Do ultrasonic liposuction cavitation slimming machines work?

There are a number of devices on the market that can reduce fat in areas of the body.  The method that caught your eye is not as widely used as other devices, such as Coolsculpting.  The devices do not work in the same way as liposuction, where the fat is removed surgically.  Rather they affect the fat cells in a manner that causes them to absorbed by the body over time.  Liposuction is always the best option.  You may need several treatments to get the result that you want.  After several treatments, the cost could approach that of liposuction.  If you are interested in a non-invasive option, I would consider Coolsculpting as it has the longest history on the market and has a very good safety record.Aloha,Shim Ching, MD

Ultrasonic liposuction cavitation slimming machines are marketed as non-invasive treatments that use low-frequency sound waves to break down fat cells, which are then eliminated by the body's lymphatic system. While some users report temporary reductions in fat and circumference in treated areas, scientific evidence supporting the long-term effectiveness and safety of these devices is limited.
It's important to have realistic expectations; these treatments might offer modest fat reduction but are unlikely to produce significant weight loss or permanent body sculpting results comparable to surgical liposuction. Factors like diet, exercise, and genetics play crucial roles in the treatment's effectiveness.
For persistent areas of fat, liposuction remains the gold standard for effective treatment.

Thank you very much for your very relevant and up-to-date question. There are now numerous ways of removing fat besides the traditional liposuction. It is important to know that procedures like liposuction Cryolipolysis  or ultrasound cavitation are by no means procedures to lose weight but only to remove stubborn fat in small areas to shape the body. These non-invasive procedures do work. In terms of efficacy of these procedures it has to be noted that cold works better than hot!That means fat freezing works better than cavitation. It is not unusual for cavitation treatments to have to be repeated more than 10 times where as Cryolipolysis normally will be repeated about 4 to 5 times. But none of the non-invasive treatments are as effective as the classic liposuction. Have a wonderful rest of the day and greetings from the beautiful island of Jamaica.

Hi, if you are relatively fit then you are a good candidate
for #Vaser liposuction. It is a minimally invasive way to get
rid of stubborn fat and a good option for your abdomen/waist as this
procedure is easier to sculpt and contour the body. You can even add
a fat transfer procedure after. Common uses are for breast
augmentation and Brazilian buttock lift depending on the amount of fat harvested. 
Please remember that liposuction is NOT a method of weight loss
and muscle toning, or an alternative to diet and exercise. It does not
affect one's metabolism. Regular exercise and diet is still recommended in
maintaining good and lasting liposuction results. Find a board-certified
plastic surgeon and discuss realistic goals and expectations. Best of
luck! #RealSelf100

Non-invasive machines work to a degree, depending upon the device and the patient response. However, usually multiple treatments are required which adds to cost and prolongs overall recovery/result time. They also do not appreciably tighten skin.Liposuction is a proven, one time treatment for fat removal, skin tightening (with Vaser ultrasound or Smart Lipo laser) and potential fat transfer. Recovery is predictable.An exam and consultation with a plastic surgeon is recommended to discuss your options and expectations.

If you have money to burn and don't really care about getting any improvement, then getting ultrasonic cavitation is made for you.

This is unlikely to get you the results you want. For best results, I recommend a hi definition procedure like VASER liposuction. I use VASER HI DEF with ThermiRF and fat grafting to get the most fat removal, skin tightening, contour and definition. This combination will give you the most toned result. I recommend getting a formal evaluation with a hi definition physique expert. Best, Dr. Emer

If you are trying to loose 3-5 inches the chances of doing it non-invasively are probably low unless you plan on multiple treatments. You will probably get a quicker more predictable result if you go ahead and have some form of surgical liposuction.
Good luck,

Aloha and thanks for your question. While modern medicine is always coming up new and better ways to treat many problems, there really isn't a better alternative to traditional liposuction! Although it is 'invasive', it can often be done under local anesthesia with minimal pain/recovery. The results are generally better than these other alternatives and at significantly less cost. It would be best for you to visit an experienced board certified  plastic surgeon for an in-depth consultation to review your options.   Mahalo, Dr D

There are three major energies used to reduce fat non invasively. Negative thermal energy, freezing, via CoolSculpting has been the leader in non invasive fat removal for fat above the stomach wall and underneath the skin. It, nor any other technology that is non invasive, can not reduce the fat that is below the stomach wall. Ultrasound, or ultrasonic energy via cavitation, has been used by UltraShape and recently they have developed a more powerful unit as their initial unit was not powerful enough to create significant improvement compared to that which I saw consistently with CoolSculpting. SculpSure uses light energy of one wavelength, 1064nm., as a laser to heat the fat.I need more time to assess the effectiveness of both the ultrasound UltraShape unit and SculpSure to see if it can reduce fat as well as CoolSculpting.

There are number of devices on the market that work in different ways to decrease the amount of fat. When evaluating any new technology, you may consider going back to realself to read patient reviews. Look at before-and-after photos posted by people who had that specific treatment. Evaluate the results and see what they have to say about their satisfaction with the procedure.
