Find the Right 6-in-1 Cavitation Machine for Your Practice

Ultrasonic cavitation is one of the most effective ways to reduce fat on targeted areas of the body, without requiring additional diet or exercise. The treatment works by sending low-frequency ultrasound waves into fat layers to destroy fat cells.

Rejuva Fresh's 6-in-1 cavitation machines are multifunctional systems that combine powerful ultrasonic cavitation with vacuum suction, radio frequency, and lipo laser.ย

What Makes a 6-in-1 Body Sculpting Machine Different?

A 6-in-1 body sculpting machine combines several distinct treatment technologies into a single system, rather than requiring separate equipment for each modality. This typically includes:ย 

  • An ultrasonic cavitation handle for fat reduction
  • A vacuum RF handle for lymphatic drainage and skin tightening
  • Multiple RF or lipo laser attachments sized for different treatment areas

For a spa or treatment center, this consolidation matters. Instead of purchasing and maintaining several single-function devices, your team works from one system that covers fat reduction, skin tightening, and cellulite reduction across both body and face.

The Mechanics Behind a Cavitation Machine 6-in-1 System

Ultrasonic cavitation works by sending targeted sound waves into fat tissue, causing bubbles to form around fat deposits. These bubbles make fat cell membranes rupture, converting the fat into glycerol and free fatty acids that the body eliminates naturally as waste.

For your practice, the more relevant question is how to pair frequency, session frequency, and complementary lymphatic drainage support to get the most consistent results for your clients. For a closer look at running a treatment session, see our guide on how to use a 6-in-1 cavitation machine.

Cavitation frequency and handle configuration vary quite a bit from one model to the next. See what sets each machine apart. Make sure to check each item for pricing and availability.

Machine Cavitation Frequency Best For
Erisยฎ Lipo Cavitation Machine 6-in-1 Professional Adjustable 10KHzโ€“100KHz, optimized at ~20KHz or 30KHz High-volume spas wanting adjustable frequency and multiple RF options for face and body
Heraโ„ข Multi-Wave Vacuum RF Cavitation Machine ~60KHz Practices wanting adjustable RF frequency (1MHz, 5MHz, 8MHz) alongside cavitation
2026 Adonisโ„ข II 30K Fat Blasting Cavitation Machine 6-in-1 ~30KHz Practices treating clients with higher body fat percentages who need deeper fat targeting
2026 Adonisโ„ข II 40K 6-in-1 Cavitation Machine for Fat Blasting ~40KHz Clients closer to their target weight who want more surface-level fat contouring
Adonisโ„ข 30K Fat Blasting Cavitation Machine 6-in-1 ~30KHz Practices wanting the standard 30KHz Adonisโ„ข system at a lower price point than the 2026 upgrade
SOLLIFTโ„ข Thermogenic Lipolysis Machine 6-in-1 ~65KHz Practices wanting the highest cavitation frequency in this lineup, paired with 950KHz RF
Adonisโ„ข 6-in-1 Cavitation Machine for Fat Blasting ~40KHz One of the best-selling cavitation machines in the beauty industry, helps get rid of stubborn fat and cellulite

Pair any of these machines with Perfection Body Gel or Sculpting Expert Body Gel, both conductive gels designed to improve energy transfer during cavitation, RF, and lipo laser treatments.

30KHz vs. 40KHz vs. 60-65KHz: Which Cavitation Frequency Is Better?

Frequency and wavelength have an inverse relationship in cavitation technology, meaning lower frequencies reach deeper into fat layers. Since most of Rejuva Fresh's 6-in-1 lineup runs on 30KHz, 40KHz, or 60-65KHz, here's how those three frequencies compare.

Frequency Depth Best Suited For
30KHz Deeper penetration Clients with higher body fat percentage, or thicker fat layers
40KHz Mid-depth penetration Versatile option effective across a range of body fat levels
60-65KHz Shallower, more surface-level penetration Clients closer to their goal weight, or general contouring and maintenance

There isnโ€™t a single frequency that is universally "better." The right choice depends on the client's body composition and treatment goal, which is why Rejuva Fresh offers multiple frequency options across this lineup.

