Quick Summary

What Is An Ultrasonic Cavitation Machine?

Ultrasonic cavitation machine is a localized fat-burning machine used for cosmetic and beautifying procedures to get rid of fat from problem areas like belly, waist, thighs, glutes, upper arm, and face.

These machines are a non-invasive and pain-free alternative to liposuction. They use high-frequency heat and sound waves that penetrate your skin to break down the fat cells. The liquefied fat cells are then excreted naturally by the liver through the lymphatic system. Small and portable ultrasonic cavitation machines can be used at home to get a toned and sculpted body.

How Does It Work?

An ultrasonic cavitation machine works by heating up the subcutaneous layer of fat. These are the fat cells that are found underneath the surface of your skin. Here’s an easy way to understand how this machine works:

  • When the machine is rubbed on your skin, a frequency of 40 kHz or 5 MHz is used to cause vibrations in the fat cells.
  • The ultrasonic waves heat up the fat cells, causing tiny air bubbles or cavities to form between them.
  • These air bubbles break down the fat cells due to the pressure created.
  • The pressure ends up bursting and liquifying these fat cells, thereby releasing the contents of the cells into the body.
  • These unwanted fat contents are removed through the lymphatic system.

A short treatment of 30-45 minutes is applied to the waist or thighs.

Ideally, most patients require 10-12 treatments, and many see up to 2 inches of surface reduction only after 5 treatments. But you need to understand that each body is different, and the results vary accordingly.

The ultrasonic cavitation machineis an impressive breakthrough in the non-surgical fat loss technology. Here’s a list of the benefits of cavitation machines and why many people find them helpful.

Benefits Of Cavitation Machines

  • Good For Spot Reduction And Full Body Reduction

Cavitation machines can be used on any area of your body where there is extra fat – the thighs, belly, back, legs, arms, shoulders, neck, or buttocks. They can also be used on smaller areas like the chin and the area around the eyes.

  • No Post-Surgical Scars (Non-Invasive)

Unlike surgical procedures like liposuction, cavitation machines do not involve any invasive techniques. There are absolutely no bandages, anesthesia, or blood involved. It is one of the safest weight loss treatments out there.

  • Chemical-Free Technique

A cavitation machine uses ultrasonic waves that break down the fat cells into liquid. Once the fat cells are liquefied, they are eliminated from your system through lymphatic drainage.

  • Painless Cosmetic Procedure

You will not experience any pain or discomfort during and after the procedure. You may feel a gentle warming sensation on your skin.

  • Quick And Short Procedure

Body sculpting through cavitation machines is a quick procedure. Each therapy session may take 30-60 minutes or less, depending on the instructions provided by the company selling the machine.

  • Effective And Fast Results

The results are often visible right away. Some people may notice changes within the first treatment. But generally, the results are noticed in as little as three days or after 2-3 sessions. Depending on your body type, you may need at least 6-12 sessions to get your desired results.

  • Easy Procedure

Cavitation therapy is a simple procedure. All you have to do is massage the problem area with the device for 10-20 minutes for 10-12 sessions. It offers a solution that works on most body types and involves minimal effort. Of course, along with this, you need to follow a healthy diet, increase your water intake, and maintain a moderate exercise regimen.

Before you purchase a cavitation machine, there are some basic features that you need to consider:

  1. Type – EMS, infrared, ultrasonic, RF
  2. Intensity levels
  3. Heat regulation

Before And After Results

Before And After Results

After a few uses, you can start seeing visible results. But, it will differ from person to person and also depend on how you maintain the fat loss. Here are a few solid tips on how to main weight loss after going through non-invasive weight loss treatment.

How To Maintain Weight Loss After Cavitation Treatment

  • Drink at least 8 glasses or 3-4 liters of water every day.
  • Avoid alcohol, coffee and tea with sugar and milk, aerated beverages, packaged food, and processed food.
  • Stick to a healthy low-carb diet.
  • Practice intermittent fasting to keep your body healthy.
  • Exercise 5 hours a week – 3 days cardio and 2 days strength training.
  • Do not compromise on sleep. Get at least 6-7 hours of sleep.

It is clear that ultrasonic cavitation machines are effective and this weight loss can be maintained. But before you make your purchase, here are some things that you need to consider.

Things To Consider Before Buying A Cavitation Machine

  • Features

Some expensive machines come with Quadrupolar 3D RF, color LEDs, TENS/EMS massager, gloves, facial and eye probes, and other special attachments. Though not all machines come with these tools, ensure you buy one that has the features that you need or suits your body type.

