CoolSculpting vs. Ultrasonic Cavitation (Fat Cavitation Machine)

Whether it’s for vanity or health reasons, no one wants to carry around excessive stubborn fat. However, there are many other ways of losing this fat for those who have tried weight loss regimes and don’t see results, such as surgical contouring and other mildly invasive procedures to remove extra fat.  

Most people aren’t too keen to go under the knife. So if you’re one of them and are looking for a more non-invasive technique to get rid of extra fat from the body, we have two exciting technologies here for you today – CoolSculpting and Ultrasonic Cavitation.

This article will address everything you need to know about these two fat-removal options and hopefully help you pick the best non-invasive procedure for your body.

What is CoolSculpting?

CoolSculpting is a non-surgical procedure that utilizes cooling to reduce and remove body fat. More specifically, it freezes fat cells in a specific targeted area which destroys them with time; hence it is not a full-body fat reduction option.

The most common targeted areas for CoolSculpting are the back, arms, and chin, since reducing fat from these areas via diet and exercise is usually quite difficult.

What is Ultrasonic Cavitation?

Another popular non-invasive fat reduction procedure is Ultrasonic Cavitation, also called ultra-cavitation. As the name implies, this method utilizes infrared/ultrasonic waves to destroy fat cells in specific targeted areas.

Ultrasonic cavitation is ideally used for the belly, upper arms, thighs, love handles, and chin.

CoolSculpting vs. Ultrasonic Cavitation: The Similarities

CoolSculpting and ultrasonic cavitation are suitable treatments for removing stubborn fat from areas often not affected by diet and exercise. So first, let’s look at their similarities.

Body Contouring

Since both methods focus on targeted areas, they help enhance the overall contour and shape of the body so you can attain a curvature of your liking.


As mentioned, both methods are non-invasive and low risk of post-infection – no incisions or openings made. No anesthesia is required as well since there is minimal discomfort during the procedure.

And with no downtime after the treatment, you can swiftly go back to work and resume your daily activities.

In-Clinic or At-Home

While CoolSculpting is generally performed in a doctor’s clinic using larger machines, smaller portable units are also available for at-home procedures. For instance, the Igia Fat Freezer Platinum is a good option for performing CoolSculpting in the comfort of your own home.

Similarly, ultrasonic cavitation is usually performed at a salon, but various affordable home ultrasonic cavitation machines are available. For instance, RF Radio Frequency Skin Lifting Body Slimming Beauty Machine for Women provides multifunctional body shape care.

Quick Treatment Sessions

Based on how many target areas you want fat removed from, both procedures usually take 30 minutes to an hour. That means you can easily schedule the procedures during a lunch break or before going to bed if you’re using an at-home device.

Won’t Inhibit Body from Storing fat

Even though both procedures help you eliminate excess body fat, they do not stop the body from storing more fat or gaining weight after the procedures. The latter will still be determined by diet and exercise.

CoolSculpting vs. Ultrasonic Cavitation: the Differences

Now that we’ve covered the similarities, here are a few differences between the two procedures.

Mode of Action

As we’ve mentioned briefly in the introduction, the main difference between CoolSculpting and ultrasonic cavitation machines is the reaction they produce to the excessive fat in the body.

In CoolSculpting, cold temperatures provoke a reaction within the fat cells by freezing and damaging them. Once this is done, other cells work on them and ultimately remove them from the body. However, if the body needs to store more fat, it will choose other regions where fat cells are still available and expand and fill the area with fat again.

On the other hand, ultrasonic cavitation utilizes low-frequency ultrasonic waves/infrared waves to ‘liquefy’ the fat present within the cells. This liquefied fat is then released into the bloodstream, and eventually, it is disposed of by the lymphatic system. So in this procedure, actual fat cells remain intact and can grow in size if more fat is stored via poor weight management.

Time Taken to See Results/Longevity of Results

CoolSculpting can take about 1-3 months to deliver results. Even though the fat cells are damaged by cold temperatures, they are not immediately removed from the body. However, the results are more permanent since the damaged fat cells are entirely removed from the targeted area, and the latter is less likely to store more fat in the future, even with weight gain.

On the other hand, ultrasonic cavitation provides more instant results (within days) since the fat inside cells is immediately liquefied and spontaneously removed by the lymphatic system. However, if you don’t watch your weight, your cells will easily fill with fat. So the results are not as long-lasting as those from CoolSculpting.

Side Effects/Comfort Level

Both procedures are non-invasive, but CoolSculpting still offers some discomfort because of the cold temperature, along with some temporary cramping, itching, stinging, tenderness, or bruising.

Ultrasonic cavitation is more comfortable, and most people find the little heat from the ultrasonic waves comfortable. A slight reddening of the area is temporary and not painful at all. The procedure might accompany a buzzing sound which can be a little annoying but is generally tolerable.

Conclusion: Which Option Is Better?

CoolSculpting and ultrasonic cavitation are viable, non-invasive, and safe options for removing and reducing excessive body fat from notoriously tricky areas of the body.

In selecting between CoolSculpting and ultrasonic cavitation, you must decide whether you want immediate or more permanent results. But in both cases, the treatment will be beneficial if you maintain your weight and avoid storing excessive fat in your body.

Frequently Asked Questions

1. Can ultrasonic fat cavitation increase your poop?

Ultrasonic cavitation liquefies fat within cells and releases them into the bloodstream to be removed from the body. This could cause some minor changes in the color and consistency of your urine or stool. However, the procedure will not make you poop more than you usually do.

2. How much fat does CoolSculpting remove?

Coolsculpting can efficiently help remove up to 25 percent of fat cells in the targeted area.

3. Does ultrasonic cavitation destroy fat cells?

No, ultrasonic cavitation simply liquefies the fat inside fat cells. However, the cells remain intact and can still store more fat.
