When natural methods aren't enough
Reduce under chin fat the medical way.
Why this time, it’ll be different
We know how frustrating it is to struggle with stubborn under chin fullness. No matter how much you diet or exercise, that area often just won’t budge.
Your past efforts weren’t the full solution
You've tried natural methods, but under chin fat is resistant to these approaches. It’s not lack of effort, it’s about choosing the right treatment.
This isn’t vanity, it's identity
A defined profile is about more than just your appearance. It can help you feel more like yourself; comfortable with the person you see in the mirror.

Under chin fullness
Submental fat—that beneath the chin—is the most common cause of a double chin.
This fat is notoriously stubborn, often not responding despite diet and exercise, and even small amounts can create noticeable fullness.
Jawline
Under-chin fullness can be accentuated by a small or receding jaw bone.
Improving jawline structure using volume-based treatments can indirectly reduce the appearance of a double chin.
Chin
A small or recessed chin can make under-chin fullness appear more prominent by shortening the lower face and reducing forward projection.
Different approaches that project of your chin with volume indirectly reduce the appearance of a double chin.

Why do I have a double chin?
If you’ve struggled with under-chin fullness despite maintaining a healthy weight or lifestyle, you’re not alone — and it isn’t a personal failing. In many cases, a double chin is driven by anatomy, genetics, and natural ageing rather than effort alone.
Understanding what’s contributing to fullness in your case is the first step toward finding an appropriate medical solution.
It’s not always about weight
While changes in body weight can contribute to fat accumulation under the chin, many people experience under-chin fullness even at a stable or healthy weight. This is often due to genetics, where fat is naturally stored in the submental area and is resistant to diet and exercise.
For these individuals, lifestyle changes alone are unlikely to significantly alter the appearance of the area.
Facial structure plays a bigger role than most people realise
In some cases, a double chin can appear even when there is minimal excess fat or loose skin. A smaller or recessed jaw and chin can provide less structural support beneath the chin, allowing soft tissue to sit lower and create the appearance of fullness.
People with this anatomy often have a history of orthodontic treatment, such as braces, or wisdom teeth removal earlier in life.
Ageing changes the skin’s ability to hold its shape
As we age, the skin naturally loses collagen and elasticity. Over time, this reduces firmness and structural support, making the area beneath the chin more prone to sagging and less defined — even without significant fat accumulation.
Because under-chin fullness can have different underlying causes, there isn’t a single approach that works for everyone. Non-surgical medical treatments may be suitable for some people, depending on anatomy, goals, and tolerance for downtime and risk.
A confidential suitability assessment allows a clinician to evaluate what’s contributing to your under-chin fullness and advise whether treatment may be appropriate for you.
How it works
Non-surgical approaches to under-chin fullness focus on addressing the underlying contributors to a double chin — rather than simply masking its appearance.
The goal is not to dramatically change how you look, but to create a more balanced, defined profile that works with your natural facial structure.
Addressing fullness where it begins
In many cases, under-chin fullness is caused by fat that is resistant to diet and exercise. Non-surgical medical treatments work by dissolving this unwanted fat over time, allowing the area beneath the chin to appear more refined and defined.
Supporting the structure of the lower face
In other cases, under-chin fullness is influenced by a lack of chin and jawline support, rather than excess fat.
Treatment approaches focus on improving structural support along the lower face. By strengthening the foundation of the jaw bone, the appearance of under-chin fullness can be reduced indirectly, creating a more defined profile without directly treating the area beneath the chin itself.
Because under-chin fullness can develop for different reasons, the most appropriate approach varies from person to person. A suitability assessment allows a clinician to determine which factors are contributing in your case and whether non-surgical treatment may be appropriate.

Diet and exercise are always the first-line treatment options to reduce under chin fat. However, because it has a strong genetic component, many people rely on proven medical treatments to reduce their double chin.
To help make the process simple, we have developed an all-inclusive fixed price for our double chin treatments, regardless of method, extent, or number of sessions.
So that we can provide pricing information, you need to speak to our clinicians so they can determine if it’s right for you.
Due to Australian Therapeutic Goods regulations, we are unable to discuss specific treatment options or brands until your suitability has been assessed by one of our practitioners.
Most people undergo 2-4 sessions. The number of treatments depends on the degree of fullness, your treatment plan, and how the fat responds to the procedure.
Most people notice very little sensation during treatment.
While everyone’s experience will be different, we always follow a comprehensive treatment process designed to maximise comfort.
This involves using various numbing methods, as well as a refined treatment technique.
Our goal is to have you feel as little as possible during the process.
Most treatments are completed in under 5 minutes. However, appointments are typically 15-30 minutes, to allow time for proper planning, numbing, and to answer any questions you may have before or after the treatment.
Result gradually develop over 4-6 weeks as the treated fat is cleared by the body.
As the treatment breaks down fat cells, the results are permanent. To maximise your results over the long-term, you should aim to maintain a consistent weight and healthy lifestyle.
Future weight gain may cause remaining fat cells to increase in size, although you’ll put less fullness on here compared to before treatment.
After treatment, it’s normal for the area to feel swollen, slightly red, and tender as the numbing wears off. These effects typically settle within a few days.
Over the following weeks, the area may feel firm or numb — a normal part of the process and a sign the treatment is working. By around week four, this sensation usually eases, and early results become visible. At this point, your clinician can help determine whether an additional session would be beneficial.
Double chin treatments are generally considered safe when performed by qualified medical professionals.
Common side effects include swelling, redness, and tenderness at the treatment site. These effects are temporary and usually resolve within a few days.
As with all medical and cosmetic treatments, there are risks involved. Your clinician will discuss these with you in detail during your appointment to ensure you can make an informed decision.
Rare side effects may include infection or temporary weakness of the lower lip. These effects are uncommon and are typically short-lived.
Before proceeding, your clinician will discuss all potential risks and considerations with you in detail, ensuring you can make a fully informed decision about your treatment.
