Hello, it is recommended to use it 3 to 4 times a week, and each use takes about 10 minutes. And it is recommended to use the negative pressure head once a week. It doesn't matter if the skin is slightly red. It usually takes 10 to 15 minutes. Each probe must be used with a product, essential oils, lotions, creams and gels are all OK. Do not dry burn the probe. 

For treating fibrosis, an 80kHz cavitation machine may provide more precision due to its higher frequency, which targets shallower layers and delicate areas effectively. Conversely, a 40kHz machine penetrates deeper, making it better for treating dense tissues. The choice depends on the depth and severity of the fibrosis.  

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.  

Of course, you can contact our after-sales customer service, this is his email: service@freyara.com. He will teach you how to buy it. 

It is not recommended that you do this, two to three times a week is fine, do not use it every day 

If you want more professional fat removal, we recommend you buy 6in1 or 9in1. 

Cavitation 40k operates at a frequency of 40,000 times/second. 80k can emit twice as many ultrasonic waves. The 80K cavitation weight-loss machine operates at a higher frequency than the 40K cavitation machine, noise is lower and the probe can generate heat. The choice of cavitation frequency depends on the desired treatment effect and the fat thickness of the area to be treated. But 40k low-frequency ultrasound is more suitable for dissolving deep, stubborn fat. 

Ultrasonic cavitation is a painless, non-invasive method of fat reduction. It uses ultrasound waves to break down fat cells in adipose tissue, targeting specific areas of the body such as the abdomen, waist, upper arms and buttocks. converted into free fatty acids and glycerine are excreted naturally through the body's lymphatic system. 

Yes, fat cavitation is a painless, safe and non-invasive procedure, used in Europe for decades and widely studied. What's more, since there are no incisions, there's no risk of infection or scarring after treatment. This allows patients to resume their normal activities quickly after treatment.
