RF treatments can tighten the skin. 

The 40k and 80k for cavitators refer primarily to the ultrasonic frequencies, which are 40 kilohertz (kHz) and 80 kilohertz (kHz)。 Frequencies around 30kHz to 40kHz tend to produce more audible sounds, which can be noticeable, especially for those sensitive to noise or with tinnitus. This is because lower frequencies fall within the human hearing range, causing a buzzing or ringing sound.In contrast, higher frequencies like 80kHz move outside the typical hearing range, reducing the likelihood of aggravating tinnitus. While 80kHz devices may produce a higher frequency sound, they are generally less audible. For those new to cavitation, both 40kHz and 80kHz devices can seem similar in use. However, if you're sensitive to sound, starting with an 80kHz device might be preferable. It's also worth noting that 40kHz machines are often more affordable. If you're undecided, we recommend starting with a 40kHz device, as it offers a balance between cost and effectiveness.

Hello, It is recommended to use 40k cavitation head three to four times a week, and each time for about 10 minutes on one part. And It is recommended to use the negative pressure head once a week. If you have sha on your back after doing it, do it a second time after recovery. The radio frequency head can be used every day. It is ok if the skin is slightly red. It usually takes 10 to 15 minutes. Each probe must be used with products, essential oils, lotions, creams, and gels are all OK. Do not dry burn the probe 

Tripolar head: For use on the eyes or face, recommended duration: 30 minutes; Quadpolar head: For use on the face/shoulders/arms, recommended duration: 30 minutes; Negative pressure head: For use on the shoulders, neck, arms, and legs, recommended duration: 5-10 minutes, until the sha effect is achieved. Fat-burning head recommended duration: 30 minutes. Note: While the negative pressure head can produce sha, it is recommended to wait at least one week for the affected area to heal before using it again. There are no specific requirements for other probes, but for optimal results, it is recommended to use them 3-4 times a week. 

Yes, the radio frequency head inside can achieve this effect.
