Jawline Slimming Sydney

One of the most popular treatments at our Sydney clinic is jawline slimming injections. It is such a great way to make a square jaw or square face look more oval. With these injections, the patient’s face goes from a more masculine square shape to a gently curved and feminine upside down egg shape or a heart shape.

How long does it take to kick in?

The masseter treatment with muscle relaxing injections takes up to 8 weeks to reach its full effect. Your review appointment after the treatment will be at 6-8 weeks. At this appointment, the results will be assessed

Is masseter treatment only suitable  for the Asian face?
Although very popular with Asian patients, the masseter slimming injection treatment is suitable for anyone who would like to slim down the lower third of their face ie those who think their faces are too round or too square. It is also good for patients who have bruxism, which is a problem with excessive jaw clenching. It is really good for feminising the face and making it appear more soft and pretty.

Who is it good for?

It is good for patients with Bruxism, ie excessive grinding of the teeth or clenching of the jaw. Treatment of bruxism may improve the symptoms, which include hypersensitivity of the teeth, headaches, aching jaw muscles. Treatment with muscle relaxing injections will also improve the appearance of the hypertrophied or enlarged jaw muscles, which can make a face look too square.

What happens during treatment?

The patient is told to chew, so the doctor can feel the outline of the masseter muscle. Ice is applied, then the doctor makes several injections into each masseter muscle on the face. The review appointment is then made for 8 weeks later to assess results

Any complications or side effects?

Side effects for masseter treatment are very uncommon, but can include bruising and headache. Other complications may include patient requiring further treatment for uneven or asymmetrical masseters or problems with smiling. These complications are very rare with good injection technique.

Does it hurt?

Masseter injections for jawline slimming is probably the least painful treatment we perform at our clinic. We offer many options for pain relief eg ice, topical numbing cream, happy gas (nitrous oxide) and penthrox. However, with masseter treatment, all patients just choose to have ice because it is so easy and quick and involves minimal discomfort

Will I bruise?

Although uncommon, bruising is a possibility with masseter injections. Most patients are happy to go straight back to work after treatment

Is there any downtime?


Is it suitable for any ages?

It is suitable for adults. With those in older age groups when the skin is slower to retract, smaller doses may be used and then more added every 8 weeks so that there is no worsening of jowls

Do I have to continue with treatments?

You don’t have to continue with treatments, but most patients will love the results and will want to continue the treatments.  If you do not continue with treatments, it is likely that over time the masseters will grow again and the squarer jawline will reappear

What product is used?

Our preference is to use the UK brand of antiwrinkle injections. We cannot name them on our website due to Australian TGA regulations.

How long does it last?

After the first treatment, the patient attends for a review appointment in 8 weeks. If at the review appointment, the desired results haven’t been achieved, more injections are recommended on this day. If the desired results have been achieved at this appointment, then the patient should be seen every 3-4 months for 2 years. After this, the patient goes onto a maintenance dose, which for some patients is a significantly lower dose.

What is the Cost?

Cost varies depending on the size of the patient’s masseters, their age and what level of results they would like to achieve.

Minimum cost is $390

Typical cost is $730-$830

Maximum cost is $1150

With maintenance treatments (ie after patient has been having regular treatments for 2 years), the aim is to reduce the amount of product used if possible. Typical maintenance dose is $380-$520

What is the schedule for maintenance?

After results have been achieved, treatment every 3-4 months at the inital dose. After 2 years of treatments, dose is slowly reduced to see if a lower maintenance dose can be used. Often a smaller dose will be required every 4 months
