Double chin reducing injections (Belkyra®)

Belkyra® is an FDA-approved injectable treatment that destroys fat cells in the area under the chin to improve your profile. Belkyra® contains a synthetic version of deoxycholic acid which imitates naturally occurring deoxycholic acid.  When injected under the chin, it works by bursting the fat cells like a balloon. The fat released by the fat cells is then removed by the body’s repair system and transferred by the blood stream into the liver where it gets excreted out of the body.  Belkyra® is a prescription only medicine, so treatment is only available from our Skin Institute cosmetic doctors. They will customise the treatment to your individual anatomy and circumstances.

‘I have realised many of my patients are concerned about their double chin and it is wonderful to finally be able to offer a well-researched non-surgical treatment that really works”

How does Belkyra® work?

Belkyra® is injected into the fat under your chin by a series of injections. The body’s own healing systems clear the debris away. It induces an inflammatory reaction so each patient responds differently. Some patients may need 2 treatments and some 4 to 6 to obtain desired result. Treatments last 30 to 40 minutes and are best spaced 6 to 8 weeks apart.

Although Belkyra® doesn’t restrict your activities, you will be swollen after treatment, so you may not wish to go straight back to work. Your double chin will get approximately twice as big for a least a couple of days, and remain swollen for up to 14 days. This swelling is actually crucial to your result. It is a sign of successful treatment and helps the healing process in the area.

Belkyra® treatment does not need to be repeated like Botox or fillers. Once you have completed your course of treatment, it is not expected that you should need to repeat the treatment.  Belkyra® has been scientifically proven to be effective and long lasting with an excellent safety profile.

How much will treatments cost?

For a moderate double chin, minimum of two treatments are required at a cost of $2,700. Further treatments are approximately $1,500 per treatment. Some people require up to six treatments.

A large double chin may be more expensive than this, however, a consultation with a doctor will give you a more accurate price. Click to book a consultation.

Are there any side effects?

The most common side effects associated with double-chin reducing injections include: pain at the injection site, swelling, bruising, numbness, redness, tingling, formation of small areas of hardness, warmth and discolouration, and itching around the treatment area.

Our Skin Institute doctors will fully discuss Belkyra® with you at your consultation and can answer any questions you have.

Does it really work?

Yes. It works. Research shows Belkyra® effectively removes the superficial fat lying on top of the platysma muscle in the neck.

More than 75% of patients treated reported positive results*. Most people treated have experienced a visible improvement in their chin profile after two treatments, although four may be necessary for maximal improvement*.

Your Skin Institute doctor will examine your neck and advise if Belkyra® is appropriate for your concerns.  Sometimes, the appearance of a double chin can be caused by other factors, like fat under the muscle, an enlarged muscle under the jaw (digastric muscle), or loose skin. In this situation, even though the superficial fat has been removed, the area may still retain some fullness.

Who is suitable for treatment?
  • You’re aged 18 and over
  • You have unwanted fullness around the chin and neck area.
  • You have minimal to no excess skin around the neck and chin area. This treatment designed to target the stubborn fat cells, not skin laxity.
  • You’re bothered (unhappy, self-conscious, embarrassed) by fat under your chin.
  • You feel the condition makes you look older or heavier than you actually are.
  • You don’t want to have surgery
  • You eat well and exercise, but submental fullness does not go away

Please note that this treatment is not suitable for pregnant or breastfeeding women.

What can I expect during treatment?

Prior to administering Belkyra® your doctor will apply ice packs and/or injectable local anaesthesia to the treatment area to make you more comfortable. They may also suggest that you take paracetamol before your appointment.
