Cavitation uses ultrasound energy to target fatty areas warm, while cryolipolysis (fat freezing) uses controlled cooling. Both are non-invasive body contouring treatments salons offer in courses, and neither is “better” outright — the right choice depends on your clients, your space and how you plan to fill the diary. Results vary from person to person.
If you’re weighing up a body line, this is the comparison owners actually ask for: not the science lecture, but which machine fits your salon and why. We’ve run salons ourselves, so we’ll give you the honest trade-offs.
What’s the difference between cavitation and cryolipolysis?

Both are cosmetic body-contouring treatments — not medical procedures, and not weight-loss treatments — but they work in opposite ways:
- Cavitation applies low-frequency ultrasound to targeted areas during a comfortable, warm session. Clients usually book a course of sessions.
- Cryolipolysis applies controlled cooling to a pinch of tissue held by an applicator, over a longer single session, typically with fewer sessions per area.
That difference in mechanism changes the client experience, the session length and how you’d package and price each one. It doesn’t make one superior — it makes them suited to different salons and different clients.
Cavitation vs cryolipolysis: the decision table

Use this as a starting point, then talk it through against your own client base. (General guidance — confirm specifics against the product data on file.)
| Consideration | Cavitation | Cryolipolysis (fat freezing) |
|---|---|---|
| How it works | Ultrasound energy, targeted, warm | Controlled cooling of a held area |
| Typical session | Shorter, comfortable | Longer, one applicator area at a time |
| Course pattern | Often a course of several sessions | Fewer sessions per area |
| Client comfort | Warm, relaxing | Cold, pulling sensation at the start |
| Areas | Flexible across body areas | Suits pinchable areas |
| Throughput | Faster sessions, more bookings/day | Longer sessions, higher per-session price |
| Search demand (UK, Semrush, Jul 2026) | cavitation machine 1,000/mo | cryolipolysis machine 170/mo |
| Best when | You want flexible, course-based body work | You want a premium, fewer-visit body line |
Search demand isn’t everything, but it’s a fair signal that cavitation is the more-searched body line of the two in the UK right now — worth knowing when you think about how clients will find the service.
Which is easier to sell and fit into a salon?

Two practical points decide this more than the technology:
Throughput. Cavitation sessions tend to be shorter, so you can book more per day. Cryolipolysis sessions are longer but command a higher price per session. Neither is automatically more profitable — it depends on your opening hours, your pricing and how busy you keep the machine. A machine only pays when it’s booked.
Client expectation. Both are gradual, course-based treatments where results vary. Your job is to sell a realistic course and manage expectations honestly — which, done well, protects your reviews and your repeat bookings. Over-promising is the fastest way to lose both.
If pricing and packaging body courses is the part you’re unsure about, that’s exactly what the 1:1 coaching in the Contour package is for.
Do I need one, the other, or both?

Plenty of salons run both, because they answer slightly different client wants — flexible, warm, course-based work versus a premium, fewer-visit option. If you’re adding your first body line, though, start with the one that fits your clients and your budget, get it busy, and add the second later once it’s earning.
Both cavitation and cryolipolysis are green-tier, salon-legal lines under the direction England’s licensing regime is heading — treatments a salon can offer without moving into clinic-only territory. That’s worth confirming as the rules firm up; our licensing guide covers where each treatment sits, and it’s evolving through 2026–27.
What comes with a Contour body machine?

Whichever route you choose, every Contour machine comes with the complete package:
- The machine — matched to your client base.
- Free accredited qualification — VTCT training, delivered by SKIN13.
- Free manufacturer training — for up to five staff.

- FCA-regulated finance — spread the cost. Finance is subject to status and affordability.
- After-sale support — from a team that’s run salons themselves.
Talk it through before you commit

The best way to choose is a proper conversation about your clients and your space — not a spec comparison alone. Explore the cavitation machine and the cryolipolysis machine, then book a demo and we’ll help you work out which body line fits first. And if you want the wider picture, start with our guide to choosing an aesthetic machine.
