30K VS 40K Ultrasonic Cavitation

You must be aware of cavitation if not then you surely must have heard the name of this. Nowadays, ultrasonic cavitation has become much more popular because it is a non-surgical and easy way of getting rid of excessive fat. If you are not aware of this method, then you do not need to worry because we would be breaking down some of the details of this method.

In this post, we would be talking about ultrasonic cavitation, what it is, and what specific function it performs along with how it performs? We would also be casting a glance over the types of machines that are mostly used by a specialist which are 30K and 40K ultrasonic cavitation machines.


What is Ultrasonic Cavitation?

Ultrasonic cavitation is a non-invasive way of getting rid of fats from the parts of the body where exercise and diet are ineffective. The process of ultrasonic cavitation is harmless and easy on the body. Almost all the fat reduction machines set the frequency of ultrasound waves between 40 kHz to 5 MHz without causing any damage to other organs and parts of the body. The purpose of the procedure is to burn the extra fat in the body.

The ultrasonic cavitation machine uses a frequency of 40 kHz most of the time. The sound waves have a direct impact on the membranes of fat cells causing them to melt. During the treatment, the light buzzing of ultrasound is audible but it is not that high. However, the patient feels minimal discomfort because of the warmth over the skin.


The Process of Fat Reduction in Ultrasonic Cavitation

The ultrasonic cavitation machine's working principle is to reduce the fat by liquefying the deposits of fats that are then secreted through body wastes. This machine also works to stimulate tissues and collagen regeneration so that the appearance of cellulite can be reduced along with stretch marks. This also helps in the contouring of the body.


Limitations and Impact on Skin

In Ultrasonic Cavitation, there are no limitations when it comes to skin types. It can be performed on any skin. Nevertheless, if there are any wounds or sores in the area of treatment, the doctor might ask to delay the process until the wound is completely healed. This method of fat reduction is effective in collaboration with a healthy diet. This method is not a substitute for a healthy diet and exercise. In addition, this method only emptied the cells not destroyed them. So, if you do not take care of your diet then fats may get accumulated in the cells.

Talking about the impact on the skin, there might be the appearance of bristles and bruises but they are not permanent and do not cause any harm.

Now we would be looking at the types of machines that use different frequencies for ultrasonic cavitation. Different specialists use different frequencies, but two of the most common are 30K and 40k.


30K Ultrasonic Cavitation Machine

Ultrasonic cavitation machines are one easy way of getting rid of extra pounds of fats that are stubborn. Most of the machines use the frequency of 25 kHz to 40 kHz. So, the question arises which is better? A 30K cavitation machine is less powerful but it can work on deep layers of skin. A 30K machine can penetrate the subdermal layer and works magic on the skin by giving it a shape by contouring it. If anyone wants to get rid of fats quickly on specific parts of the body then 30K is the best option. However, when aestheticians have to provide long treatments, they do not prefer a 30K cavitation machine because of the intensity and power. However, this is not the matter that should be decided by the aesthetician because she or he will first investigate the skin and condition and then decide the things accordingly.


40K Ultrasonic Cavitation Machine

Well, as stated above ultrasonic cavitation is one of the best and most harmless ways of getting rid of fats and for that reason, a 40K cavitation machine is often used in the process. 40K machine does not penetrate the subdermal area like 30K machine. When the aestheticians have to do long treatments, they prefer 40K machines. Because of the demand, the 40K machines, you see in the market are counterfeit so be sure to buy from an authentic source so that you get good results.

40K machine emits strong ultrasound waves that vibrate the fatty cell rapidly that causing fat cytomembrane to burst inward which in return forces triglyceride to dissolve into glycerin and free fatty acids and then discharge from the body through the lymphatic system. In that way, the 40K machine is in the mainstream in the market of fat-reducing machines. The strong waves of the 40K machine directly hit the cells causing them to burst and getting rid of fats but not permanently as there is a danger of getting it back in case of not taking care of your diet. 40K is more common in the market as compared to 30K.



Ultrasonic cavitation is quite effective in reducing fat-causing any potential to any other organ. However, the results are not visible immediately after the process. It takes almost 6 to 12 weeks to witness the actual result of the procedure. However, this process does not destroy the fat cells but rather emptied them which means cells are capable of storing fat again. Therefore, a balanced diet is required to not gain fat again. However, the use of machines does have an impact on the process of getting rid of fatty cells. However, do not ever forget to consult your doctor or aesthetician before getting it done. Because skin type differs from person to person. Moreover, the pain capacity also varies so it is better to decide things first instead of regretting them later. Both machines vary in terms of price as well which depends upon the functioning of the machines and additional features.
