High-Intensity Focused Ultrasound (HIFU) works by delivering precise ultrasound energy to the SMAS layer (3.0–4.5 mm) beneath the skin surface. The right energy level, cartridge depth, and pulse spacing are key for safe and visible lifting.
- Improves collagen stimulation for firmer skin
- Ensures patient comfort and consistent results
- Prevents overheating or burns during treatment
HIFU Energy & Depth Chart
Use this reference table to select the ideal cartridge and energy range for different zones.
| Cartridge | Depth | Area | Energy (J/cm²) | Spacing (mm) | Shots |
|---|---|---|---|---|---|
| 1.5 mm | Upper dermis | Forehead, under-eye | 0.10–0.30 | 1.0–1.2 | 100–150 |
| 3.0 mm | Lower dermis | Cheeks, jawline, neck | 0.30–0.60 | 1.2–1.5 | 200–250 |
| 4.5 mm | SMAS layer | Lower face, jowls, chin | 0.60–1.00 | 1.5–2.0 | 250–300 |
| 6.0–9.0 mm | Fat & fascia | Abdomen, arms, thighs | 1.00–1.50 | 2.0–3.0 | 400–500 |
Recommended Settings by Area
Jawline & Double Chin
Use 3.0 mm + 4.5 mm cartridges with 0.5–0.8 J/cm² energy and ~1.5 mm spacing. Double pass for stubborn sagging.
Neck Tightening
Use 3.0 mm at 0.4–0.6 J/cm². Avoid thyroid region; move slowly with continuous gel.
Forehead & Eye Area
Use 1.5 mm at 0.2–0.3 J/cm². One gentle pass only.
Common Mistakes & Safety Notes
- Too high energy in thin-skin zones
- Overlapping more than 30 %
- Dry cartridge or insufficient gel contact
Troubleshooting “No Energy Output”
- Re-insert cartridge until it clicks firmly.
- Clean handle pins with alcohol swab.
- Perform test shot with gel at lowest setting.
- Try a new cartridge if issue persists.
- Reboot and run self-diagnostic (engineering mode).
- Check power supply — always use OEM adapter.
| Symptom | Cause | Fix |
|---|---|---|
| No energy firing | Cartridge not locked / board fault | Reseat cartridge, run self-test |
| Handle warm, no pulse | Crystal damage | Send handle for calibration |
| Energy fluctuation | Loose connector | Clean pins or replace cartridge |
| Error E3/E4 | Firmware issue | Restart & contact service |
FAQs
Best HIFU Energy for Jawline Lift
Begin with 0.5 J/cm² on 3.0 mm; increase to 0.8 J/cm² if tolerated. Follow with 4.5 mm pass.
HIFU for Double Chin
