SONO Prep — 5 Minutes First

Run Sequence 1 (Lymph Drainage) for 5 minutes, with extra time on Node 3 (45 seconds instead of 30). Node 3 at the ear/jaw junction is the primary lymphatic exit for the lower face tissue you are about to treat.

Use slow circular passes across the jowl and lower cheek during prep to warm the SMAS tissue before HIFU.

Switch to HIFU — 4.5mm Mode

Swap to the HIFU cartridge. Select 4.5mm mode (SMAS layer) to lead the session.

Energy Level: Level 2 for sessions 1–2. Level 3 for sessions 3–4. Level 4–5 from session 5 onward. Never jump levels within a single session.

Pre-Jowl Sulcus First

Slow circular passes over the pre-jowl sulcus — the hollow directly beside the chin. 60–90 seconds per side.

Treating this hollow first softens the visual boundary before lifting the jowl tissue above it.

Jowl Zone — Upward Strokes

Slow upward-angled strokes from the jowl tissue toward the cheekbone. Use deliberate, directional pressure.

2–3 minutes per side.

Jawline Definition

Short linear strokes along the mandible from chin to ear, following the bone line precisely.

90 seconds per side.

Dual Mode Finish Pass

Switch to Dual Mode (3.0mm + 4.5mm). One full, slow pass over the entire lower face to seal the session.

Post-Treatment

Final drainage sweep: Node 3 → 2 → 1. Apply peptide or EGF serum immediately.

Do not perform facial massage or manipulation for 24 hours after HIFU treatment.
