Submental fat treatment in Kew, Melbourne

Fat Dissolving Injections Melbourne

Doctor-performed fat dissolving injections reduce a discrete pocket of fat where it is genuinely the cause of fullness, most often under the chin. The assessment comes first, because what looks like a double chin is frequently not fat at all.

What it is

What are fat dissolving injections?

Fat dissolving injections use deoxycholic acid, a substance the body produces naturally, to break down fat cells in a discrete, localised pocket. The most common use is a genuine submental fat pad, the fullness some patients carry under the chin at a normal body weight. Dr Rakib uses a cannula technique to place the treatment precisely in the fat compartment beneath the skin and above the muscle.

The treatment only helps when fat is genuinely the cause. Submental fullness is just as often driven by a recessed chin, loose skin or an undefined jaw-to-neck angle, and dissolving fat in those cases does not improve the area and can make loose skin look worse. This is why the assessment, not the injection, is what changes the outcome.

Under the chin is the most common area, but it is not the only one. Other small, discrete pockets respond to the same treatment: bra fat, love handles and small areas of the abdomen among them. The word that matters is small. This is a treatment for a defined pocket, not for general body fat or for weight loss, and whether an area is suitable is decided at consultation rather than online.

What it treats

What do fat dissolving injections treat?

Fat dissolving injections is most often planned for a genuine, discrete pocket of fat under the chin. The treatment only makes sense when it matches the cause of your concern; here is where it fits.

  • Double chin & lower-face fullness

    Explore this concern

    Why it happens

    A discrete pad of fat can sit below the platysma muscle between the chin and the neck. It is often genetic and not always related to body weight, and it is only one of several possible causes of submental fullness.

    Treatment role

    Where a discrete fat pad is confirmed as the cause, fat dissolving injections reduce it gradually over a planned course. Where the driver is chin projection or laxity, a different treatment is recommended instead.

Results

Each case is a single composite photographed at the practice: the concern that brought the patient in, the treatment performed, and the point at which the result was reviewed. Outcomes vary from person to person. This is clinical context, not a promise.

How it works

How do fat dissolving injections work?

Lower-face consultation at Aesthetic Doctors Australia in Melbourne Step 01

01 / 03

What deoxycholic acid does

Deoxycholic acid disrupts the membrane of fat cells in the treated pocket, so the cells break down and are cleared by the body over the following weeks. Because the effect is gradual and dose-related, the treatment is planned as a course rather than a single visit, with change building between sessions.

02 / 03

Why the cannula matters

Dr Rakib places the treatment with a cannula rather than a series of sharp needle passes, targeting the pre-platysmal fat compartment specifically. Precise placement in the correct plane is what keeps the treatment to the intended fat pocket and away from surrounding structures.

03 / 03

Why the diagnosis comes first

Submental fullness has at least four common causes: fat, a weak or recessed chin, skin laxity, and an undefined jaw-to-neck angle. Treating fat that is not there, or dissolving fat when loose skin is the real driver, wastes the treatment and can leave the area looking emptier and looser. The consultation names the dominant cause before anything is booked.

Whether it suits you

Are fat dissolving injections right for you?

The two lists below are where that answer starts; it is confirmed in person, never assumed. Balanced information protects you.

May be suitable for

  • A discrete, pinchable submental fat pad at a stable body weight
  • Patients wanting a non-surgical option for genuine, localised fat
  • Those comfortable with gradual change across a planned course
  • Realistic expectations of reduction, not a jawline transformation

May not be suitable for

  • Fullness driven by a recessed chin or an undefined jaw angle, where chin or jawline work is the answer
  • Loose or lax submental skin, where dissolving fat can worsen the look
  • A large fat pad better served by surgical reduction
  • Pregnancy, breastfeeding, or active infection in the area

The assessment

What happens at a fat dissolving injections consultation?

Expertise shows in process. Before any recommendation, your consultation examines:

Book your assessment
  1. 01

    Whether a discrete, pinchable fat pad is genuinely present

  2. 02

    Whether chin projection, skin laxity or jaw angle is the real driver instead

  3. 03

    Whether the pad is small enough for injections or large enough to refer for surgical reduction

  4. 04

    How many sessions the area is likely to need

  5. 05

    Standardised photography so gradual change can be judged objectively

What to expect

How long do fat dissolving injections take to work?

The short version: gradual reduction across a course, commonly around four sessions. Stage by stage:

  1. Day 0

    First session

    Treatment placed; noticeable swelling under the chin follows and can last several days or longer.

