About facial slimming

How do facial slimming injections work?

The masseter muscle, shown in the image below, is the main muscle of biting and grinding. It is a strong muscle in comparison to the frown muscles or forehead. Anti-wrinkle injections placed into the masseter muscle reduce the strength of the muscle and reduce its’ size leading to a slimming effect.

Melbourne tooth grinding and bruxism treatment

We usually perform 3 to 5 small injections of anti-wrinkle injections into the masseter muscle, as shown below. The way I like to explain the mechanism of action is similar to that of putting your arm or leg into a plaster cast after a break. Preventing the muscle from contracting over a period of time weakens the muscle and reduces its size.

Facial slimming treatment lasts longer than in other areas of the face such as the forehead or frown. It lasts longer because we are able to safely use larger units without the risk of over-treating. Click on the video below to watch Dr Greg Scher from Cityskin discussing how long facial slimming lasts.

How long do facial slimming treatments last?

Facial slimming results last up to 6 months provided the correct amount of units are used. When you can feel the bite muscle contracting well again we recommend coming back to have a repeat treatment.

How long does it take for facial slimming to work?

Facial slimming injections take up to 4 weeks to work as it takes time for the muscle to relax and reduce in size. The maximal effect will be about 8 weeks after the treatment.

How many units do I need to treat slim my jawline?

We generally recommend between 20 and 35 units each side to slim the jawline. Men generally need more units than women as they have stronger muscles. We will assess the muscle on the day and recommend how many units you will need.

How are facial slimming injections performed?

The image below shows Dr Brown marking a patient’s skin before treatment. The yellow dots are the injection points for the masseter muscle. We are always mindful of patient anatomy – in particular avoiding the muscle known as risorius.

Risks of facial slimming treatment | How we reduce your risk

What are the risks of facial slimming treatment?

  • A small bruise after treatment: This is unlikely, however, as the jaw area is not particularly vascular.
  • Difficulty grinding tough foods: The masseter muscle will weaken as a result of the injections and you may notice it being more difficult to grind food. This is not a permanent side effect.
  • Affecting the smile muscle: The masseter muscle lives very close to a muscle called ‘risorius’, as shown by the red muscle in the picture below. Risorius is the muscle responsible for opening the mouth wide when smiling. We are very careful to avoid this muscle when injecting the masseters to avoid the smile from being affected. In the unlikely event of the smile muscle being affected it would wear off quickly with no permanent problems.

The Cityskin facial slimming technique

Cityskin practitioners use a technique using a small number of injections within the lower part of the bite muscle to reduce the risk of side effect. Watch the video below to see Dr Brown explaining this technique.

How to safely treat the masseter muscle to avoid affecting your smile

So , I thought I’d do a quick tutorial on how to safely inject the masseter muscle. Now, the masseter is the bite muscle, the main bite muscle. Of course I’ve got temporalis, which contributes towards biting as well, but when we treat tooth grinding and facial slimming, that’s the muscle that we inject and we do four or five little injections into that muscle to treat it. Now, the muscle that we need to avoid is one called risorius and that’s the one that pulls the muscle out and it pulls the smile out to the side. So when I’m smiling like this, that’s pulling on risorius. When we treat the masseter, we mark a line between the tragus of the ear, the corner of the ear here and the corner of the mouth. And we treat a centimeter below there and we save quite far back. So that means you can get great results, but avoid hitting the smile muscle. We perform hundreds of treatments here at City Skin every year so you can be assured that you’re in safe hands when you come and treat with us.

Facial / jawline slimming FAQs

Treating the jawline with anti-wrinkle injections can create a strong jawline and angle of jaw. The patient in this photo has had anti-wrinkle injections over a 2 year period to treat tooth grinding.

The the photo shows a beautiful defined jawline which is a result of the flattening of the masseter muscle. We often use anti-wrinkle injections in conjunction with dermal fillers to sculpt the jawline.

We commonly see this result after long term facial slimming / tooth grinding treatment with anti-wrinkle injections. The video below shows Dr Brown from Cityskin discussing this case in more detail.