  • Treatment Duration

While some ultrasonic cavitation devices take 30 minutes per session, some may only take 15 minutes. Also, you need to know the usage limit per week and day. Most cavitation machines are designed to be used thrice a week, but there are some that can be used every day.

  • Size

Cavitation machines come in different sizes. There are tiny and portable devices, medium-sized 4-in-1 cavitation machines, and big or complex models. The bigger the device, the higher the price. Choose a device that aligns with your ultimate goals. If you are someone who travels regularly, select a single-probe (head) cavitation machine.

  • RF

This is the most important feature to look for in a cavitation machine. The greater the RF, the higher the intensity of the treatment. Usually, 7-in-1 complex cavitation machines have higher RF than portable ones. Those seeking quick results can use devices with high RF. It helps tone your body, slim down fat areas, and sculpt extra inches in just a few sittings. Those seeking slight changes in their body can opt for low RF machines.

  • Intensity Levels

Most cavitation machines come with multiple settings for different areas of the body. For example, some machines include 5 massage nodes for tapping, kneading, massaging, and slimming. The EMS function allows you to choose from five levels of intensity and two levels of ultrasonic intensity.

  • Safety

Although cavitation machines are perfectly safe, it’s important to double-check the safety features of the machine before buying it. Heat regulation and auto shut-off timer are two important things to check for in a cavitation machine. The good news is that unlike other fat removal methods, this procedure does not involve pain, scarring, or bleeding. It is a 100% non-invasive procedure with no downtime. However, it is always safe to purchase a machine from a reliable brand that offers decent and premium-quality features.

  • Heat Regulation

An efficient heat regulation system that disperses excess heat is mandatory to prevent skin burns and inflammation.

  • Gel

Most cavitation machines are used with an ultrasound gel. This is to operate the device smoothly over the skin. Ensure to check if the machine you are looking for requires an ultrasound gel.

  • Detailed User Manual

Most cavitation machines are equipped with complex buttons and settings that require precise knowledge to operate. If you don’t have a detailed instruction manual, using the probes in the right manner can be challenging. It is important to be aware of all the functions to maximize the device’s efficiency.

  • Warranty

When a brand offers a warranty, buying the product will give you peace of mind and assurance that the machine will last longer. During this period, you can replace defective parts or service the machine to increase its efficiency. Most branded cavitation machines offer a favorable warranty.

  • Price

Most cavitation machines that have special features, extra tools, and high-quality material cost a bomb. Therefore, consider your budget and evaluate your needs before buying the device.

While scrolling through different cavitation machines, you must have come across ‘RF,’ ‘3-in-1,’ or ‘7-in-1’ units. These are nothing but different types of cavitation machines that serve different purposes. Let’s look at them.

Types Of Cavitation Machines

1. Ultrasonic Cavitation Machine

Ultrasonic cavitation machines are the most popular cavitation machines. High Intensity Focused Ultrasound (HIFU) machines use 2-7.5 MHz pulse of vibrations for a designated time through a stainless steel probe head. It heats up the focused area to spot-reduce fat. These machines usually have two levels – low for sensitive skin, and high for areas with thicker skin(4), (5).

2. Radio Frequency Device (RF)

Radio Frequency (RF) cavitation devices emit radio frequencies of 3-24 GHz (6). The RF radiation heats the collagen-rich layers of your skin, called the ‘dermis.’ This helps tighten the skin, regenerate collagen, and reduce cellulite and wrinkles. Radio frequency cavitation machines help improve the texture and appearance of your skin. There are various types of RF cavitation devices:

  • Bipolar RF devices are used for facelifting, which can reduce saggy skin and wrinkles.
  • Tripolar RF devices are for treating the delicate skin around the eyes.
  • Hexapolar RF devices are meant for treating thicker skin and removing cellulite.

3. Infrared (IR) Light

Some cavitation machines use infrared light that penetrates the skin and generates heat. This preps the skin for better and deeper penetration of the radiofrequency energy in the targeted tissue (7). It increases blood circulation and helps your body recover and heal quickly after an injury.

4. EMS

EMS is an Electronic Muscle Stimulator that produces low-frequency electrical impulses through electrode pads, which cause the muscles to contract. This way, your muscles exert more than 4000 joules per second.

The muscle contraction can be frequent or can help for several seconds. This deep and intense muscle contraction helps massage the muscles, thereby helping to make the body look more toned and sculpted.

Now, let’s answer the question that is on everyone’s mind.

How Safe Are Ultrasonic Cavitation Machines?

Although ultrasonic cavitation is a pain-free, non-invasive, and non-surgical procedure, there isa slight chance of skin burns if the treatment is done for more than 10-20 minutes per session. During the treatment, you will feel some warmth due to the high-frequency heat waves. This may last until a day. To prevent redness and burns, you must check the user manual and stick to the time mentioned in the manual.

