Jawline

Information on Dermal Fillers for the Jawline

Dermal filler treatment for the jawline is a medical procedure that involves injecting a gel-like substance to add volume and alter the contours of the jaw area. The shape and definition of the jawline can vary significantly between individuals due to genetic factors and the natural aging process.

The Procedure
During the procedure, a dermal filler product is injected at specific points along the mandible (the lower jaw). This adds volume to the tissue, which can create a more defined or augmented appearance of the jawline’s structure.

About Dermal Filler Products

The dermal fillers used for this procedure are typically composed of a synthetic hyaluronic acid gel. Hyaluronic acid is a substance that is also found in the human body, where it helps to hydrate the skin and lubricate joints. When used as a dermal filler, the product provides volume in the area where it is injected. All dermal fillers are regulated medical devices and carry potential risks.

The administration of dermal fillers is a medical procedure and should only be performed by a qualified health practitioner. A thorough consultation is required to assess your individual anatomy and determine if this treatment is appropriate for you, as well as to discuss potential risks and complications.

Benefits of jawline Filler:
  • Define the jawline and sculpt the face
  • Reduce the visibility of the submental fat
  • Create structural support that is lost during the ageing process
What is involved?

Before starting the jawline filler treatment, our team will thoroughly clean the area and apply a topical anaesthetic for your comfort. The treating doctor or nurse will then do a series of injections into the area using our bespoke technique, which means we inject the fillers to enhance your natural features.

Your filler appointment will take about 45 minutes from start to finish. You can return to your regular activities after the injections are completed. While this cosmetic treatment involves little to no downtime, you still need to take measures following the procedure. Our highly experienced team will discuss the aftercare required to ensure a smooth recovery.

At One Cosmetic, we use only the most advanced range of Hyaluronic acid dermal fillers available in the Australian market. These products also contain lidocaine, which means that the treated areas are numbed simultaneously during treatment, improving the overall treatment experience for the patient. Your injector will then gently massage the fillers to soften the product.

Risks
As always, there is risk involved with every treatment. At One Cosmetic we like our patients to be aware of risks and be well educated on the treatments they are undergoing. The risks associated with lip filler treatments are:
  • This occurs when filler is injected into or around an artery, causing blood flow to be reduced or stop. Skin may look pale (blanched) and start to turn blue over a period of 24 hours. This is usually painful and, if untreated, the skin may start to ‘die’ and turn black.
  • Filler migration
  • Skin discolouration
  • Bacterial infection
  • Viral infection
  • Ulceration of the skin where you were injected
  • Lumps (nodules) forming under the skin
  • Allergic reaction
  • Permanent disfigurement and scarring
  • Haematoma (a collection of blood under the skin or in the deeper tissues)
  • Weakness of the muscles of the face, head and neck, which can have undesirable effects on swallowing, vocal cord function and eye movements (double vision)
  • inflammatory reactions – especially associated with unregistered dermal filler products which may require surgery to remove.
Frequently Asked Questions

We regularly get asked about our procedures, so we have put together a couple of questions we get asked on a regular basis. If there is something else you would like to know, please get in touch!

No, our team is selective in who they treat. Below is a guide of patients who may not be suitable for treatment

  • Anyone under the age of 18
  • Active skin disease, inflammation or skin related problems. 
  • Pregnant, breast-feeding or women trying to conceive a child
  • Individuals with medical conditions that lower the body’s immune response or individuals undergoing therapy that is immunosuppressive may be more prone to infection by a skin injection procedure
  • Patients on Accutane 

Due to Australian regulations, we cannot name medicine online. We only stock premium TGA approved brands of dermal fillers.

Cheek fillers last anywhere from 12-18 months. The body will break down the product over a number of months. Every patient’s body will do this at a different rate, hence the varied longevity.

At One Cosmetic we like to start small with all fillers and build. Aesthetic treatments are not a race and can be performed in multiple sessions. Your practitioner will guide you through the amount needed to achieve your goals.

When our Cosmetic Injectors show you example photos of jawline filler before and after, you will see the increased definition between the face and neck for a strengthened and defined jawline. By adding volume to specific areas, jawline fillers create a more defined and angular jawline, contributing to a more balanced facial structure.

Jawline fillers for men and women are tailored to each individual’s facial structure and aesthetic goals. While you must be above 18 years of age to receive jawline filler, our clinicians will take the time to get to know you and provide honest advice on the best course of action.
