In recent years, cavitation is widely used in beauty and weight-loss areas. While the cavitation body contouring is booming, we find that there are lots of fake cavitation devices in the market. These fake cavitation machines only use simple ultrasonic (Ultrasound) technology and cannot really reach the treatment result of cavitation body shaping. To help consumers distinguish what true ultrasonic is and what the true cavitation is, and also help consumers buy real cavitation mahcines, we deliberately remind that please pay attention to the following misunderstanding when purchase.

1. Water Test Difference among True Cavitation, Fake Cavitation and Ultrasound

Ultrasonic cavitation slimming machine is mainly rely on the pressure produced by the  cavitation energy enabling water bubbles to cause the rapid expansion, then the pressure let water splash (the first picture below). What splashing out is the water droplets, not mist. Distribution of droplets is uneven, and the density is not large, so water splash is dispersed and intermittent. Ordinary ultrasonic is rely on the large area resonance of high frequency ultrasonic and produces large area water mist (the second picture below). It is characterized by the rapid phenomenon, large area, continued, uninterrupted and the formation of very fine mist. The intensity of the mist phenomenon is related to the power of the ultrasonic time around, the greater the power is, and the more obvious the mist phenomenon is. You can also see the mist phenomenon (the third picture below) in ordinary dozens of dollars 3M home use ultrasonic instrument. Many fake cavitation devices use ordinary high-powered 3M ultrasound and produce a strong mist phenomenon to deceive consumers. The structural differences between ordinary ultrasound and ultrasonic time around that can produce cavitation effect are as follows.

2. True Cavitaion Device and Fake Cavitation Device in the Market

In the cosmetology field, ordinary ultrasonic is mainly rely on the thermal effect. Ultrasound penetrates the skin, produce heat; the skin cells produce corresponding changes when the heat reaches a certain temperature. Ultrasonic cavitation is rely on the cavitation, the energy of cavitation effect is stronger and has a strong destructive on fat cells without damage to other organizations. It is difficult to destroy fat cells if simply relying on the heat effect of ultrasonic, but cavitation can be easily crushed fat. Therefore, if consumers spend hundreds of dollars to buy cheap fake cavitation, the last therapeutic effect is basically the same with home use ultrasonic instrument with only tens of dollars.
Now, there are many kinds of cavitation in e-bay. Here we warn customers that you should recognize the true cavitation before you make decision. Examples are as follows.

3.Penatration Depth among different Cavitation Frequency

In addition, the lower ultrasonic frequency is, the deeper the penetration depth of ultrasonic. Ultrasonic frequency of cavitation is lower than the normal ultrasonic, thus the penetration depth of cavitation ultrasound is deeper than the normal ultrasound, cavitation can reach the fat layer easily and act on the subcutaneous fat cells more efficient; thereby easily achieve a slimming effect. Ordinary ultrasonic energy is basically concentrated in the epidermis; it is difficult to reach the fat parts. The analysis of ultrasonic frequency penetration depth is as follows:
Note: fake cavitation discussed here is the market cavitation that use cavitation technology to disseminate treatment, but is only simple ultrasound, and cannot produce the cavitation effect.

4. Egg Experiment

The egg experiment of cavitation is as follows: normal ultrasonic cannot cause damage to eggs underwater, because it is difficult to reach fat parts of the egg underwater if it is simply rely on thermal effects: cavitation can easily reach the fat parts of the egg underwater and quickly break the fat parts.

5. Tin Foil Experiment

Underwater tin foil experiment is usually used to test energy intensity of cavitation, tin foil experiment is as follows, and the outbreak of the cavitation energy can easily penetrate the tin foil. Only cavitation can produce this phenomenon
