Does Ultrasonic Cavitation Really Work? Review & Before/After

Lose weight in the right places and visibly tighten your body without heavy training or surgery? Ultrasonic cavitation has such features. But is everything as they say? We look into this question based on scientific research.

Losing weight is more than a goal these days, it has become a way of life. Many patients demand new ways to lose fat when diet and exercise are not working. This is why finding the right services that can help you may be challenging.

One of the treatments is ultrasonic cavitation. This is a non-invasive, painless method of losing weight, the results of which are visible already after the first procedures.

In this article, we will look at this method of losing weight, how it works, its effectiveness based on scientific research, as well as recommendations for preparing for the procedure.

What is ultrasonic cavitation treatment?

Ultrasonic cavitation, also called ultrasonic lipolysis, is a weight loss procedure that uses low-frequency sound waves to break down fat cells, resulting in inches loss in the treated areas and a slimmer figure.

The science behind this process is called “cavitation” and allows for a non-invasive procedure to be performed without causing any damage or pain, without surgery or recovery time. It takes just minutes per area, with each session leading to inch loss as well as fat loss in targeted areas such as the abdomen, waist, hips, or thighs. The procedure is completely safe to perform and no anesthesia is required.

Targeted areas for ultrasonic cavitation

Ultrasonic cavitation works best on parts with localized fat.

Such areas include:

  • Abdomen, but it should be remembered that you should not work its lower part, where the reproductive organs are located;
  • Sides and lower part of the back — makes the waist appear narrower;
  • Thighs, eliminating fat deposits, making legs slimmer, and smoothing cellulite;
  • Arms, tightening the flabby skin on the inside of the shoulders;
  • Buttocks, making them firmer.

This procedure should not be performed on parts of the body such as the head, neck, or other bony areas of the body. The reason for this is to avoid negative consequences (such as the development of cardiovascular diseases, impaired blood circulation) and painful sensations.

How does ultrasonic cavitation work?

Cavitation is a liposuction technique that does not require the use of needles, anesthetic, or prolonged downtime.

Cavitation destroys fat cells using low-frequency sound waves that penetrate and cause them to seep into the lymphatic system.

Once such a cell is destroyed, the fat is released between them, where they are converted into protein and then into free fatty acids and glycerol. Free fatty acids are transported to the liver, where they are removed from the body, and glycerin is used as energy.

To accelerate this process and enhance the effect, it is recommended to combine ultrasonic cavitation with pressotherapy or lymphatic drainage massage — manual or hardware.

Also, do some exercise after the treatment, as this helps to use some of the energy released during the treatment.

The effectiveness of ultrasonic cavitation in weight loss based on clinical trials

The risks associated with currently available invasive body contouring procedures motivate the need for safer, non-invasive technologies to improve the appearance of body contour. One of the popular treatments is ultrasound cavitation.

Below are the results of studies of this method of losing weight.

The study [1] was involving 164 people. They received one treatment with a radiofrequency device in the abdomen, thighs, or flanks and were evaluated over 12 weeks. As a result, this treatment was safe and well-tolerated. It reduced the circumference of the treated area by about 2 cm. Most of the effect was achieved within 2 weeks and persisted after 12 weeks. Adverse events (redness, pain) were reported, all of which were expected, moderate, and resolved during the study period.

The following study [2] was performed on 30 patients. All of them underwent three courses of treatment with an interval of 1 month. The areas to be treated included the abdomen, thighs, flanks, inner knees, and chest (for men only). The result showed that all patients showed a significant decrease in the thickness of the subcutaneous fat tissue in the treated area. The average decrease in the thickness of belly fat after three procedures was 2.28 cm. The hip circumference decreased by an average of 3.95 cm, which has rather good results.

For the following study [3], 14 women were selected who were treated every two weeks with an ultrasound device on one hip and the other hip served as an internal control. After treatment, patients were followed up at 4, 8, and 16 weeks. The results showed that there was a significant 22.20% (4.17 cm) decrease in belly fat thickness at 16 weeks. The decrease in thigh fat thickness was 19.23% (4.03 cm). No adverse side effects other than mild erythema were reported.

This study [4] aims to determine the safety and efficacy of a radio frequency device for treating cellulite and circumference reduction.

37 women with cellulite received 8 weekly treatments using a radiofrequency device. Treatment areas included the abdomen, thighs, buttocks, and arms. As a result, there was a significant decrease in the circumference of 3.5 and 1.7 cm in the abdomen and thigh, respectively. 4 weeks after the last treatment, the reduction in abdominal and hip circumference was sustained. A 50% reduction in cellulite was also noted.

The last study [5] was involving 25 women with abdominal cellulite. They received 6 weekly radiofrequency and dynamic muscle activation treatments. Areas of exposure included the abdomen and both sides of the flank. As a result, there was a significant decrease in abdominal circumference by 2.96, and then by another 2.52 cm at follow-up visits 1 and 4 weeks later, respectively.

