If you have stubborn fat that will not shift no matter what you do, ultrasound fat cavitation might be the treatment worth looking at.
It is a non-surgical body contouring treatment that uses ultrasound waves to break down fat cells in targeted areas. No needles, no anaesthesia, no downtime. The broken-down fat is processed and removed by your body naturally over the following days.
At Hourglass By Design in Clarkson, Perth, fat cavitation is one of the core treatments we offer. We specialise in non-invasive body sculpting, so this is not a side offering. It is something we do regularly and know how to get results from.
Here is what you need to know.
Fat cavitation uses low-frequency ultrasound waves to target fat cells underneath the skin. The technology is straightforward and has been used in clinics around the world for years.
A handheld device is moved over the treatment area. It sends ultrasound waves into the fat layer beneath your skin. These waves create tiny bubbles inside the fat cells, which cause the cell walls to break apart. The fat inside is released as a liquid.
You might hear a slight buzzing or humming sound during the treatment. That is the ultrasound frequency at work. It is normal and nothing to worry about.
Once the fat cells are broken down, the liquid fat is picked up by your lymphatic system and processed out of your body over the following days. This is why drinking plenty of water after your session matters. It helps your lymphatic system do its job more efficiently.
The fat cells that are broken down are eliminated permanently. But like any body sculpting treatment, the remaining fat cells can still expand if you gain weight. Maintaining a stable, healthy lifestyle after treatment helps you keep the results.
Ultrasound fat cavitation works well on areas where fat tends to accumulate and resist diet and exercise. The most commonly treated areas include the stomach and waist, love handles and flanks, inner and outer thighs, upper arms, bra line and back fat, and buttocks.
The treatment is particularly effective on softer fat. If the area has pinchable, soft fat sitting under the skin, it is usually a good candidate for cavitation.
One of the added benefits of cavitation is that it can help reduce the appearance of cellulite. The ultrasound energy smooths the fat layer underneath the skin, which improves the texture and appearance of areas like the thighs and buttocks. It is not a dedicated cellulite treatment, but many clients notice visible improvement in skin smoothness alongside the fat reduction.
Like all body sculpting treatments, cavitation works best on the right candidates.
Fat cavitation is a good fit for people who are at or close to a healthy weight but have localised pockets of stubborn fat, who want a non-invasive alternative to liposuction, who are looking for gradual, natural-looking results, and who are willing to maintain a healthy lifestyle after treatment to keep the results.
It is not a weight loss solution. If you are looking to lose a significant amount of weight, cavitation is not the right starting point. It is designed for body contouring and reshaping specific areas.
Fat cavitation is not suitable if you are pregnant or breastfeeding, if you have metal implants in or near the treatment area, if you have liver or kidney conditions (since the fat is processed through your body’s filtration system), if you have active skin infections or open wounds in the area, or if you have a pacemaker or heart condition.
Fei will screen for all of this during your consultation before any treatment begins.
Most people find fat cavitation comfortable and relaxing. A gel is applied to the treatment area, and the handheld device is moved in circular motions over the skin. You will feel a gentle warmth in the area. Some people hear a low buzzing sound, which is the ultrasound frequency. It is not painful.
A typical session lasts between 30 and 60 minutes depending on the size of the treatment area.
There is no downtime. You can go straight back to your normal activities. Some people notice the treated area feels slightly warm for a short time after, but that settles quickly. There is no bruising, swelling, or recovery period.
Light exercise after your session, even a walk, helps your lymphatic system process the broken-down fat cells more efficiently.
Most people need between 6 and 12 sessions for the best results, with sessions spaced about one week apart. The exact number depends on the area being treated, the amount of fat, and your individual goals.
You may notice some changes after the first few sessions. Measurements often change before the visual difference becomes obvious in the mirror. By the midpoint of the course, most people see noticeable improvements.
Your consultation will give you a realistic idea of how many sessions to expect. Fei will assess the area and build a treatment plan based on what your body needs.
Both treatments reduce fat, but they work differently. Fat freezing uses controlled cold to crystallise and destroy fat cells. Cavitation uses ultrasound to break them apart. Fat freezing tends to work better on denser, more defined fat pockets. Cavitation can be more effective on softer, broader areas and is often used alongside fat freezing for a more thorough result.
Some clients use cavitation first to break up the fat layer, then fat freezing to target what remains. The two treatments complement each other well.
Laser lipo uses laser energy to break down fat cells. It tends to work well on smaller, more precise areas. Cavitation covers a broader surface area and is often chosen for larger zones like the stomach or thighs. Both are non-invasive with no downtime.
One of the most popular combinations at Hourglass By Design is cavitation followed by RF skin tightening. Cavitation reduces the fat. RF tightens and firms the skin in that same area. If you reduce fat without addressing skin laxity, the area can look loose. Adding RF to the plan gives a more complete, defined result.
Hourglass By Design is a specialist non-invasive body sculpting clinic. Fat cavitation is not an afterthought or an add-on to a beauty menu. It is one of our core treatments, and we know how to get the most out of it.
Our clinic is located in Clarkson in Perth’s northern suburbs. We serve clients across Joondalup, Mindarie, Quinns Rocks, Wanneroo, Butler, and the wider northern corridor.
Fei, our body sculpting specialist, builds a personalised plan for every client. That includes assessing which treatment or combination of treatments will give you the best result. If cavitation is right for you, great. If something else would work better, she will tell you.
We offer the full range of non-invasive body sculpting treatments including fat freezing, HIFU, EMS body sculpting, vacuum therapy, and more. That means your plan is never limited to one option.
Drink plenty of water in the 24 hours leading up to your appointment. Good hydration helps your lymphatic system work efficiently after treatment. Avoid heavy meals and alcohol before your session. Come with comfortable clothing.
Keep drinking water. This is the single most important thing you can do after cavitation. Your body needs to flush the broken-down fat, and water is what makes that happen.
Light exercise like a walk or gentle movement helps too. Avoid alcohol for 24 to 48 hours after treatment, as your liver is already working to process the released fat.
A clean, balanced diet in the days following your session supports the process. Nothing extreme, just give your body what it needs to do the work.
Does fat cavitation hurt?
No. Most people describe the treatment as warm and relaxing. You may hear a low buzzing sound from the ultrasound frequency, but there is no pain involved.
How quickly will I see results?
Some people notice measurement changes after the first few sessions. Visual changes typically become noticeable after 4 to 6 sessions. Results continue to improve throughout the full course of treatment.
Is fat cavitation the same as fat freezing?
No. Cavitation uses ultrasound waves to break down fat cells. Fat freezing uses controlled cold to crystallise and destroy them. Both are effective but work differently. Some clients benefit from combining the two.
How long do the results last?
The fat cells that are broken down and eliminated are gone permanently. But the remaining cells can still grow if you gain weight. A stable, healthy lifestyle keeps the results in place.
Is there any downtime?
None. You can go straight back to your normal routine after every session.
Can I combine cavitation with other treatments?
Yes. Cavitation works especially well when combined with RF skin tightening to address both fat reduction and skin firmness. It also pairs well with fat freezing for a more comprehensive body sculpting approach.
How many sessions will I need?
Most people need between 6 and 12 sessions, spaced about one week apart. The exact number depends on the area, the amount of fat, and your goals.
Who should not have fat cavitation?
Cavitation is not suitable during pregnancy or breastfeeding, for people with metal implants in the treatment area, for those with liver or kidney conditions, or for people with pacemakers. Your consultation will cover all of this before any treatment starts.
If you have stubborn fat that diet and exercise are not shifting, ultrasound fat cavitation could be the right next step.
