Buying guide for Best cavitation machines

Even if you eat well and work out regularly, chances are there are still areas on your body with extra fat that you just can’t lose. Invasive procedures like liposuction can certainly help, but they’re just too extreme for some people. A cavitation machine can help you painlessly break down stubborn pockets of fat in your body for a more well-toned shape.

A cavitation machine uses high-frequency sound waves to heat and vibrate fat cells to disintegrate them. The lymphatic system then removes the fat from the body, so you wind up with a smoother, firmer figure almost immediately. You can use a cavitation machine on nearly any part of the body, including the belly, hips, thighs, back, upper arms, and chin. It can also help firm and tighten facial skin to improve the look of fine lines and enlarged pores.

Cavitation machines can be a pricey investment, though, so you want to choose an effective model that provides real results. Our buying guide gives you all the facts necessary to choose the best device for your needs. To make shopping even easier, check out our specific product picks.

When just starting out with a cavitation machine, it’s best to use the lowest setting. You can slowly increase the setting as you get accustomed to the heat and sensation.

Key considerations

Type

While all cavitation machines use high-frequency radio or sound waves to break down fat, you can choose from several different types.

3-in-1 cavitation machines feature a handheld instrument that helps break down fat and encourage fat drainage through the lymphatic system, a handheld instrument to boost skin firmness and elasticity, and a vacuum radio frequency (RF) instrument that can help treat cellulite.

4-in-1 cavitation machines offer all the same instruments as a 3-in-1 model and include a bipolar/tripolar RF instrument that can help tighten and treat facial wrinkles and lines.

5-in-1 cavitation machines are the most common type and feature all the instruments found on a 4-in-1 machine plus a small tripolar RF instrument to treat the skin on the face, including around the eyes.

7-in-1 cavitation machines offer all the same instruments found on a 5-in-1 model, but also feature a red light device to help smooth the skin.

Frequency range

For a cavitation machine to break up fat effectively, it must offer the right frequency range for its sound waves to vibrate and break up fat cells. If it doesn’t provide the right frequency, you won’t see the results you want from the machine.

The optimal frequency range for the process is 20 to 30 kilohertz. Cavitation machines that operate at a higher frequency range of 40 to 60 kilohertz aren’t effective because they’re too weak to penetrate and break down fat.

Heat regulation

The high-frequency sound waves used for the cavitation process generate heat. A cavitation machine should have an effective heat regulation system to help eliminate the excess heat so you don’t experience burns or other skin irritation. Heat regulation also protects the machine, enabling it to last longer.

Features

Gel vs. no gel

Most cavitation machines require you to use a lubricating gel or lotion to allow the instruments to move smoothly over the skin, though some models don’t need a gel for treatment. If you’d prefer a more convenient, easier-to-use machine, you may want to look for one that doesn’t require the use of a gel.

Size

Cavitation machines are available in a range of sizes. Some are extremely compact and feature a wand without a base. Small machines are easy to store, though they usually offer subtler results than larger machines.

Other machines have an extremely large base with a series of instruments or devices that you run over the body. Larger machines are typically more powerful and provide more dramatic results, but they require a lot more storage space. 

You can also find machines that fall somewhere in the middle of the size range. These have a separate base and instruments, but they’re easier to store than the large ones.

Settings

Intensity: Many cavitation machines offer multiple intensity levels, so you can adjust the setting based on the part of the body you’re treating.

Heat: You can usually choose from two or three heat settings.

Massage: Many machines have up to five different massage settings to target specific areas of the body based on how intense a treatment you require.

Screen

Some cavitation machines have a screen that displays all the machine’s settings, making it easy to check at a glance that the machine is set up correctly for the area of the body you’re treating. Some machines only have a small LCD screen, while others offer a larger, easy-to-read display. In general, the larger the machine, the larger its screen.

Treatment time

When choosing a cavitation machine, it’s important to think about how much time you have to devote to each treatment session. Some machines only require 10 minutes, while others require up to 30 minutes.

It’s also important to know how many times per week you can use the machine. Most cavitation machines suggest three sessions per week, but you can find some less powerful options that are suitable for daily use.

Noise

All cavitation machines make some noise, usually a low humming sound. However, if you’re sensitive to noise, you might want to choose a model designed to be quiet.

For best results, avoid drinking alcohol on the day before and after a cavitation treatment.

Cavitation machine prices

Cavitation machines vary in price based on the type, frequency range, size, and other features, but most cost from $18 to $799.

Inexpensive: The most affordable cavitation machines are the compact handheld machines that don’t necessarily operate at the optimal frequency to penetrate fat. These models are typically best for use on small areas of the body and face. You’ll generally pay between $18 and $132 for these machines.

Mid-range: These cavitation machines are typically 3-in-1 or 4-in-1 models. Some 5-in-1 or 7-in-1 models that don’t operate at the optimal frequency can also be found in this price range. You’ll usually spend between $132 and $380 for these machines.

Expensive: The most expensive cavitation machines are 5-in-1 or 7-in-1 machines. Most operate at the optimal frequency to provide effective results. These machines are often larger and less portable than cheaper models. You’ll typically pay between $380 and $799 for these machines.

Sitting in a sauna or steam room for 15 to 20 minutes after a cavitation machine session can help your lymphatic system get rid of fat more quickly.

Tips

  • Drink plenty of water before and after treatment sessions. This can make it easier for the lymphatic system to get rid of the fat after the sound waves have broken it down.
  • Exercise before and after treatment sessions. Exercise helps your lymphatic system remove the fat from the body.
  • Focus on one or two areas per session. The lymphatic system has to process all of the fat you break down to remove it from the body, so using the machine on too many areas at once can overload it.
  • Use the machine every few days. It’s usually best to do a session with your cavitation machine every two or three days to ensure you see the best results.

If you use gel with your cavitation machine, make sure it’s a water-based formula. That allows the gel to serve as a conductor, so the sound waves can better penetrate the fat you’re targeting.

FAQ

Q. Is it safe to use a cavitation machine?

A. A cavitation machine is usually perfectly safe to use. It’s equipped with safety features to ensure that the heat the machine generates won’t burn or otherwise harm the skin. However, if you have particular health issues or conditions, it’s a good idea to speak with your doctor before purchasing a machine to make sure that there are no risk factors that would make the treatments dangerous for you.

Q. Is using a cavitation machine painful?

A. There is no pain involved with using a cavitation machine. While it uses heat and sound waves to break down the fat in your body, you won’t feel any discomfort while using it. However, you should only use the machine for the recommended amount of time per session to avoid any issues.

Q. Where on the body can I use a cavitation machine?

A. You can use a cavitation machine on nearly any area of the body, including belly, thighs, hips, back, upper arms, jawline, and chin. Avoid using the machine around the eyes and heart.

Q. How long does it take to see results?

A. It depends on a variety of factors, including your body shape and the machine you’re using. Some users see results after two or three treatments, while others need about six sessions to notice a real difference. In general, you should typically see results within the first few months of use.
