To reduce fat, people turn to eat less or exercise. However, it's challenging to carry them through, especially through workouts. Many people feel excited and confident initially, but they give it up halfway at last. Are there any other ways to achieve our goals? The answer is ultrasound cavitation.

Ultrasound is widely applied in beauty machines to remove localized fat. To this end, an ultrasonic cavitation machine stands out. It enjoys high popularity among people pursuing beauty. In a word, many people have benefited from the technology and procedure. An ultrasonic cavitation machine can apply a frequency of 30k (30,000 Hz), 40k, 60k, and 80k. So what are the differences? And how do ultrasonic cavitation machines with different frequencies affect fat removal?


What is ultrasound cavitation?

Ultrasound Cavitation

Before we go any further, it's necessary for us to have an idea about the concept: ultrasound. According to Wikipedia's explanation, ultrasound is sound waves with frequencies beyond the upper audible limit of human hearing. Ultrasound and audible sound are the same in terms of physical properties, except that humans cannot hear ultrasound. The lower and upper limits of frequencies audible to the human ear are 20 Hz to 20,000 Hz. However, ultrasonic devices utilize frequencies from 20 kHz to several gigahertz (as you can see from the diagram below).


How does an ultrasonic cavitation machine work?

How dose 40K Cavitation Machine works

Ultrasonic or ultrasound cavitation is a non-surgical and non-invasive method to reduce fat. An ultrasonic cavitation machine applies the principle of ultrasound. It uses an ultrasonic transducer to produce powerful sound waves. When the waves enter the body, they consume heat and moisture inside fat cells, resulting in their contraction. In addition, when the waves vibrate, they cause fat cells to generate a strong impact. The power exerts pressure upon the cells and bursts them instantly, which are treated by the lymphatic system and removed from our bodies via various channels. In this way, fat cells are becoming less and less. Therefore, fat removal comes true.


What are the differences between a 30 kHz ultrasonic cavitation machine and a 40 kHz one?

Before we go deep into this question, we should figure out some concepts first.

Four factors may impact the performance of an ultrasonic cavitation machine: ultrasound frequency, intensity mode, and time. Frequency is often indicated by Hz (hertz), MHz (Mega Hertz), and GHz (Giga Hertz). It illustrates how many ultrasound oscillations are emitted per second. For example, 1 MHz is 1 million oscillations per second. The higher the frequency, the shorter the wavelength; the shorter the wavelength, the lower the penetration depth. In short, the lower the frequency, the more powerful the energy it can generate.

A 30k ultrasonic cavitation machine performs better in penetrating power and directivity than a 40k one. Per the principle, the 30k one emits longer and more focused sound waves. This feature allows the waves to go deeper into the skin and maintain their strong power simultaneously. Thus, the former can deliver a better outcome if we use the two to remove a person's localized fat. Under the same conditions (for example, the fat thickness is the same), a 30k one saves more time and improves work efficiency. It also means we can attain the goal with less treatment time.

What are the targeted areas for ultrasonic cavitation?

The procedure works best on body parts with localized fat. Such body parts include:

  • Arms (to firm flabby and soft skin);
  • Abdomen (Remembered that you should not use the handpiece on its lower part, where the reproductive organs are located);
  • Sides and lower part of the back;
  • Legs (to eliminate fat deposits and cellulite and make legs slimmer);
  • Buttocks (to firm them).

Attention: It should not be performed on the heart, skeletons, or thin-skinned parts. Otherwise, it may trigger negative consequences, such as impaired blood circulation and painful sensations.


Who is not allowed to take the cavitation procedure?

If one of the following situations applies to you, you'd better keep away from it:

  • In pregnancy, lactation, menstruation, or surgical recovery;
  • With serious diseases, such as hypertension, heart disease, diabetes, severe thyroid, malignant tumors, etc.;
  • With skin disease or infectious disease;
  • Skin is in a sensitive or allergic period;
  • With wounds or just had liposuction;
  • With severe varicose veins or tumors;
  • Overaged people.


Introduction on the best ultrasonic cavitation machine

Cavitation 3.0 Best Cavitation Machine

Various ultrasonic cavitation machines are available in the market that can meet our needs, among which 30kHz and 40kHz ultrasonic cavitation machines are the favorite and first option for beauty salons or personal use. You can find some of the best cavitation machines from Suerbeaty, a professional beauty machine supplier and one-stop beauty treatment solution provider in Shenzhen, China.


The machine presented in the picture above is a 40k ultrasonic cavitation machine, one of the best of its kind with Suerbeaty. It adopts the same principle as mentioned above. Furthermore, it has a new ultrasonic transducer, high work efficiency, and low energy loss.

The difference between Mode A and Mode B for the handle

This is the latest FAQ


A:energy output continuously

B:energy output intermittently


A:energy output continuously

B:energy output only occurs after the handle fully touches the skin

Lipo laser:

A:The lamp beads continue to light up

B:The lamp bead flashes

C:The lamp bead flashes quickly

This explanation applies to most cavitation machines.


This article sheds some light on ultrasonic cavitation machines applying different frequencies and their effects on fat removal. It's a much better choice than liposuction, going on diets, exercising, among others. However, we should remember that a better effect on localized fat reduction can be achieved if we combine the procedure with vacuum therapy and RF machines. It will be a great honor for Suerbeaty if you find this article helpful to your life.
