How Does Ultrasonic Cavitation Work to Remove Fat

Does Ultrasonic Cavitation Remove Fat Effectively?

Ultrasonic cavitation treatment is one of the safest ways to remove stubborn fat in your body. It is non-surgical and instead uses sound waves to remove fat beneath the skin.

Ultrasonic cavitation is intended to assist individuals actively trying to lose weight. It tones the body by targeting specific areas and contouring the body to your desired goal.

However, some individuals are concerned if ultrasonic cavitation is effective. Despite these doubts, there is consistent evidence that ultrasonic cavitation is an innovative cosmetic procedure with proven benefits and safety.

If you’re considering starting your journey on ultrasonic cavitation, we will help you learn more about the process and how to experience its benefits effectively.

What to Know About Ultrasonic Cavitation

What is ultrasonic cavitation?

Ultrasonic cavitation is FDA-approved as a non-invasive body contouring procedure. It reduces body fat deposits that do not shed with exercise or diet.

Moreover, ultrasonic cavitation targets adipose fat and cellulite reduction.

This procedure contours your body shape for a better-toned look but does not impact body weight.

This treatment requires patience because it may take a few sessions to reach your goal.

Despite this, it is very convenient because it only takes an hour or so to complete one session.

It is also described as soothing and has no after-effects. There are barely any risks and multiple benefits.

However, this may apply only to people who are close to achieving their weight goal. It is essential that you maintain a healthy diet and exercise regularly. 

A healthy lifestyle cannot be compromised and replaced with repeated cosmetic procedures. They can only assist you in achieving a healthy weight.

Ultrasonic cavitation is the preferred procedure for removing fat cells and improving the appearance of the fatty areas of the body. It can be difficult to remove unwanted body fats in target areas.

Ultrasonic cavitation targeted areas for fat reduction:

  • Thighs
  • Abdomen
  • Hips
  • Face
  • Neck
  • Upper arms

How does ultrasonic cavitation work?

Ultrasonic fat cavitation uses ultrasound technology which applies radio frequencies and sound waves. These waves form vapor bubbles around the fat deposits, which burst and destroy fatty tissues.

Dead fat cells are dislodged from the dermal layers and are liquefied by the sound waves.

The sound waves and radio frequencies cause cavitation phenomena.

Ultrasonic energy is delivered by non-focused or focused waves. It is specifically designed to prevent unwanted tissue injury.

Fat cells cannot withstand the vibrations caused by sound waves. The liquid form of fat deposits turns into glycerol and free fatty acids.

These fats pass through the liver and are excreted as waste.

They are drained through the body’s lymphatic system. It is best used on areas of localized fats but cannot be applied on bony areas of the body.

Its non-invasive method makes the procedure quick and painless. A trained provider will glide a handheld probe over the desired area.

This treatment is done for multiple sessions depending on the amount of body fat it needs to break down.

The lymphatic and urinary systems will gradually flush out the fats, making the process safe and discrete.

Despite their clinical efficacy, the biological mechanism of its liporeductive effects is not fully understood.

Is Ultrasonic Cavitation Effective?

This method is also known as ultrasound-induced fat cavitation.

A 2013 study was conducted on the histological and ultrastructural effects induced by ultrasound cavitation on cell components of human skin adipose tissue.

Despite the existence of procedures like liposuction, its side effects and complications make people hesitant to undergo the knife.

Safety is a priority from the clinical perspective.

Hence a demand for innovation in this non-invasive procedure is desired. Ultrasonic cavitation is the most effective instrument for fat reduction without using surgeries.

Results of the study further support existing evidence on the benefits of ultrasound cavitation.

Its ability to reduce localized fat safely provided consistent findings in the individuals who underwent the treatment.

The safety and efficacy of body sculpting with ultrasound cavitation are further studied in a larger group.

A reduction of circumference and fat thickness were demonstrated with treated adults.

A more recent study investigates the level of leptin in overweight women who accompanied a low-calorie diet with ultrasound cavitation.

Leptin is a modulator of food and energy intake, which is associated with reduced body fat. Lower levels of leptin were seen in individuals after treatment.

Dramatic results in body contour with ultrasound-induced cavitation can be achieved with multiple sessions and appropriate diet and exercise.

