance the entire face by bringing harmony and balance.
In young patients, hyaluronic acid is used to create or enhance a naturally soft jawline. This is sometimes referred to as jawline contouring, but the medical approach must remain measured and anatomically coherent. The goal is not to impose a standardised shape, but to adapt to the facial features while respecting proportions and identity.
A dense hyaluronic acid is used here, injected deeply in direct contact with the bone. This type of product has strong projection capacity and high resistance to compression. The hyaluronic acid compensates for the natural lack of structure in the jawline. The injection may also involve the mandibular angle, a key area where the separation between the face and the neck is defined.
When the chin is discreet or insufficiently projected, support is also provided there. A simple improvement in projection can transform the overall balance of the jawline and correct slight asymmetries. The desired result is a sharper, more balanced contour, without excessive volume or an artificially angular appearance. The modification should be noticeable yet discreet, visible yet natural.
In more mature patients, the objective is quite different. The aim is no longer to create a structure, but to restore the one that has been progressively altered over time. With ageing, the mandible loses bone density, fat tissues migrate downward, supporting ligaments loosen and the skin loses elasticity. The jawline becomes blurry, contours become rounder and the transition between the face and the neck fades. Hyaluronic acid injections in the facial oval then aim to replace this lost support.
Structural injection is performed with a firm hyaluronic acid, injected deeply in contact with the bone. The goal is no longer to create a shape, but to restore a natural support that ageing has gradually diminished. By giving back this support, the natural tension of the tissues is restored and the jawline is redefined without artificiality. The procedure always respects the facial dynamics, avoids any excess volume and favours morphological coherence.
In parallel with the loss of bone support, skin ageing plays a major role in the loss of definition of the oval. When the skin becomes thinner, loosens or loses density, even a good deep structure is no longer enough to maintain the tension of the lower third of the face. In these situations, Skinbooster-type hyaluronic acid provides an appropriate solution.
Injected into the dermis, this type of hyaluronic acid is not intended to create volume, but to strengthen the intrinsic quality of the skin. Thanks to its hydrating and biostimulating properties, it stimulates the synthesis of collagen and elastin, densifies the cutaneous matrix and gradually restores the thickness and firmness of the skin. The skin then tightens naturally, the contours become more defined and the jawline gains definition, without altering volumes. This dermal thickening induces a progressive and perfectly natural tightening effect. When combined with deep structural injections, the superficial injections act as a complement : in depth, support is restored, and on the surface, skin quality and tension improve.
This synergy makes it possible to obtain a global, coherent and long-lasting rejuvenation, respectful of the patient’s features and expressions.
The evolution of aesthetic standards has been strongly influenced by social media. The emphasis on perfectly structured profiles, pronounced jaw angles and sharp facial contours has contributed to popularising the idea of a defined oval, both in women and in men. Digital filters, direct-light portraits and three-quarter views have reinforced this awareness.
However, the requests expressed during consultations do not aim to reproduce these artificial visual effects. On the contrary, patients now seek measured, elegant and subtle results, far from caricature. Current techniques make it possible to respond to this expectation rationally, enhancing the natural structure of the face without transforming it. Hyaluronic acid reveals what exists; it does not reproduce what appears on screens.
The treatment of the facial oval with hyaluronic acid or Skinbooster injections always requires a prior consultation. Dr Romano performs a detailed morphological analysis, evaluating the mandibular structure, chin projection, skin thickness and tissue quality in order to determine the most suitable technique : deep structural injection or superficial dermal densification. The cost of the treatment depends on the amount of product needed and the type of hyaluronic acid used. A structurating syringe of hyaluronic acid intended to reshape or restore the jawline is offered at 600 CHF, while a Skinbooster syringe, injected into the dermis to improve skin density and reinforce the tightening effect, is offered at 400 CHF. At the end of the consultation, a personalised quote is provided.
This document is a truly tailor-made treatment plan, designed to respect each patient’s individual morphology and specifically meet their aesthetic objectives.
Hyaluronic acid helps to reshape and rejuvenate the facial oval by restoring lost volumes, improving skin tension and redefining the jawline. It corrects jowls, softens pronounced folds and restores harmony to the lower face.
The main signs include : the appearance of jowls, loosening of the jawline contours, loss of chin definition, pronounced marionette lines and nasolabial folds, and a face that appears less structured and less dynamic.
A volumising and structuring hyaluronic acid is used, specifically formulated to support, redefine and sculpt the facial contours. It is resorbable, biocompatible and suitable for facial remodelling.
Yes, when performed by an experienced physician, the result is natural, harmonious and adapted to the patient’s facial morphology. The goal is to enhance without transforming.
The injections are generally well tolerated. The products contain a local anaesthetic (lidocaine) and a numbing cream can be applied for added comfort. The session is quick and almost painless.
The session lasts between 30 and 45 minutes, including facial analysis, the personalised treatment plan and the injections.
The results are visible immediately after the session. The face appears more defined, firmer and more harmonious. The final result stabilises after 2 to 3 weeks.
The effects last on average between 12 and 18 months. A maintenance session may be suggested once a year depending on the patient’s profile and skin laxity.
Minor side effects are minimal : redness, slight swelling or temporary bruising. The treatment is contraindicated in cases of pregnancy, skin infection or active autoimmune disease.
Yes, for a more complete result, hyaluronic acid can be combined with Radiesse injections, botulinum toxin, thread lifts or radiofrequency, to enhance definition and firmness.
The price depends on the number of syringes required, the degree of sagging and the treatment plan. A quote is prepared during a personalised consultation.
