Melt Stubborn Fat & Reshape Your Silhouette — 40K Cavitation at Home
Break down stubborn fat, smooth cellulite and tighten skin with SaintQueen’s 40K ultrasonic cavitation machines. Using 40,000Hz low-frequency sound waves — the same non-invasive body contouring technology found in aesthetic clinics — these devices target fat cells in the waist, abdomen, thighs, hips and arms while tripolar and multi-polar RF handpieces lift and firm skin from face to body.
With models from $159.99 to $799.99, there’s a 40K cavitation system for every goal: compact 3–4 in 1 machines for at-home body sculpting, and full 6 in 1 salon-grade stations with vacuum massage, EMS laser pads and multi-pole RF for complete face and body treatments.
Technologies that deliver real results
40K Ultrasonic Cavitation
40,000Hz sound waves penetrate the fat layer to break down fat cells and support lymphatic detox — no surgery, no downtime.
Multi-Polar RF Firming
Tripolar RF lifts delicate face and eye zones; 6-pole RF tightens waist, thighs, arms and calves for visibly smoother skin.
Vacuum Lymphatic Massage
Negative-pressure massage boosts circulation and lymph drainage, reducing fluid retention and improving body contour.
Face & Body in One
Interchangeable probes handle facial lifting, eye care and full-body sculpting — one machine replaces a whole cabinet of devices.
How to choose the right machine
First-time home use — the SQ16 Basic or SQ169 Basic 3 in 1 ($159.99) pairs 40K cavitation with tripolar and 6-pole RF for core fat-blasting and skin tightening.
Fuller home routines — step up to a 4 in 1 with vacuum massage (SQ169 Basic $189.99, SQ16B Basic $199.99) to add lymphatic drainage and body maintenance.
Serious sculpting or small salon — the SQ47B Pro 6 in 1 ($799.99) adds EMS laser pads and multi-pole RF for clinic-grade fat dissolving, cellulite removal and face firming.
40K vs 80K? — 40K waves are gentler and cover larger areas comfortably, ideal for beginners and sensitive zones; 80K penetrates deeper for stubborn fat and faster results. Both are non-invasive.
