Permanent double chin fat removal / treatment – how does it work?

The double chin injections contain a product which contains deoxycholic acid, found naturally in the body, and helps absorb fat in food. The product is injected into the fat in the double chin area and permanently destroys the fat cells by a process known as adipocytolysis. Once the fat cells have been destroyed they cannot store fat again. Imagine your fat cells are balloons and double chin injections are darts. Injecting the product under the chin is like throwing a dart at fat cells. Once they have been popped they cannot be blown up again.

10 key things you need to know about permanent double chin treatment at Cityskin in Melbourne

We will cover each of these points in more detail below, but the burning questions that you need answering are:

  1. What is the name of the product? – The product has different names in the USA and Australia but it is essentially the same product. Frustratingly, we are not allowed to mention the name of the product on the website due to Australian law. We have to call it ‘double chin injections’ instead of using the actual brand name.
  2. Are double chin injections painful? – We are now using local anaesthetic to numb the double chin area before treatment. This means that, after injecting local anaesthetic, you will barely feel the double chin injections. After injection the area can feel firm and a little tender but patients often use panadol and ice to reduce this discomfort.
  3. Are double chin injections safe? – Yes. It is a non surgical treatment with an acceptable side effect profile.
  4. Does the product permanently remove double chin fat? Yes – double chin injections permanently destroys double chin fat. Once the fat cells have been destroyed they will never return.
  5. Am I guaranteed to see results? – 68.2% of patients noticed at least a 1 grade or more improvement in the fullness of their double chin area (see scale below) and 16% of patients noticed a 2 grade or more improvement in double chin fullness.
  6. How many vials do I need to treat my double chin? – The average patient needs at least 2 vials injected into the double chin fat at each treatment.
  7. How many treatments will I need? – We recommend at least 2 treatments of at least 2 vials to see results.
  8. How much do double chin  injections cost? – At Cityskin clinics in Armadale, Hampton, Sorrento in Melbourne the cost is $550 per vial. Mr Koppert at Cityskin Kew charges $625 per vial. It is likely that you will need at least 4 vials in total to complete a full treatment.
  9. Will I see results straight away? – No, it takes up to 6 weeks for you to notice the effects. We treat patients at 6 week intervals.
  10. What are the main side effects of double chin injections? – We expect swelling around the treatment area on the day. We like swelling because it means the treatment is working. In fact, we say please call us if it does not swell! Swelling means that the body is destroying fat cells. This also means we recommend icing the skin and resting at home after treatment rather than going back to work.

Lessons learn from 6 months of treating patients with double chin injections


How many vials am I likely to need for my treatment?

This is one of the most common questions that we are asked by patients enquiring about double chin injections.

How many double chin vials do I need?

The photo above shows the how large an area 1 vial, 2 vials and 3 vials can treat. You can do the ‘pinch test’ in-front of the mirror to estimate how many vials you might need. The fullness under the chin that we can treat is where you can pinch a little finger’s width of fat between your finger.

1 vial of double chin injections will approximately treat the area of a 50 cent coin. A small number of patients fall into this category.

2 vials of double chin injections is approximately the same area as a packet of chewing gum. Most patients fall into this category.

3 vials of double chin injections is approximately the same width as a Myki or credit card.


A video explaining how many vials of double chin treatment you may need

At Cityskin we have made a video guide to help you estimate how many vials you may need. Use this as an estimate before your appointment.

A guide to permanent double chin treatment by Dr Jonathan Brown at Cityskin


Which patients are best suited for treatment?

The treatment guide below shows a grading scale for double chin fat, also known as ‘sub-mental fat’. It ranges from 0 (no localised sub-mental fat) to 4 (extreme submental convexity). The ideal patient for would be someone who is a ‘2’ or ‘3’ on sub-mental scale, so someone with moderate to severe sub-mental fullness.

double chin treatment guide


Who is not suitable for double chin injections?

  • If you have no sub-mental fat (‘0′ on the scale above’) then double chin injections is not suitable for you.
  • If you have a lot of loose skin under the chin then double chin injections may not be effective.
  • If you have an active infection of the skin under the chin then you cannot have treatment.


How are double chin treatment performed? What happens on the day? Watch Dr Brown treating a patient in the video below

In this video, Dr Brown performs a double chin treatment at Cityskin.

To treat submental fat with we place a non permanent template on the skin (see photo above) and apply water. This leaves small dots on the skin as a guide for where to inject. We then ice the area to reduce any pain and clean the skin with chlorhexidine before placing small injections into the submental (under chin) fat. The treatment requires approximately 20 small injections into the dots provided above.

What are the side effects of double chin injections?

The vast majority of side effects from double chin injection treatment are mild and not permanent. Studies show that with each treatment side effects occur less frequently and to a lesser degree.

The most common side effect we see after treatment are as follows:

Swelling around the area injected – We expect to see swelling. It means the treatment is working! In fact, we say please call us if it does not swell. We recommend not going back to work on the day of treatment and using ice on the neck intermittently in the hours after treatment.

Temporary numbness under the chin. Approximately 50% of patients will feel this slight numbness after treatment, with symptoms wearing off after 30 days on average.

Warmth and redness – 40% of patients will feel warmth or redness under the chin on the day of treatment.

Firmess under the chin – Studies show that 16% of patients will feel firmness or ‘induration’ under the skin after treatment. This is not a worrying symptom and resolves, on average, after 51 days according to studies.


Rarer side effects such as temporary problems with weak smile and facial muscles and trouble swallowing (2%) have been reported.

The risk of affecting the smile is due to the small chance of temporarily affecting the marginal branch of the facial nerve. The anatomy of the nerves in the face differs from person to person and in 2% of treatments a small branch of the facial nerve can be affected. This would present as a temporary problem with the smile muscle (see image below). The affected side would be more difficult to perform a full smile. The problem is temporary and the average time to resolve is 44 days.

Are double chin injections painful?

A number of small injections using tiny needles are made into the double chin area. We use local anaesthetic to numb the double chin area before injection. This means that when we treat the area with the double chin injections you can barely feel it. After an hour or so, when the local anaesthetic wears off, it can feel fuller under the chin and you may feel a slight ache. We recommend using panadol and icing the area to reduce the discomfort. Remember not to leave the ice on the skin for more than 10 seconds at a time to reduce the risk of a cold burn.
