When it comes to ultrasound cavitation, many of us are confused by numbers like 30K, 40K, and 80K. Is a 30K cavitation machine better than a 40K machine, or does a higher number mean a better effect? Don’t get frustrated; you are not alone. In this piece, we’d like to share more information about cavitation machines to help you select the best machine based on your individual needs.
What do 30K, 40K, and 80K actually mean?
To figure out which type is the best choice for you, we first need to understand what these numbers mean. They refer to the frequency of the ultrasound waves emitted by the machine during treatment. A cavitation machine uses a powerful sound-wave head that emits waves at a specific frequency. These waves create a strong impact on the body's fat cells and create frictional movements between them. This process helps break down fat cells and consume heat and water from the cells, leading to the shrinkage of fat cells. Moreover, when the sound-wave vibrations create strong cracks between the cells, they can burst, helping to achieve a slimmer look. While these machines selectively destroy low-density fatty tissue, they protect high-density tissue such as blood vessels and nerves.
The key difference between 30K, 40K, and 80K cavitation is the frequency of ultrasound waves they emit. For instance, 80-kilohertz cavitation pulses 80,000 times per second, while 30-kilohertz cavitation pulses 30,000 times per second. As for the difference in treatment effect, a higher number doesn’t necessarily mean better treatment. Just because you are getting 80,000 ultrasound waves in the targeted area doesn't mean they will penetrate as deeply as waves at the slower 30K frequency. It may sound a little confusing. In simple terms, a slower frequency may be more effective because the slower the frequency, the deeper the waves penetrate. To help your clients dissolve thicker layers of fat, 30K and 40K cavitation machines perform better than 80K cavitation machines.
Why do I feel warmth during higher-frequency cavitation treatment?
People who opt for 80K cavitation may feel warmth in the treated area during the procedure. That warm feeling may go away when they switch to a 40K or 30K treatment. As mentioned earlier, an 80K cavitation machine emits 80,000 ultrasound waves through the handle per second, which can cause the handle to warm up during use. Conversely, with lower-frequency cavitation machines like 40K and 30K, the handle usually stays cool, as the cavitation process itself does not produce heat. The cavitation handle may also produce heat if it has a built-in radio frequency (RF) feature. RF technology is designed to heat the deep layer of the dermis, which can result in a warm sensation during treatment.
Does lower-frequency cavitation cause louder squeals in the ears?
The high-frequency sound-wave power of cavitation machines is incredibly strong. Sound waves with a frequency higher than 20 kHz act on the fat layer 20 mm deep under the skin through high-frequency sound-wave focusing. The concentrated energy creates friction and heat among the fat cells in the focal area, breaking them down and emulsifying them. This process emits sound, which can cause tinnitus.
So, whether it is 30K, 40K, or 80K, tinnitus can occur. However, some users report hearing less noise in their ears as the frequency increases, so 80 kHz may bother them less. At the same frequency, some people hear just a buzz while others hear a loud squeal. That is something to consider if you are sensitive to noise during body sculpting or contouring. At the same time, advances in technology have helped minimize loud squeals in cavitation machines, so nowadays you can have cavitation treatment at any frequency without worrying about tinnitus.
How do you choose the best cavitation machine?
When choosing the best cavitation machine for you, there are many options to consider. With so many machines and features available, it can be overwhelming to decide which one will bring you the best results. To start, take a good look at your body in the mirror. Do you have large areas of fat or sagging skin that you want to address? If so, a stronger cavitation machine with integrated radio frequency, such as a 30k S Shape Cavitation Machine, is your best option. If you have smaller areas of fat, then go for a 40K; it is an all-around product that will take care of smaller areas. If you don't have areas of fat to target, you can go for a 60K or 80K.
There are also other treatments you can combine with cavitation, such as microcurrent and LED for product absorption and muscle toning, including tightening the muscles in the face, and RF skin tightening along with vacuum therapy to tone and tighten the skin. Choose based on your situation: learn about your body first, then make the best choice.
Do you need conductive gel for cavitation treatment?
Cavitation is a simple procedure that shapes your body in areas including the stomach, thighs, and arms. However, if you want even better results, consider using conductive gel during your session. Gels are beneficial since they protect and hydrate your skin while also extending the life of your cavitation device.
