Frequently Asked Question
What Is Ultrasonic Cavitation?
Ultrasonic Cavitation Machine is a beauty device that uses low-frequency ultrasonic cavitation technology to target the fat layer beneath the skin. It is widely used in body contouring , localized fat reduction , cellulite reduction, skin tightening, and professional slimming treatments in beauty salons and home-use aesthetic devices.
When ultrasonic energy is delivered into the subcutaneous fat tissue, it creates a cavitation effect (Cavitation Effect), producing microscopic bubbles that help disrupt fat cells. These fat cells are then gradually processed and eliminated through the body’s natural metabolic system.
In addition, many advanced devices combine radio frequency (RF Skin Tightening), vacuum therapy (Vacuum Therapy), and EMS muscle stimulation (EMS Muscle Stimulation) technologies. This combination helps improve body contours, enhance skin firmness, and promote a smoother and more refined skin appearance.
What Is the Working Principle of 40K and 80K Ultrasonic Cavitation Machines?
The 40K Ultrasonic Cavitation Machine and the 80K Ultrasonic Cavitation Machine are both beauty devices that use Ultrasonic Cavitation Technology for body contouring and localized fat reduction .
The main difference between the two lies in their operating frequency. As a result, they differ in energy penetration depth, treatment precision, and suitable treatment areas.
The 40KHz ultrasonic cavitation machine delivers 40,000 ultrasonic vibrations per second, transmitting energy into the subcutaneous fat layer.
This ultrasound energy generates microscopic bubbles within the fat tissue, creating a cavitation effect (Cavitation Effect). These bubbles help to disrupt fat cells in targeted areas.
Because the 40K frequency is relatively lower, it provides stronger penetration capability, making it more suitable for treating larger body areas such as the abdomen, waist, thighs, and buttocks.
The 80KHz ultrasonic cavitation machine delivers 80,000 high-frequency ultrasonic vibrations per second, allowing energy to be transmitted more evenly to the targeted treatment area. Because the frequency is higher, the ultrasound wavelength is shorter, resulting in a more precise and refined treatment effect, and the overall procedure is typically more comfortable.
The 80K technology is commonly used in advanced body contouring and high-end aesthetic treatments. It is particularly suitable for users who require a higher level of comfort and more precise body sculpting results.

Ultrasonic Cavitation Machine Usage Steps
1. Clean the Treatment Area
Before using an ultrasonic cavitation machine, thoroughly clean the treatment area to ensure the skin surface is free from oil, sweat, and impurities. This helps improve treatment effectiveness and ensures better energy transmission.
Suitable Treatment Areas:
- Abdomen contouring
- Waist slimming treatment
- Thigh contouring
- Arm firming
- Buttocks shaping
- Back contouring
2. Apply Conductive Gel
Apply an even layer of ultrasonic conductive gel to the treatment area. This helps improve ultrasound energy transmission and ensures smoother device movement during the procedure.
Functional Benefits:
✔ Improves energy transmission efficiency
✔ Enhances probe contact with the skin
✔ Increases treatment comfort
✔ Protects the device probe from friction and wear
3. Activate the 40K or 80K Ultrasonic Probe
Select the appropriate mode based on the treatment needs.
40K Ultrasonic Cavitation Mode
How to Use:
Place the probe firmly against the skin and move it slowly in circular motions. Avoid keeping the probe in one position for too long to ensure even energy distribution and safety.
Recommended Treatment Time:
15–30 minutes per body area
RF Radio Frequency Treatment (If Supported by the Device)
Many ultrasonic cavitation machines are also equipped with RF (Radio Frequency) technology to enhance overall treatment results.
- RF Skin Tightening
- Radio Frequency Therapy
- Skin Firming Treatment
- Collagen Stimulation
- Anti-Aging Care
Recommended Treatment Time:
10–20 minutes per treatment area
5. Hydration and Aftercare
After the treatment, it is recommended to:
- Drink plenty of water
- Maintain a balanced diet
- Engage in moderate exercise
- Keep a regular sleep schedule
These aftercare steps help support the body’s natural metabolic process and improve overall body contouring results.
