6 Best Cavitation Machines in 2023

For those of us who are aspiring to slim down and reduce stubborn fat, it’s very exciting see the inches of fat melting away following a cavitation treatment session at the spa.

Going to the gym involves a lot of effort and time.  Enjoying a session at the spa is simply much more relaxing, and the great thing is that cavitation can achieve the same results as your sweaty gym workout!

Yes, ultrasonic cavitation is a salon treatment that can deliver remarkable body slimming effects.  But there are so many cavitation machines on the market.  Which ones are the best in 2023?

What is an Ultrasonic Cavitation Machine?

Before we discuss which machines are the best in the marketplace, we should understand exactly what is an ultrasonic cavitation machine?

Ultrasonic cavitation, is a popular and essential body slimming treatment available in spas and clinics worldwide.  The treatment works by sending low frequency ultrasound waves through the skin, deep into the fat layer.  The waves put pressure on the fat cell membranes, causing them to burst.  The destroyed fat cells are then removed from the body naturally via the metabolic system over the coming weeks.  The procedure is completely non-invasive and requires no down-time.

Obviously ultrasonic cavitation is a great way to achieve permanent fat reduction painlessly without extra diet and exercise.  And an ultrasonic cavitation machine is exactly the tool you need to make it happen.

Features to Consider when Shopping for an Ultrasonic Cavitation Machine

While there are a lot of cavitation machines on the market these days, not all are created equal.  Now we will explore what features you should consider.


Most cavitation machines offer multiple technologies.  The name on the label may simply say “Cavitation Machine”.  But typically there will be additional complimentary body contouring technologies available on the machine.  The most frequently combined technologies are radio frequency, vacuum therapy, lipo laser, ems, cold hammer, and micro-current photon-therapy.   These technologies can make the fat reduction process more effective and can also help with skin tightening and lifting.

If you are using the cavitation machine for professional use, these additional functions can be quite useful, as they allow you to create more customized treatment programs for your clients.

Ultrasonic Frequency 

Any wave with a frequency that is greater than the limit of human hearing ability (about 16 KHz) is considered ultrasonic.  Most ultrasonic cavitation machines on the market are either 80KHz, 40KHz, 30KHz, or 20KHz, with 40KHz being the most common.  

Frequency and wavelength have an inverse relationship.  Therefore, lower frequency ultrasonic waves have longer wavelengths and can reach deeper into fat layers than the higher frequency ultrasonic waves.  This is something to consider if you or your clients have thicker layers of fat.


Depending on the power output of the cavitation handle, fat loss results can be achieved more or less rapidly.  To achieve significant fat loss within the first several sessions, look for a power output of greater than 50W such as our 9 in 1 Cavitation Machine for Toning & Slimming, with 90W.  And beware that, unfortunately, some advertisers may be offering misleading or incorrect specifications.

Ease of Use

Most cavitation machines feature a touch screen display.  Make sure that it is easy to operate.  Also make certain that the handles are easy to hold and maneuver.  Plastic handles are lighter weight, but metal handles can be easier to control.

Some cavitation machines offer 2 or more technologies in the same treatment handle such as our “S-Shape” cavitation machines (example: S-Shape 30K Cavitation Machine with Lipo Laser), which can save you time.  However, if you want the most effective results, it’s better to do the treatments separately.  For example, by first doing radio frequency treatment on the targeted body area, the fat cells become fully activated, which will optimize the subsequent cavitation procedure. 


There is wide range of cavitation machine prices.  There are many high quality machines available for $200~$3000.  If a portable cavitation machine you are looking at costs more than $3000, you may be simply overpaying, or you may be paying to support marketing and showroom costs.


Depending on where you purchase your machine, you may get or may not get a good warranty.  All warranties are not the same, so it’s better to read the seller’s policies to fully understand what’s included.  If spare parts need to be replaced, who will be responsible for shipping costs?