What Clients Get From a 6-in-1 Body Contouring Machine

A 6-in-1 body contouring machine gives clients a non-invasive path to results they'd otherwise need to pursue through diet, exercise, or surgery alone. Common client-facing benefits include:

  • Visible fat reduction in stubborn areas like the abdomen, thighs, and back
  • Smoother-looking skin through reduced cellulite appearance
  • Skin tightening and improved elasticity from the RF component
  • Zero downtime, so clients can return to normal activity immediately after treatment

6-in-1 Cavitation Machine Use Cases for Spa and Clinic Owners

For a spa or treatment center, a 6-in-1 cavitation machine consolidates several revenue-generating services into one piece of equipment. This supports your business in a few concrete ways:

  • Reduces the number of individual machines you need to purchase, train on, and maintain.
  • Opens a body-contouring service line without requiring a separate RF or lipo-laser system.
  • Appeals to a broad client base, since the machine covers both face and body treatment areas.
  • Supports package-based pricing, since most protocols call for a multi-session treatment course rather than a single visit.

If you're weighing which machine fits your treatment menu and client base, contact us, and our team can help you decide.

How Many Inches Can You Lose With Cavitation?

Results vary by client, treatment area, and consistency of sessions, so there's no single guaranteed number. Cavitation is generally most effective when used as part of a full treatment course rather than a single session, and results tend to improve over multiple visits.

Frequently Asked Questions About 6-in-1 Cavitation Machines

Does a cavitation machine really work?

+

Yes. Ultrasonic cavitation uses sound waves to break down fat cell membranes, converting stored fat into substances the body eliminates naturally. Results are most visible when treatments are done consistently as part of a full course rather than a single session.

How do you use a 6-in-1 cavitation machine?

+

Each handle on a 6-in-1 cavitation machine serves a different function:

  • The cavitation head targets fat reduction.
  • The vacuum RF head supports lymphatic drainage and skin tightening.
  • Additional RF and lipo laser attachments allow for targeted treatment on smaller areas like the face.

Rejuva Fresh includes free training with every machine, so your team learns the correct technique for each handle.

Is 30K or 40K cavitation better?

+

Neither is universally better. 30KHz reaches deeper into fat layers, making it well suited for clients with higher body fat percentages, while 40KHz works more at the surface and suits clients closer to their goal weight. The right choice depends on the client being treated.

How many inches can you lose with cavitation?

+

Results vary by client and treatment area, and there's no fixed number that applies to everyone. Cavitation tends to work best as part of a multi-session treatment course, with results building over time rather than after a single visit.

What's included with a 6-in-1 cavitation machine from Rejuva Fresh?

+

Every purchase includes free personalized training, a lifetime warranty on the main machine, an 18-month warranty on parts, and ongoing customer support available 7 days a week.

What's the difference between the machines in Rejuva Fresh's 6-in-1 lineup?

+

The main difference is cavitation frequency and handle configuration. Machines range from 20KHz-adjustable systems like the Erisยฎ to fixed 30KHz, 40KHz, and 60-65KHz models, each suited to different body fat levels and treatment goals.

Can a 6-in-1 cavitation machine treat the face as well as the body?

+

Yes. Most machines in our lineup include dedicated RF handles sized specifically for facial and eye-area treatment, in addition to the larger handles used for body contouring.

What treatment areas can a 6-in-1 cavitation machine target?

+

A 6-in-1 cavitation machine is built to work across multiple areas of the body and face, thanks to its multiple handle attachments. Common treatment areas include:

  • Abdomen and waistline
  • Thighs and hips
  • Upper and lower back
  • Arms and underarms
  • Face and eye area, using smaller RF handles

The specific handles included vary by machine, so it's worth checking each model's included attachments if you're targeting a specific treatment area.