  2. Weeks 4–6

    Between sessions

    Swelling settles and the treated fat clears gradually; the next session is planned once settled.

  3. Around four sessions

    Across the course

    Reduction builds cumulatively, with change reviewed against photographs at each visit.

  4. After the course

    Final review

    The settled result is assessed and any remaining contributor, such as chin projection, is discussed separately.

Recovery

What is recovery like after fat dissolving injections?

Typical downtime: swelling under the chin for several days, sometimes longer, with tenderness. The specifics:

What's normal afterwards

  • Swelling under the chin for several days, sometimes into a second week
  • Tenderness and firmness in the treated area
  • Occasional bruising

What to avoid

  • Strenuous exercise for 24 hours
  • Massaging or pressing the area unless advised
  • High heat and alcohol for 24 hours

Risks and limits

What are the risks of fat dissolving injections?

No effective treatment is risk-free, and no treatment does everything. Knowing both sides is part of informed consent.

Possible side effects

  • Swelling, tenderness and firmness under the chin, which are expected
  • Bruising at injection points
  • Temporary numbness in the treated area in some patients
  • Rare nerve-related effects such as an uneven smile, usually temporary, minimised by careful technique

Limitations to understand

  • It only treats genuine, discrete fat, not skin laxity or chin projection
  • It cannot define a jawline that lacks structure underneath
  • A large fat pad is better referred for surgical reduction
  • Results build over a course; it is not a single-visit treatment

The alternatives

Fat dissolving injections compared with the alternatives

Fat dissolving injections vs chin and jawline filler for a 'double chin'

Fat dissolving injections

  • For a genuine discrete fat pad
  • Reduces localised fat gradually
  • Planned as a course of sessions

Chin and jawline filler

  • For weak projection or an undefined angle
  • Redraws the profile so the area reads slimmer
  • Often a single planned treatment

Which one The right choice depends entirely on the cause. Where the fullness is fat, dissolving is appropriate; where it is a recessed chin or an undefined jaw-to-neck angle, structural filler above the area is what actually improves it. The assessment decides, and sometimes the answer is a combination.

What it costs

What do fat dissolving injections cost?

You receive an itemised written quote at consultation, before committing to anything. The consultation is $75 for 45 minutes with Dr Rakib Uddin, redeemed against your treatment if you go ahead.

Confirmed at consultation once the cause is assessed and the course is planned.

What determines your quote

  • 01 The size of the fat pad
  • 02 The number of sessions the course requires
  • 03 Whether the area is treated alone or as part of a wider plan

You commit to nothing in advance: the consultation costs nothing and the quote is written before anything is booked. If the recommendation is not to treat, that advice is the whole appointment.

Afterpay acceptedZip accepted

Afterpay and Zip are available for treatment fees at the clinic, subject to each provider's own approval and terms.

About the practice

Expert questions

The questions worth asking about fat dissolving injections.

The questions that come up in the room, answered the way Dr Rakib answers them.

Which other areas can fat dissolving treat?

Under the chin is the most common area treated at the clinic, but the same treatment works on other small, discrete pockets of fat: bra fat, love handles and small areas of the abdomen among them. The pocket has to be small and clearly defined. It is not a treatment for general body fat and it is not a weight-loss treatment, so a consultation is necessary to confirm whether an area is suitable before anything is planned.

Do fat dissolving injections work for a double chin?

They can, when a discrete submental fat pad is genuinely the cause. Treatment is planned as a course, commonly around four sessions, with gradual reduction between them. They do not tighten loose skin or correct a recessed chin, and a large pad may be better served by surgery. The assessment sorts this out first.

How many sessions will I need?

Commonly around four, though it depends on the size of the pad and how you respond. Change is gradual and cumulative, so sessions are spaced several weeks apart and reviewed against photographs before the next is planned.

How long is the swelling?

Swelling under the chin is expected and can last several days, sometimes into a second week, especially after the first session. It is part of how the treatment works, and it settles between sessions.

What if my fullness is not actually fat?

Then this is not the right treatment, and you will be told so. A recessed chin, loose skin or an undefined jaw angle all create the look of a double chin, and each has its own approach. Dissolving fat that is not the cause does not help and can make loose skin look worse.

Is it permanent?

Fat cells that are broken down and cleared do not return, but significant weight gain can enlarge remaining fat cells in the area. A stable weight helps the result last.

Is it safe near the jaw?

In trained hands, placed precisely in the correct plane, it is a well-established treatment. It is doctor-performed here specifically because the submental area has structures that careful technique is designed to avoid.
