Fat Dissolving Injections
Fat dissolving injections are a non-surgical method that breaks down fat cells in targeted areas such as under the chin, lower abdomen, or thighs. The body gradually clears these cells over time. This treatment is not intended for rapid change or overall weight loss, but it can refine shape for people already close to their target. Results vary and take time, so having a plan and realistic outlook is important. A professional consultation is needed to determine whether this option aligns with your body type, timeline, and goals.
Fat dissolving injections use compounds naturally present in the body to break down fat cells. In Australia, there are currently two main versions: one produced by a pharmaceutical company and another prepared by compounding pharmacies. Both can be effective. They are most commonly applied to the jawline and under the chin. When used appropriately, the treatment can improve jawline definition and enhance overall facial proportion.
What are fat-dissolving injections?
Also known as injection lipolysis, fat-dissolving injections provide a non-surgical alternative for contouring. The procedure involves deoxycholic acid, a substance that targets and breaks down fat deposits. When injected into the treatment area, the compound dissolves stubborn fat cells, which the body then removes naturally. This makes it a focused method for reshaping areas such as the double chin or small, resistant fat pockets.
How do fat dissolving injections work?
Fat-dissolving injections work by targeting and breaking down stubborn fat cells in the area using a compound that mimics the body’s natural ability to process dietary fat. This compound disrupts the fat cell membrane, allowing the body to flush out the dissolved fat cells through metabolic processes.
The treatment involves a series of injections directly into the injection site, delivering a fat-dissolving product with precision. The number of sessions varies based on the amount of fat present in the treated area, with popular zones including submental fat, the lower face, and other areas of the body resistant to traditional fat loss methods. Once the fat cells have been destroyed, they do not regenerate.
Visible changes typically appear a few weeks post-treatment, with full fat reduction achieved over time. A long-term follow-up study showed that 90.4% of patients maintained fat loss results up to 12 months after their final session.
Who is a suitable candidate?
Fat-dissolving injections work best for individuals with small, defined areas of fat that persist despite exercise and healthy eating. They are not a substitute for weight management and are unsuitable for broad fat reduction. Candidates typically fall within a healthy weight range but want refinement of areas like the chin, jawline, or lower face.
Certain medical conditions, such as liver disease, uncontrolled diabetes, or clotting disorders, may limit suitability. Women who are pregnant or breastfeeding should not undergo treatment. A thorough assessment by a qualified doctor helps identify both eligibility and the safest approach for each patient.
Benefits of fat dissolving injections
Fat-dissolving injections provide a targeted option for reshaping zones that hold volume despite healthy routines. They offer a way to refine contours without surgical intervention. Common uses include treating the double chin or refining the lower face, though other areas such as the abdomen, thighs, and arms may also respond. Because fat cells are permanently destroyed, the effect can be long-lasting when combined with ongoing healthy habits.
Key points include:
- Reduction of fat in localised areas resistant to lifestyle changes
- Precise application to refine specific regions
- No incisions or scarring
- Support for balancing facial proportions
- Minimal recovery time for most patients
- Adaptable to different areas and body types
- Permanent fat cell destruction
- Useful for both small and larger deposits
- Complements rather than replaces healthy practices
- Non-surgical approach for those avoiding invasive procedures
Research in the Aesthetic Surgery Journal highlights how fat distribution changes with age, often increasing in the submental region. This supports the role of fat-dissolving treatments in restoring balance to facial contours.
What areas can be treated?
Fat-dissolving injections focus on regions where fat lingers despite lifestyle measures. They allow precise refinement of both facial and body contours. Common treatment zones include:
- Under the chin, to improve jawline definition
- The double chin, often linked to genetics or age-related changes
- Lower face, for improved symmetry
- Upper arms, particularly near the triceps
- Abdomen, for small resistant pockets
- Hips and flanks, to balance body lines
- Inner and outer thighs
- Bra line, above or below the strap
- Back, including lower sections or near the shoulder blades
- Knees, which may accumulate volume
Each case requires professional evaluation to ensure safety and effective planning tailored to individual anatomy.
