About the treatment

How do double chin injections work?

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.

Double chin injections vials contain an acid which is found naturally in the body. This acid is similiar to the one released by the gallbladder that helps dissolve fatty foods when you eat them.


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.

How many vials am I likely to need for treatment?

Most female patients need 2 vials per treatment and need at least 2 treatments to notice results.

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.

What are the risks 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.

Who is best suited for double chin injections?

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.

With this in mind the majority of the patients that we treat at Cityskin have a mild fullness under the chin (1 on the scale below).

Results

How many double chin treatments am I likely to need?

We recommend at least 2 treatments in order to see results. Some patients need up to 4 treatments to see full results. The number of treatments that you need depends largely on the amount of fullness that you have under the chin. These treatments are usually placed around 8 weeks apart.

What sort of result can I expect?

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.

How long long does the treatment take?

The actual injections for double chin treatment only takes about 5-10 minutes. At Cityskin, we use anesthetic to numb the area first, as this particular treatment without any anesthetic should quite uncomfortable. Depending on the size of the area will depend how many injections you will receive. The injections for double chin are spread out in a 1cm grid to cover the marked area within the ‘safe zone’. Each one of these injections only take a few seconds, much like anti-wrinkle injections.

Prior to the procedure, you will have had a thorough consultation with our medical practitioners, filled out all necessary paperwork and consent, and a ‘before’ photo will be taken for your personal record. You will then be marked out with a special stencil, and numbed

Are double chin injections painful?

At Cityskin 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.

How much does it swell after double chin injections?

The video below shows the swelling that occurred 20 minutes after double chin injections at Cityskin. The patient received 2 vials of product and 3ml of local anaesthetic. The amount of swelling that occurs can vary but this is a good representation of how much swelling you will see with 2 vials.
