Cosmetic Treatment
Jawline enhancement brings strength and character to the jaw, where this may appear naturally weak.
During a jaw enhancement treatment, dermal fillers fill out the area, effectively sculpting and reshaping the jaw. In some people, the concern is that the jawline appears weak or that it may be unbalanced. We can use dermal filler injections to enhance and even out the facial structure for improved facial alignment. In the instance where jowls are of concern, dermal fillers are appropriate to help restore collagen (a protein in the skin that is responsible for youthful volume) and elastin (which maintains the skin’s ability to bounce back), resulting in the jawline area appearing both tighter and lifted.
Whenever you have any cosmetic treatment, you want to choose an experienced and regulated clinic by the Therapeutic Goods Administration (TGA) to ensure you are getting a safe, tried and tested procedure.
Jawline filler works by imitating a naturally occurring substance within your body — a sugar molecule that exists naturally in almost all living organisms. Its normal function is to bind water, so it acts as a lubricant and shock absorber in movable parts of the body, such as joints. It is also essential for the transport of nutrients and in regulating water balance in the skin. By boosting your skin with this naturally occurring substance, jawline fillers instantly revitalise and add volume to the area, diminishing the appearance of lines and wrinkles and giving a natural, softer look. Our gel is very tissue-friendly and closely resembles that in the body.
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.
When you choose One Cosmetic, you will experience a customised jawline filler treatment plan that accommodates your needs. Jawline filler for men or women is an effective treatment to strengthen and contour a weakened jawline, create improved definition between the neck and face and correct jawline asymmetry that may be occurring.

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