Based on research, it can be noted that ultrasound is safe, effective, and well-tolerated for improving the circumference and thickness of thigh fat without significant side effects. Also, radio frequency has a beneficial effect on belly reduction and cellulite appearance.

Preparing for ultrasonic cavitation

It is very important to follow the rules of preparation for the ultrasonic cavitation procedure, namely:

  • Don’t drink alcohol 3 days before the procedure;
  • Don’t eat fatty, spicy, or fried foods the day before the procedure;
  • An hour before the session, be sure to drink one liter of water.

It is recommended that you stop using any skincare products one week before your first cavitation session on the areas that will be sonicated. Because these products may prevent the ultrasound from penetrating deeply into your skin.

You should also avoid tanning beds, waxing, or electrolysis during this period.

Proper preparation will ensure that your ultrasonic cavitation session is safe and produces the expected results.

Recommendations after the procedure

  • Mandatory consumption of water

1.5-2 liters of water per day for the entire course of cavitation.

During this period, if the amount of water is carefully controlled, consumption becomes a habit, and one switches to a healthier diet. This is great for overall health, speeds up the metabolism, hydrates the skin, and most importantly, reduces appetite. Consequently, reducing the amount of food you eat will help to speed up your metabolism and lose weight.

  • Stabilization of the diet

During the course of cavitation, it is recommended to eat to switch to a low-calorie balanced diet (especially avoid fatty, fried foods). This habit has a positive effect on the shape of the body and overall health.

  • Minimal physical activity during the day

Constant cardio training or a 30-minute walk a day — speeds up metabolism, helps reduce swelling, and provokes the rapid removal of products of cell dissolution after the cavitation procedure. This habit also restores muscle tone, which affects body contours and skin elasticity. In addition, it is an excellent preventive measure against future swelling and cellulite.

  • Lymphatic massage

After each cavitation treatment, you should have a mandatory massage to stimulate lymphatic drainage. The purpose of this is to speed up the removal of fluid from the body as a whole along with the products of the dissolution of fat cells.

Benefits of using ultrasonic cavitation

Many doctors and patients compare cavitation to liposuction. But compared to the latter, cavitation has a series of obvious benefits. The main ones are:

  1. The treatment is pain-free, and there will be no bruises, cuts, or swelling on the body.
  2. Ultrasonic fat cavitation can be applied to almost the entire body (abdomen, thighs, buttocks, or back).
  3. Increases blood circulation by removing metabolic waste from tissues, which contributes to faster weight loss.
  4. Increases the body’s ability to eliminate toxins, which helps reduce cellulite.
  5. Allows you to work on certain muscle groups to tone and strengthen them, without resorting to hard training.
  6. Ultrasonic cavitation can be done at any time of the year.


Ultrasonic cavitation is a technology that uses ultrasound waves to destroy the fat cells without leaving any damage on the surrounding body tissue. 

It’s not just another fad diet or exercise plan, it does work by breaking down fat cells in your body without any side effects (such as pain, scarring, and downtime).

This fat loss procedure can be done in just minutes per area and will not only help you lose inches but also clear up cellulite too. 

Ultrasonic cavitation treatments are available at local chiropractic offices and even at home. Ultrasonic cavitation treatments are available at local chiropractic offices and even at home.


👨 Can men undergo ultrasonic cavitation?

Yes, the cavitation procedure is indicated for both women and men who want to get rid of fat in certain body areas.

🔎 Is the cavitation procedure painful?

This procedure is completely painless. During cavitation, the top layer of the skin is not damaged, no bruises or scars remain on the body.

🧐 Is there any special preparation required for the cavitation procedure?

Doctors advise to refrain from drinking alcohol for three days before the procedure, not to burden the liver and kidneys with excessively fatty and spicy foods. Also within three days before cavitation, you should drink 1,5-2 liters of water, and 1-2 hours before the session about a liter.

🗓 How long does the effect last?

This procedure does not destroy fat cells but releases them from their contents. In this way, cells again retain their ability to store fat, so a balanced diet is the most effective way to ensure longer-lasting results. If you consume more calories than your body burns, you are likely to experience less of the effects of the treatment over time.

❌ What are the contraindications of using ultrasonic cavitation?

Contraindications to ultrasonic cavitation are oncological and some cardiovascular diseases, diabetes mellitus, osteoporosis, serious dermatological problems, and oncological diseases. It is strongly not recommended to carry out this procedure for those who suffer from renal or hepatic insufficiency because cavitation puts stress on these organs. The presence of pacemakers and any metal implants in the body also precludes this procedure. Pregnant and breastfeeding women should refrain from cavitation too.
