Double Chin

A number of different treatments are available to sculpt, contour & define small amounts of stubborn fat on the jawline/chin and other areas.

Solutions for excess chin/neck volume

Do you dislike your jawline or feel you have a double chin? You are not alone – a 2015 survey of American men and women revealed that 67% were bothered by the fat beneath their chin, the same number that were concerned about forehead and frown lines.

Here in Australia, 59% of women (in 2016) said they are concerned about a double chin – that’s more than those concerned about forehead and frown lines (52%). The shape and contour of the chin and neck play a fundamental role in our appearance, and fat accumulation in this area can hide our underlying definition.

At SkinBox, we have a variety of treatments that we can use to address the chin/jawline area. We are also able to recommend other options that are not available in-house if these are more suitable to your needs. Treatment options include medical, surgical and energy-based devices, and it may be necessary to use a combination approach to achieve your goals. The first step in an in-person consultation with one of our Cosmetic Doctors to assess the anatomy of your chin/jawline and explore which option(s) would be most suitable for your needs.

We have extensive experience with the medical treatment of excess chin fat, being one of the key sites in a Phase IV clinical study of this treatment. Our principal doctor is on the Faculty of the Allergan Medical Institute, training other practitioners in this treatment, and has spoken at conferences about its use.

FAQs about medical treatment of a double chin

What causes a double chin?

A double chin, known medically as “submental fullness” can be caused by:

  • Ageing – It can develop naturally as we age
  • Genetics – It can be part of our DNA
  • Weight changes – It can appear as a result of weight change (diet and exercise may not be enough to remove the fullness).
Who is potentially suitable for non-surgical treatment of excess chin fat?

The following information is for educational purposes only and should not be taken as medical advice:

The best results are seen in patients with a BMI within the normal range, who have a localised fat deposit beneath their chin. Often these patients feel that they do not have a defined jawline, or that their face appears to blend into their neck. This treatment may be for you if:

  • You’re bothered (unhappy, self-conscious, embarrassed) by fat under the chin;
  • You feel the condition makes you look older or heavier than you actually are
  • You are someone who grows a beard or wears a scarf to hide your jawline, or avoids having photographs taken that show your side profile;
  • You don’t want to have surgery;
  • You eat well and exercise, but your double chin does not go away.

A medical consultation is required to assess your suitability and explore all available treatment options.

How do non-surgical & medical treatments of excess fat actually work?

The following information is for educational purposes only and should not be taken as medical advice:

The active ingredient that is used for the medical treatment of localised excess fat deposits is a synthetic, non-animal form of a bile acid substance found naturally in the body. In your body, bile acids are produced in the liver and secreted into the gut to aid in the breakdown and absorption of fat cells in the diet. When the synthetic version is injected into a localised area of excess fat, it causes disruption of the biological membrane around the fat cells in that region, triggering destruction of those cells in a process called adipocytolysis. Once destroyed, these cells are gradually but permanently eliminated by the body’s natural metabolism and the contour of the area is improved.

With the non-surgical energy-based devices, the fat layer beneath the skin is heated to a temperature that causes adipocytolysis. We have two different machines that can be used depending upon the shape & size of the treatment area and your medical suitability for each device.

What areas of localised fat can be treated medically?

The following information is for educational purposes only and should not be taken as medical advice:

It is possible to treat small localised areas of fat under the chin, jawline and jowls, as well as the pocket of fat in front of the armpit (known as bra-fat). Larger areas are more suitable for alternative treatments, either with energy-based devices or surgical intervention.

Will the treatment hurt?

All of the treatments we use at SkinBox for the reduction of fat beneath the chin are entirely tolerable. Some patients can experience mild discomfort at the time of treatment.

What are the side effects of medical treatment for localised fat-reduction?

The following information is for educational purposes only and should not be taken as medical advice:

In general, fat-dissolving treatments are well tolerated, but as with any medical procedure, some side effects can be expected.

Commonly, patients will experience some mild redness and/or light bruising at the treatment area, and some mild pain or tenderness for up to a week after each treatment.

You should expect some moderate swelling of the treatment area, which is likely to be quite obvious in the first 48hours and usually resolves over the first week. The treatment disrupts the fat cell membrane, which causes an inflammatory process and swelling as the body eliminates the contents of the fat cells. This natural tissue-injury repair process can lead to additional tightening and retraction of the overlying skin, and so is considered part of the treatment process rather than an unwanted adverse effect.
Occasionally, patients may experience temporary numbness in the treated area that resolves spontaneously over the following weeks/months, or small, firm tender lumps/nodules below the skin. These bumps will also resolve on their own over several weeks to months.

It is important that this treatment is performed by a qualified and trained healthcare practitioner with specific knowledge of the relevant anatomy of the treatment area. This minimises the possibility of temporary damage to nerves and blood vessels in and around the area. At SkinBox, all our injectable treatments are carried out by doctors.

How many treatments are needed?

The following information is for educational purposes only and should not be taken as medical advice:

The number of treatments given varies depending upon the amount of fat in the area. The average patient requires between 1 to 4 treatments but up to 6 treatments can be given. Treatments are spaced at least 6 weeks apart to give the body time to eliminate the treated fat cells between treatments. During your initial consultation, we can usually give you an accurate estimation of the expected number of treatments you will need. If it is likely to be more than 4 treatments, other treatment options are likely to be a more cost-effective solution.

How much does medical treatment for localised fat-reduction cost?

This depends upon your personal anatomy and an accurate quote can only be given in a consultation. Please see our Price List for up to date (general) pricing information.

When will I see results?

The following information is for educational purposes only and should not be taken as medical advice:

Medical treatment for localised fat-reduction is usually not a one-off event, it is a customised treatment journey. Since the body takes some time to metabolise the fat cells that have been destroyed in the adipocytolysis process, you may not see visible results until after the 2nd or 3rd treatment. Treatments are performed a minimum of 6 weeks apart, but these can be scheduled around work and social engagements that you may have, enabling you to remain in control of your treatment journey. Medicine is not an exact science and occasionally patients have quicker or slower results than we anticipate and if this is the case, your schedule can be adjusted as the journey progresses.

Are the results of treatments for localised fat-reduction permanent?

The following information is for educational purposes only and should not be taken as medical advice:


Results vary depending upon the individual anatomy, lifestyle, hormonal influences and the treatment modality used. No guarantees can be given.  However, if fat cells are physically removed or destroyed, rather than just made smaller in size, results tend to be long-lasting. If you gain additional weight after a fat-reduction procedure, the treated area will not gain as much fat back proportionally since the number of fat cells in that area have been permanently reduced.

What downtime should I expect?

The following information is for educational purposes only and should not be taken as medical advice:

Downtime will depend upon the treatment modality (medical/surgical/energy-based).

Some treatments lead to expected swelling, as this is part of the inflammatory response that leads to the natural repair process and tightening of the overlying skin.

Many patients like to time their treatment for the autumn/winter months so that they can comfortably wear a scarf if necessary.

Downtime specific to your treatment would be discussed at your consultation.