For people with liver issues, this process may not be 100% successful as this organ needs to function well to lose the decomposed fat.

Check out the next section to find who should and should not use an ultrasonic cavitation machine.

Who May Use A Cavitation Machine

Cavitation machines are ideal for healthy individuals who want to lose anywhere between 5-100 pounds. They are not effective for reducing obesity. These devices are mainly used for getting rid of the last-standing stubborn fat and for shaping the thighs, legs, waist, upper arms, and belly. Cavitation machines are a good choice for people who want to tone certain areas of fatty deposits but do not want to undergo any surgical treatment like liposuction.

Who Should Not Use A Cavitation Machine

The following people should not use a cavitation machine:

  • Minors
  • Pregnant and breastfeeding women.
  • Menstruating women.
  • People with cardiac diseases, hypertension, diabetes, skin cancer, fatty liver, epilepsy, and malignant tumor.
  • People with photosensitive skin.
  • People with skin infection, burnt skin, skin allergies, and anticoagulant disorder.
  • People with surgical scars.
  • People with cancer and weak immunity.
  • People with metallic implants.


Cavitation therapy is not a weight-loss treatment. It is not designed to fight weight gain or obesity. These machines are very expensive, and some patients may not gain any noticeable results.

Here are some tips that you can follow for maximum results.

Tips To Follow While Using A Cavitation Machine

  • Go through the manual and read the instructions thoroughly before you begin.
  • Consult a doctor if you have any chronic or skin disease.
  • This process is a complete no-no for pregnant women.
  • Always use a cavitation gel when using this device to avoid burns.
  • Take inches as a unit of mass.


Cavitation machines are easy-to-use devices for spot fat reduction that you can use at home. They cost less than the medical spa treatments for body sculpting. You can see results in 10-12 sessions. If you want to rejuvenate the appearance of your skin and get rid of stubborn fat from a problem area, a cavitation machine can be a good bet. However, you must maintain a healthy diet and work out regularly for maximum effects.

Frequently Asked Questions

How long does it take to see results from ultrasonic cavitation?

Generally, most clients start to see a difference in 3 treatments. Often, you’ll see results after the first session itself. However, between 8 and 12 sessions are needed for optimum results.

Is cavitation an FDA-approved treatment?

Yes, ultrasound cavitation + RF for body sculpting is an FDA-approved treatment.

What are the other names of ultrasonic cavitation?

Ultrasonic cavitation is also known as ultrasound cavitation, cavitation,  ultra cavitation, body contouring, body sculpting, and Ultra Shape.

Can I lose weight with ultrasonic cavitation?

Ultrasonic cavitation is a procedure to eliminate localized fat. The localized fat tissue in the belly, waist, chin, upper arms, thighs, and buttocks becomes resistant to exercise and diet. Ultrasonic cavitation procedure can help get rid of these localized fat stores. However, it is NOT a weight loss treatment neither will it treat obesity and related comorbidities.

What is the after-care for ultrasonic cavitation?

  • Increase water intake.
  • Choose healthier and nutrient-rich foods.
  • Exercise daily to tighten the skin and lose any extra weight.
  • Avoid fatty foods.
  • Avoid alcohol.

Will I put the weight back on?

If you do not maintain a healthy lifestyle, eat healthy food, and exercise regularly, you will put the weight back on. The removal of the liquid content consisting of fatty acids and glycerol allows fat cells to decrease in size. However, excessive calorie intake could cause the cells to increase in size once again. It is, therefore, important to maintain a healthy lifestyle with a well-balanced diet.

Are there any side effects?

Cavitation machines are mostly safe and have minimum side effects. If you have photosensitive skin, it is best to get the treatment for a short duration. Never exceed the massage time as directed on the manual to prevent redness and burning.

How often can I use my cavitation machine?

Most clients require 5-6 sessions to get the desired results. Remember that there should be a gap of three days between each session.

Will the cavitation machine treat cellulite?

The infrared light mode in a cavitation machine is built to help reduce cellulite. However, it may not eliminate cellulite completely. With regular use, your skin tone may brighten and even out but you must also massage oil in the affected area, eat healthy food, and work out regularly to see long-lasting results.

How long do ultrasonic cavitation results last?

Ultrasonic cavitation does not completely destroy fat cells. It just empties the content inside these cells. Hence, there are high chances of regaining the fat again. Therefore, to maintain the results, you need to follow a balanced diet.

What is the difference between a cavitation machine and laser liposuction?
