Double Chin Injections in Melbourne | from $600 at Cityskin

Double chin injections are an effective, non surgical way to reduce fullness under the chin. Cityskin in Melbourne was one of the first clinics in Australia to perform double chin injections and we have treated hundreds of patients since the product was launched in 2017. Cityskin has clinics across Melbourne and consultations are free of charge. Book a free consultation to see whether you are a good candidate for double chin injections.

How do double chin injections work?

Double chin injections work by 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.

At Cityskin in Melbourne we use the American The product used to dissolve the double chin 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.

Am I suitable 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).

Who is not suitable for double chin injections?

Patients are not suitable for double chin injections if there is significantly loose skin under the chin or if there is an active infection under the chin.

The only contraindication on the product information sheet is ‘active infection‘ in the treatment area. At Cityskin we would include active acne under the chin as a contraindication.

How many vials am I likely to need to treat my double chin?

Most female patients need 2 vials per treatment and need at least 2 treatments to notice results. Have a quick look at our video below as a guide to how many vials you may need for treatment. If the area that you would like to treat is the size of a credit card or larger you may want to consider an alternative to double chin injections – ideally liposuction – as using 3 or more vials per treatment may start to become uneconomical. We don’t offer liposuction at Cityskin unfortunately but we’re just trying to be honest and upfront to give you the best possible outcome.

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.

How many double chin treatments are you likely to need?

This is the most difficult question to answer but it varies greatly between patients. 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. In some cases patients are happy with their results after just one treatment but these patients are generally those with a very small area of fullness under the chin.

What results can you expect from double chin injections

Studies show that with a full course of treatments 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 fullness1.

What to expect on the day of treatment

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

The actual injections for double chin treatment only takes about 5-10 minutes. At Cityskin in Melbourne we can 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.

Dr Brown from Cityskin in Melbourne has made a double chin treatment guide for practitioners. In this video Dr Brown explains how to use local anaesthetic to make the injections almost pain free.

At Cityskin we have spent the past 4 years perfecting our treatment to make it as pain free as possible. The double chin treatment below took under 5 minutes to perform and the patient described a pain level of ‘1/10’ during the injections.


How much does it swell after double chin injections?

All patients experience swelling immedialtely after double chin inejctions. The swelling is directly related to the amount of vials used on the day – more vials tends to cause more swelling

The video below shows the swelling that occurred 20 minutes after double chin injections at Cityskin in Melbourne. 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.

How long does swelling last after double chin injections?

Swelling after double chin injections peaks on the day of treatment and is most noticeable for the first 5 days. Once the initial swelling has settled it can feel firm under the chin for a few weeks – this is the inflammatory effect of the treatment and this helps tighten the under chin area.

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:

1. 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.

2. 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.

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

4. 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.

After 4 years of treating hundreds of patients at Cityskin we have not affected the smile muscle in any of our patients.

What differences are there for men having double chin injections?

Men tend to have a larger treatment area so men may need 3 or 4 vials per treatment compared to an average of 2 vials per treatment for women. If men use more vials per treatment you are likely to see slightly more swelling after the treatment.

We always counsel men that double chin injections can in rare cases cause temporary patchy hair loss under the chin in the area treated. This generally lasts for up to 3 months before growing back.

Men need to attend the treatment appointment clean shaven. This allows us to apply to temporary grid under the chin and reduces the risk of infection from treatment.

Are double chin injections safe in pregnancy or when breastfeeding?

Double chin injections are not safe when pregnant or breastfeeding

Are double chin injections painful?

At Cityskin we can 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.

When should I have double chin treatment before a major social event?

We recommend having double chin injections at least 6 weeks before a major social event (wedding, graduation) to allow for any swelling or firmness under the chin to completely settle and resolve. It often resolves far earlier but it is best to be cautious.
