Jess love handles before and after

★★★★★
Love handles finally going down!
"OK so I've been using this thing for about 5 weeks now and I can't believe how much my love handles have shrunk. I do cavitation on each side for like 15 min then follow up with RF. My jeans fit so much better and I actually feel confident in a crop top again. Best purchase I've made in a long time honestly."

★★★★★
My belly looks so much smoother now
"After having two kids, my stomach just never bounced back. The skin was loose and the stretch marks were really visible. I've been doing treatments 3x a week for about a month, focusing on cavitation first then the RF head. The skin is noticeably tighter and the texture has improved so much. I wish I started sooner!"

★★★★★
Double chin is almost gone!
"I was so self conscious about my chin in photos. I used the small RF head under my jawline about 3 times a week, just 10 minutes each time. By week 3 I could already see it tightening up. Now at 6 weeks the difference is crazy. My friends keep asking what I did lol."

Cellulite on my legs is fading
"The back of my thighs had the worst cellulite and I'd tried everything. Creams, dry brushing, you name it. This machine actually made a visible difference. I use the cavitation head first, then the vacuum RF to really work into those dimply areas. After about a month my legs look so much smoother. I'm not hiding them anymore."

Skin looks years younger
"I bought this mainly for body contouring but decided to try the tripolar head on my face too. I'm 52 and honestly the fine lines around my eyes and mouth have softened quite a bit. It feels like a warm facial massage. Very gentle. I do it twice a week and my skin has this glow to it now that I haven't had in years."

Tummy is getting flatter every week
"I started using this about 6 weeks ago on my lower belly. That area has always been stubborn for me no matter how much I work out. The combination of cavitation and then RF afterwards has really helped tighten everything up. I can see my stomach getting flatter and the skin isn't as saggy. Really impressed with this little machine."

Finally comfortable in shorts again
"I've had cellulite on my legs since my twenties and it only got worse with age. A friend recommended this and I figured why not. I do sessions while watching Netflix, mostly on the back of my thighs and butt. The vacuum head is my favorite part, it really works the skin. After about 5 weeks I can genuinely see the difference. So happy."

★★★★★
Arms look way more toned
"The loose skin on my upper arms always bothered me, especially in sleeveless tops. I use the RF head on both arms about 3 times a week. It's only been a month but the skin already feels tighter when I touch it and the wobble is definitely less. Quick sessions, easy to do, and it actually works. What more could you ask for?"

What Is Ultrasonic Cavitation?

The same core body-contouring technology used in salons — low-frequency 40K ultrasound — in a handheld machine you use at home.

Harness the power of high-frequency sound waves to break down stubborn fat at home:

✓Creates micro-bubbles that target stubborn fat areas
✓Bubbles expand and collapse, breaking down fat cell walls
✓Releases the fat content without harming surrounding tissue
✓Your body naturally flushes away the released fat

The result? A visibly slimmer, more contoured shape — no needles, no downtime, on your own schedule.

Ultrasonic Cavitation FAQ

How does ultrasonic cavitation work?
Ultrasonic cavitation uses low-frequency (40K) sound waves applied to the skin with a handheld probe. The ultrasound creates pressure waves designed to target stubborn fat areas, while the body's natural processes do the rest. It's the same core technology used in professional body-contouring studios — our machines bring it home in a non-invasive, no-downtime format. Most machines pair it with radio frequency (RF), which uses gentle heat to support skin firmness.
Is it safe? Does it hurt?
Cavitation and RF are non-invasive — no needles, no surgery, no recovery time. Most users describe the sensation as a warm massage with a faint humming from the probe. As with any wellness device, it isn't for everyone: we don't recommend use during pregnancy, with a pacemaker or metal implants, or over broken skin. When in doubt, check with your doctor first — and always follow the included usage guide.
How often should I use it, and when will I see results?
Most users incorporate 2–3 sessions per week per body area, keeping each session within the recommended time in the user guide. Consistency matters more than intensity. Results vary from person to person and depend on factors like diet, hydration, and activity — cavitation works best as part of a healthy routine, not as a replacement for one.
Which machine should I choose?
Short version: the 3-in-1 is the focused starter, the 4-in-1 adds vacuum RF sculpting at the best price-to-features ratio, the 6-in-1 adds lipo laser pads for a full home-studio kit, and the 9-in-1 includes everything plus the spa extras (EMS pads, cold hammer, and BIO microcurrent light therapy). The comparison above this section breaks it down feature by feature.
How does this compare to salon treatments?
Professional body-contouring sessions commonly run $150–300+ per visit, and most studios recommend a series of sessions. Our machines use the same underlying 40K cavitation + RF technology in a home format — a one-time purchase you can use on your own schedule, as often as your routine calls for.
What about shipping, warranty, and returns?
Every machine ships free and fast from our US warehouse. All machines are covered by our warranty, and our support team actually answers. Full details are in our shipping policy and returns policy.
Clinical studies
Independent peer-reviewed research has explored cavitation and radio-frequency body-contouring technologies. A couple of references for further reading: Individual results vary. These studies are provided for educational reference and do not represent a guarantee of specific outcomes.
