Jawline contouring redefines and projects the jawline through the strategic injection of high-density hyaluronic acid at key points: the jaw angle, the gonion and the chin. The result is a defined, balanced and rejuvenated profile.
Product is injected in the area behind the jaw (near the ear).

Filler is placed along the edge of the jaw.

It is applied to the chin to balance the profile.

Small amounts are used at specific points.

Full treatment from €595.
The final price depends on the area or areas to be treated, the product or cocktail used and the number of sessions the doctor recommends after the consultation. The first aesthetic medicine consultation costs €50 (deductible from your first treatment). We offer financing for extended treatments and treatment packages.

The treatment is carried out entirely in a medical office at Instituto de Benito in Barcelona or Madrid, in an outpatient session that is always planned and performed by a licensed aesthetic doctor. It consists of the following steps:

Before the treatment, you have a consultation with the aesthetic doctor at Instituto de Benito, who studies your case, listens to your goals, rules out contraindications and designs a personalized plan. The first aesthetic medicine consultation costs €50 (deductible from your first treatment).

When the doctor considers it necessary, a NESAI Derm ultrasound is performed in Barcelona to assess the skin before treating: dermis thickness, density, collagen, fibers and sun damage.

Preparation is simple: the area must be clean and free of creams. The doctor will tell you whether you should avoid any medication (anticoagulants, NSAIDs) in the days beforehand to minimize bruising, and will discuss with you any circumstances relevant to your safety.

The doctor disinfects the area, applies topical anesthesia if necessary and performs the microinjections with very fine needles, following the plan designed. The session is carried out entirely in the doctor's office and the patient returns to their routine immediately.

Results appear within the timeframe expected for the treatment, with a natural, harmonious finish. The doctor gives you home care instructions and schedules your follow-up appointments.


Jawline contouring is suitable for people in good general health who match any of these profiles. Final suitability is confirmed by the doctor after a personalized consultation.
When the facial contour is rounded and you are looking for jaw structure.
Facial sagging blurs the jawline over the years.
Combined with chin filler to define the lower third.
To rebalance the proportions of the lower third.
As part of a complete facial harmonization plan.
A well-defined jaw visually slims the neck area.
Patient safety comes before any aesthetic result. Jawline contouring should not be performed, or should be postponed, in the following cases:
| Contraindication | Reason |
|---|---|
| Pregnancy and breastfeeding | Injectable treatments are not performed during pregnancy or breastfeeding. |
| Active infection or lesion in the area | Herpes, folliculitis, dermatitis or open wounds: treatment is postponed until they have resolved. |
| Autoimmune disease or immunosuppression in an active phase | Requires individual assessment and, in some cases, a report from the specialist managing the case. |
| Anticoagulant treatment or a clotting disorder | Increases the risk of bruising; it is assessed with the prescribing doctor. |
| Known allergy to any of the components | Contraindicates the treatment. |
| Severe untreated bruxism | It is best to address it first, because it affects the result at the jaw angle. |
| Previous injections with non-resorbable material | We need to know what was applied before treating the area. |
Jawline contouring is safe when performed by a licensed doctor in an authorized center using approved medical products. Even so, every medical procedure has a profile of possible effects that it is only honest to share with you.
An aesthetic doctor from the IdB team designs the jawline contouring according to your facial morphology: round, oval, square or asymmetrical.

Jawline contouring is an advanced facial harmonization technique that defines the facial contour; Instituto de Benito plans it with an analysis of the full profile, not as an isolated treatment of the jaw angle.
At Instituto de Benito, patient safety comes before any aesthetic goal. We work with audited clinical protocols, medical products with medical CE marking and batch traceability, single-use instruments, dedicated aesthetic medicine rooms and personalized follow-up between sessions. We never delegate a medical-aesthetic procedure to non-medical staff.
Jawline contouring with high-density hyaluronic acid is one of the treatments recognized by the Spanish Society of Aesthetic Medicine (SEME) within facial harmonization. Its popularity has grown because of the "jawline" effect in demand on social media, but a sound clinical indication requires an analysis of the full profile (chin, neck, position of the hyoid bone) to achieve a balanced result rather than a caricatured one.
No. A thread lift repositions the tissues and creates a lifting effect, while hyaluronic acid adds volume and structure at the jaw angle and the chin. They are different but complementary treatments.
Hyaluronic acid redefines the contour by adding projection and volume (a more structural result), and lasts approximately 12 to 18 months. Thread lifts improve skin laxity and stimulate collagen (a tightening effect), and last 12 to 24 months. They are often combined for a more complete result.
The usual amount is 2 vials (one for each side of the jaw). In patients with a receding chin or who want more projection, 3 vials may be needed, including the chin area.
The effect usually lasts between 12 and 18 months, depending on the patient's metabolism, the type of hyaluronic acid used and lifestyle habits.
It is suitable for both. In men, the aim is a more marked, square jaw angle; in women, a contour that is more defined yet soft and balanced. The technique is adapted to the desired facial aesthetic.
Aesthetic medicine guidelines recommend spacing sessions 12 to 18 months apart to avoid overcorrection and maintain a natural result in the long term.
Yes. It is very often combined with chin treatments to correct “cobblestone chin” (uneven skin) and improve projection. It can also be combined with a thread lift or skin treatments.
It is a well-tolerated procedure. It is performed with a cannula or fine needle, and local anesthesia is usually applied or the product itself already contains lidocaine, which reduces discomfort.
Mild swelling or minor bruising may appear for 24-72 hours. In most cases, patients can return to their routine the same day.
Yes, the change is visible right away, although the final result is best appreciated after a few days, once the swelling goes down.
If it is performed correctly and with appropriate amounts, the result is natural. The risk of overcorrection arises when excessive volumes are applied or the treatment is repeated without proper control.
People with a poorly defined jaw, a lack of jaw angle, a receding chin or loss of firmness in the facial contour who are looking for an improvement without surgery.
Yes. Hyaluronic acid can be dissolved with hyaluronidase if necessary, which provides added safety.
It depends on the number of vials and the clinic. As a guide, full contouring with 2 vials usually costs around €500–700.
