Fat Dissolving Injections

The Basics

Fat Dissolving Injections are the latest non-surgical treatment to hit Australian shores. Fat dissolving treatments at Cosmos Clinic can be used to effectively reduce the appearance of chin fat that causes a stubborn double chin. Fat dissolving injections destroy the membrane of the fat cells to minimize the appearance of fat in the double chin area.

The Procedure

Tiny, precise injections are administered into the submental area. Numbing cream (local anesthetic), and ice packs and small needles are used to minimize discomfort. Procedure takes up to 30 minutes.

Suitable for men and women over 18 years of age

The Results

Fat reduction is visible 6 weeks after your 2nd treatment. Fat dissolving injections cause fat cell breakdown, meaning the can no longer store or accumulate fat 1

Top Fat Dissolving Injections Questions

What is Submental fullness?

Submental fullness refers to the excess fat  under your chin area. Submental fullness can be caused by:

  • Ageing
  • Genetics
  • Weight Changes

Patients with Submental Fullness (a double chin) may feel like they look older and heavier than they actually are. In a recent survey, 60% of Australian women said they are concerned about a double chin.

What are fat dissolving injections for Submental Fullness?

Cosmos uses the latest fat-busting injectable drug.  Developed by the pharmaceutical company Allergan, the treatment provides:

  • Clinically Proven: Reduces the appearance of submental fullness (double chin fat)
  • Customised Results: Injectable treatment tailored to suit each patient’s needs and circumstances
  • Contoured Profile: More than 75% of patients reported satisfaction with the appearance of their face and chin. Feeling happier and younger, less embarrassed and less self-conscious (*Results may vary from patient to patient)

The treatment is a synthetic form of deoxycholic acid; which is a naturally occurring molecule produced in the body to aid in the absorption of fat. When it is injected into the tissue below the chin, it disrupts the fat cell membrane.  As a result, the cells breakdown and release their fatty contents. The body then naturally metabolises and excretes this fat. This breakthrough non-invasive double chin treatment provides another option to the growing number of patients wanting to address this stubborn area. These double chin injections provide patients with treatment options beyond invasive procedures.

The Procedure. What does it involve?

Like dermal fillers, Fat Dissolving Injection procedures take approximately 20-30 minutes and patients have up to 50 small injections during one treatment session. A template is applied to the target area to ensure even distribution, whilst avoiding anatomical landmarks A series of small injections are administered.  When injected correctly, all the healthy cells around the submental fat, remain intact and unaffected, as well as nearby nerves and muscles. With proper care and precision, the chin and neck area can be effectively treated – resulting in a slimmer chin profile.

Who is suitable for Fat Dissolving injections?

Fat Dissolving Injections are suitable for both men and women over the age of 18. Ideal candidates will have to have excess fat under their chin, which could either be from weight gain or genetics. It is another non surgical option for those who want to reduce their double chin but are not suitable candidates for Cool Sculpting treatments (Cool Sculpting applicators are a fixed size which may not fit everyone) or for those who do not want to undergo surgical procedures such as liposuction, full facelift or other invasive surgery.

Will I experience any pain?

Most patients experience mild to moderate pain to the area being treated.  However, to reduce discomfort, the cosmetic injector will numb the area pre-treatment.

What can I expect after the procedure?

Please note that the most common side effects are swelling, bruising, pain, numbness, redness and areas of hardness around the treatment area. All of which will have to be resolved before subsequent treatments.

  • Swelling occurs immediately after your treatment making your skin feel tight. The swelling reduces slowly over a 2-3 week period.
  • Bruising may occur with all treatments involving injections and your clinician will try to minimise this as much as possible
  • During the treatment, there is some discomfort and your clinician will try to reduce this by applying numbing cream and cool packs. After your treatment, the area may feel sore to touch but this will reduce within a few days
  • Numbness and the formation of small hard areas are also a common side effect which improves day-by-day

How many treatments will I need?

The number of treatments required to achieve good results will depends on how much submental fullness the patient has. But many patients have experienced visible improvements within 2 to 4 treatments. Patients can have up to 6 treatments of fat dissolving injections administered to achieve the best result. (*Results may vary from patient to patient). Consecutive treatments can be done every 4-6 weeks, and this will ensure superior results. Results are long-term and long-lasting, and most patients will not undergo further treatment for at least 4 years

Results. What and when can I expect them?

In most cases, visible results are seen at around 4-6 weeks after your second treatment (*Results may vary from patient to patient), and with each subsequent treatment further improvement is seen. You will be encouraged to book a review appointment so your clinician can take photos and monitor your progress.
