Hello, you need a more powerful machine for what you are talking about. You can choose our 80k 9in1. 

Recommended options: If you are mainly targeting the abdomen and arms, 40K is recommended because it has better penetration and is suitable for thicker fat layers. If you have a thinner fat layer or want to target detailed areas (such as the face or forearms), you can consider 80K. Additional advice When using radio frequency (RF), avoid getting close to the chest to avoid heating the silicone implants. If you use a laser pad (Lipo Laser), it can be used on the abdomen and arms, but still 

Use 1-2 times, 10-20 minutes each time. 

Hello, we can deliver to Canada. 

There is metal on the ears and the radio frequency head can be used on the face.

Hello, we ship worldwide. 

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.
