Usage Guide
Tip: Apply a generous layer of essential oil or massage gel to the treatment area before use. We recommend drinking a glass of warm water before each session to support healthy circulation.
🔵 Abdomen
Treat the abdominal area for 30–45 minutes per session. Use circular motions or linear strokes moving from the sides of the waist toward the navel, finishing with clockwise circles around the navel area.
🔵 Thighs
Treat each thigh for 20–30 minutes. Move in circular motions from the outer to inner thigh, then slide and lift from above the knee toward the upper thigh.
🔵 Arms
Treat each arm for 15–20 minutes. Move from the outer to inner side of the arm, lifting upward from bottom to top. Focus on areas of excess softness such as the upper arm.
Important Precautions
- Always use a massage medium (essential oil recommended); avoid pasty or thick substances.
- The device auto-shuts off after approximately 30 minutes — simply restart to continue your session.
- After each session, use gentle massage strokes toward nearby lymph nodes to support natural toxin metabolism.
- For best results, drink warm water before treatments to support skin blood circulation.
- Not suitable for use over bony areas, open skin, or near electronic implants. Consult a healthcare professional if unsure.

Frequently Asked Questions
Q: How does the 40K ultrasonic cavitation body massager work?
A: The device emits 40,000 Hz ultrasonic sound waves that penetrate the skin's surface layers. These waves create micro-vibrations that stimulate the tissue, promote circulation, and deliver a deep massage effect to areas like the abdomen, thighs, and arms — helping to smooth skin texture and support your contouring routine.
Q: How long should each treatment session last?
A: Treatment times vary by area. The abdomen typically takes 30–45 minutes, thighs 20–30 minutes per side, and arms 15–20 minutes per side. The device features an automatic 30-minute shut-off; simply restart it if your session requires more time.
Q: What medium should I use with this ultrasonic body massager?
A: The manufacturer recommends using essential oil or a water-based massage gel as the conductive medium. Avoid thick, pasty substances. Using a suitable medium ensures optimal contact between the treatment head and skin for the best results.

A: Yes. The Vilnason H-038 is CE, FCC, and RoHS certified, meeting international safety and environmental standards. It features a built-in 30-minute auto shut-off for safe home use. Avoid use on bony prominences, broken skin, and near any implanted medical devices. Consult your healthcare professional if you have any concerns before use.
Q: Is the device compatible with international power outlets?
A: Yes. The device supports a universal input voltage of 100–240V AC, making it compatible with power outlets in most countries around the world (note: an appropriate plug adapter may be required depending on your region).
