Learn the step-by-step process for using a 3D S shape machine with 3D cavitation and RF lipo to achieve salon-quality body contouring results at home.

Quick answer

To use a 3D S shape machine for body contouring, start with clean, dry skin, apply a conductive gel, and follow a pattern of 3D cavitation followed by RF lipo on each target area, respecting the recommended treatment time and intensity settings.

Why combine 3D cavitation and RF lipo?

3D cavitation uses low-frequency ultrasound waves to disrupt fat cells, while RF (radio frequency) lipo heats the deeper skin layers to stimulate collagen production and tighten the skin. Using both on the same session (starting with cavitation) addresses both fat reduction and skin laxity, giving a more balanced contouring result. Many users see better outcomes than with either technology alone.

Key safety and preparation tips

Always start with clean, dry skin free of lotions or oils. Apply a generous layer of conductive gel to the treatment area and the machine's handpiece to ensure smooth gliding and prevent overheating. Never treat the same spot for more than the recommended time (usually 5–10 minutes per area, depending on the machine's manual). Avoid bony areas, the neck, eyes, and any implanted medical devices.

Hydrate well before and after the session, and avoid alcohol or caffeine on treatment days. If you feel sharp pain or excessive heat, stop immediately and lower the intensity.

Step-by-step guide to using a 3D S shape machine

Step 1: Prepare your skin and the machine: Clean the target area thoroughly and pat dry. Apply a thick layer of conductive gel to both the skin and the 3D cavitation handpiece. Plug in the machine and set the cavitation mode to a low intensity (level 1–2) for your first session. Common mistake: using too little gel can cause the handpiece to drag and overheat the skin. Reapply gel if it dries out during the session.
Step 2: Perform 3D cavitation on the target area: Starting from the outer edge of the area (e.g., abdomen or thighs), move the handpiece in slow, circular motions. Keep it in constant contact with the skin. Treat each spot for about 3–5 minutes, then move to the next adjacent area. Do not hold the handpiece still. Checkpoint: you should feel a gentle vibration and warmth, not sharp pain. If you feel discomfort, reduce the intensity or stop.
Step 3: Switch to RF lipo mode: After completing cavitation on all target areas, switch the machine to RF lipo mode. Set the intensity to a comfortable warmth (level 2–3 for beginners). Glide the RF handpiece over the same areas using slow, overlapping strokes for 5–10 minutes per area. Common mistake: rushing the RF step or using too high an intensity can cause burns. Always test on a small patch first.
Step 4: Clean up and post-treatment care: Wipe off any remaining gel from your skin and the handpieces. Drink a glass of water to help flush out released fat metabolites. Avoid eating a heavy meal for at least 1 hour after the session. For best results, repeat the process every 2–3 days for 4–6 weeks, then switch to maintenance sessions once per week.