What to expect during and after the treatment?
The procedure involves multiple small injections. Some discomfort may occur, though local anaesthetic can reduce this. Swelling and redness are common and may last from several days to two weeks. Effects develop gradually and can take two months or more to become clear. Treatment is often repeated at intervals until results are achieved. Clinical studies show most individuals notice visible improvement after two to four sessions.
Fat dissolving injections vs fat freezing
Both methods address localised fat but use different approaches. Fat-dissolving injections use a chemical process to break down fat at the cellular level, which the body then eliminates. This allows for precise targeting and tailored dosing. Fat freezing uses controlled cooling to damage fat tissue, which the body clears over time. While freezing can address broader areas in one session, injections may provide more focused results, particularly in smaller or firmer fat deposits. The most suitable method depends on factors such as fat distribution, body goals, and treatment preference, making professional consultation essential.
“Fat dissolving injections are medical procedures that require trained and experienced providers. In Australia, while they may not always require a prescription, they must only be performed after a proper medical assessment. The Cosmetic Physicians College of Australasia (CPCA) recommends face-to-face consultation with a doctor trained in cosmetic medicine, preferably a CPCA member. The procedure may be delegated to another healthcare professional but only under direct supervision. Clinics operating with medical oversight follow the standards that best protect patient safety and outcomes.“

Frequently asked questions about fat-dissolving injections
Who is a good candidate for fat-dissolving injections?
Adult men and women of any age. But ideal candidates for fat-dissolving injections are typically adults with moderate areas of stubborn fat who are not significantly overweight. This cosmetic procedure suits individuals aiming to reduce fat that doesn’t respond to exercise or calorie control. It’s important to understand that while injections that dissolve fat can significantly eliminate fat in specific areas, they are not a substitute for lifestyle improvements. You need to consult first to determine suitability and discuss the potential cost of fat-dissolving injections based on the specific targeted fat area.
What are the side effects?
As with any cosmetic injection, there are common side effects such as swelling or tenderness. Swelling is universal after treatment. There may be redness or bruising, aching, numbness, or tingling sensations are common and generally short-lived. If the treatment is misplaced, it may cause temporary nerve inflammation, causing weakness of the smile muscles or, if placed too deeply, difficulty breathing or swallowing. For these reasons, treatment should be performed by, or under the direct supervision of, an experienced doctor. Too aggressive treatment may potentially cause a loss of too much of the fat. Patients may encounter rare side effects associated with fat-dissolving injections, such as nerve injury or uneven texture in the treated area, particularly if larger areas of fat are addressed in one session. A professional cosmetic provider will discuss the risks or side effects during your consultation.
How much do fat-dissolving injections cost?
The injection costs vary based on the size of the treated area, the product used, and the number of sessions required. Smaller zones like the double chin typically fall on the lower end of the pricing scale, while treating larger areas of fat can increase the overall expense. The total cost of fat-dissolving injections also depends on the provider’s expertise and the complexity of the treatment plan. An in-person consultation provides a clearer breakdown based on your specific needs.
How many sessions do I need to see the result?
Results of fat-dissolving injections vary, and the number of sessions needed depends on the amount of fat in the selected area and how your body responds to the treatment. Most people require two to four appointments spaced several weeks apart. Each treatment with fat-targeting injections works progressively, and visible results typically begin to appear after the second session. Our CPCA-accredited doctors assess the areas of the body being addressed and recommend a schedule to help you achieve the desired results.
Will I be left with loose skin?
Generally, no. These treatments often have a skin tightening effect, particularly in the area beneath the chin and the lower face. These reduce the excess fat tends to force the skin to sit in a more curved position, causing further tightening. This natural retraction gives the skin a more defined and youthful appearance without added procedures.
Can other areas be treated?
Yes, but results are generally best in the jawline and under the chin. These treatments can also be effective in other areas of stubborn fat. Areas such as the arms, abdomen, or flanks can be considered if evaluated properly. A thorough consultation will determine if you are a suitable candidate for expanding treatment beyond the jawline.
