Fat Dissolving Injections

Double Chin Reducing Injections (Belkyra®)

"I am delighted to be one of first doctors in New Zealand to offer this treatment. It has undergone extensive clinical trials and is a safe and effective non-surgical approach to the very common problem of sub-mental fat, or double chin" - Dr Philip Frost

Belkyra® is a prescription only medicine which when injected below the chin, breaks down fat, resulting in a more contoured neck profile and jawline. Sometimes, no matter how much you diet or exercise, the fullness in this area will not go away.

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 accumulate and 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.



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.


The Treatment

Belkyra® is injected into the fat under your chin, with small amounts administered at several points. The number of injections you need will vary according to the amount of excess fat you have. Dr Frost will tailor the doses according to your individual need. Local anaesthetic and cooling packs are used to numb the area before treatment.

Most clients need at least two treatments and some will need up to a maximum of six treatments spaced four to eight weeks apart. You can expect swelling in the area, sometimes significant swelling, for up to 14 days. You may also experience tenderness and bruising, warmth and tingling, small areas of hardness, and itching around the treatment area.