Jawline contouring can be achieved using anti-wrinkle injections into the bite muscle. We often see, in patients under 40, a more angular and contoured effect to the jawline which is more evident in 3D rather than just in photos. The photo below shows a patient who had treatment to her masseter muscle with the effect still visible after 9 months

Buccal hollow – contouring effect after anti-wrinkle injections

The injections are the least painful injections of all the treatments that we perform at the clinic. It feels like a small sting when you have an injection.

This is an account of a patient having treatment with us at Cityskin and writing about her experience:

“I have hypertrophied or enlarged jaw (masseter) muscles most likely due to teeth grinding or clenching at night time and these were easily felt when clenching my teeth but also quite visible by my square or ‘chubby’ jawline. Having treated quite a few patients for this I decided that I would try the treatment myself not only to see what results were possible but to allow me to understand what happens for the patient.

The procedure itself took less than 10 minutes and simply required me to clench my teeth whilst 4-5 small injections were made into the masseter muscle on each side of my lower jaw. Ice was used for comfort and the pain was minimal and I was able to return to work without any obvious signs of treatment.

Over the next 3-4 weeks I noticed a narrowing of my jawline and a visibly slimmer appearance to my face. But more importantly, I have also found I have far less headaches and a less ‘tired’ jaw. Interestingly, at about the 2 week mark I did notice a small amount of difficulty in biting/chewing food but this seemed to resolve itself as quickly as it occurred and I now have no problems.

With repeated treatment every 4-6 months I should notice the muscle start to atrophy (shrink) further with ongoing treatment becoming less frequent”.

Cityskin Patient

This is an urban myth which is not true. The anti-wrinkle product that we use is broken down naturally over a period of months and then muscle strength returns again. The muscle will be weaker than it was before having treatment but, with time, it will return to full strength again.

Cityskin medical professionals are experts in facial slimming and perform hundreds of treatments per year so you can be confident that you are being treated by an experienced injector.

No – a unit is a measure of anti-wrinkle product. When we treat each masseter muscle we often use 4 or 5 tiny injections of 5 units of anti-wrinkle product. The amount of units in each injection depends on the total number of units that you are having injected.

Facial slimming treatment works best in patients who have strong bite muscles and a jawline which is not obscured by heavy lower cheeks. Treatment is on a case by case basis so feel free to book a consultation with one of our experienced medical practitioners for advice on whether jawline slimming will work for you.

Yes – there are other muscles that help bite and grind food. Place your fingers on the side of the head and clench your teeth – you will feel a muscle called temporalis which helps you to grind food. After jaw slimming treatment it may be more tiring to eat chewy foods.

We often say to patients that, before treatment when you clench your teeth, the bite muscle feels firm. Approximately 2-3 weeks after treatment the bite muscle will feel soft, a bit like a kitchen sponge. This is the point at which the muscle has been relaxed and you know that it is working.

Masseter injections and facial slimming injections are the same treatment. The masseter muscle is the muscle responsible primarily for chewing and is shown in the picture below.


We treat facial slimming and tooth grinding by injecting anti-wrinkle product into the masseter muscle. This causes the relaxation of the muscle and slims it down. Imagine going to the gym and doing weights for months then stopping gym for 6 months.

That is the way the treatment works – by reducing the ability of the masseter muscle to contract it reduces the size of the muscle and causes a slimming effect.

You do not have to wait until the muscle contraction completely goes back to its original state to have it treated again. As long as there is a small amount of muscle contraction, it can be treated.

Regular treatments can help give longevity to your results and regular treatments may mean you mightn’t need the same dose as the original, if the muscle has already been significantly weakened.

If you have had 10 units to each masseter that would mean 20 units in total. Use our helpful cost estimator below as a guide to your treatment cost using both the American or European anti-wrinkle brands.

Dermal filler can be used to give the chin more of a point and to give the face the ‘V’ shape that patients are often looking for. Using small amounts of dermal filler (usually approximately 1.0ml) we can expertly place the product to enhance the chin.

Chin dermal filler is a popular treatment in combination with facial slimming as it softens the jaw and elongates the chin.

Does dermal filler treatment to the chin hurt?

It is one of the least painful areas to treat with dermal filler so patients tolerate the procedure very well. We often use numbing gel before your treatment to numb the area before injecting to further reduce discomfort

How much does chin dermal filler cost?