How long does it take to see results?

Ultrasonic cavitation treatments will provide results that are visible immediately after just one session.

A reduction of circumference in the area can be experienced with better results on every subsequent treatment session.

Depending on the number of sessions, the difference will gradually improve. In the last session, after the body flushes out the fats, an average of 10 cm circumference reduction can be achieved.

It is important that a healthy diet is maintained during and after the session to accelerate the process and improve fat loss.

Ultimately, changes that occur will vary for every individual.

The desired results will also have different efficacy for each target area and what cavitation devices are used.

Moreover, the fat removal process will be influenced by your metabolism and the density of localized fat in that area. Hence, realistic expectations should be held.

The standard treatment for ultrasonic cavitation is completed in 45 minutes to 75 minutes each session.

And about six or more weeks before significant changes are seen.

Is Ultrasonic Cavitation safe?

Studies on ultrasonic cavitation procedures provide evidence of its safety along with its efficacy.

It is a comfortable and quick non-surgical fat reduction method with little to no side effects.

Unlike surgical liposuction, it does not require anesthesia and incisions.

As a non-invasive transdermal procedure, it only targets fatty tissues beneath the skin. It does not affect blood vessels and does not result in serious side effects.

In certain individuals, if ultrasonic cavitation side effects occur, they are usually mild and eventually disappear.

Redness, mild bruises, and pain are rarely experienced.

It is generally described by people as soothing and relaxing.

Even after the treatment, you can continue with other activities without worrying about feeling tired or sick.

However, people with certain conditions may not be permitted to undergo the procedure. This includes individuals with pacemakers, diabetes, heart problems, or skin disease.

It is recommended that you ask your doctor if you are eligible for ultrasonic cavitation treatment before proceeding.

Pregnant women must also ask their doctors first when they are allowed to start ultrasonic cavitation.

It usually takes a few months after giving birth before a pregnant woman is permitted to start treatment.

What to consider before using ultrasonic cavitation treatments

Non-invasive body contouring by using ultrasound waves is far safer than surgical procedures. However, the results cannot be compared with liposuction.

Your goal should be to improve the appearance of target areas.

If you consider starting this treatment, remember that it aims to get rid of visible fats, cellulite and tone your body.

You cannot lose hefty pounds with noninvasive body contouring.

A healthy lifestyle is ultimately the best method of losing weight.

Additionally, it is not a quick weight-loss treatment. Ultrasonic cavitation can only assist with your progress in reaching your desired body.

Commitment and patience are required to complete the multiple sessions needed to achieve benefits slowly.

You will also have to wait for your lymphatic system to flush out the fatty cells.

Nevertheless, every session is quick and convenient with no downtime periods.

Before the procedure, provide all your health information. This includes medical conditions, medications, vitamins, and herbal supplements you take.

Furthermore, drink plenty of water to facilitate the elimination of broken-down fats and keep a healthy lifestyle even after the treatment.

The fat loss from the procedure can return if you consume too much food, alcohol or become sedentary.

Coolsculpting vs. Ultrasonic cavitation treatment

Coolsculpting treatment is often compared with ultrasonic cavitation. Both are non-surgical procedures and remove fat cells.

However, they use different techniques in reducing cellulite and fats. Coolsculpting uses cold frozen fat cells, while the ultrasonic cavitation procedure uses sound waves.

Coolsculpting can be used on similar targeted areas as ultrasonic cavitation.

They are both safer than surgical liposuction. They are also less expensive.

Nevertheless, ultrasonic cavitation is better when compared with coolsculpting treatment.

Ultrasonic cavitation is slightly less expensive, and the procedure takes less time per session.

Additionally, it is considered a safer procedure and less complicated process than coolsculpting.

How much does ultrasonic cavitation cost?

It is far more affordable than surgical treatments.

The exact costs vary depending on the number of sessions, equipment used, and where you have the procedure done.

It is also less time-consuming, and there are no severe side effects. It is an intelligent choice for people with busy schedules who cannot afford to take a leave at work.


Ultrasonic cavitation is not a quick fix for weight loss. It is a method that reduces fats on targeted areas such as the stomach, hips, upper arm, and face.

Localized fats are broken down by sound waves and excreted by the body.

This process makes it a convenient and safe non-surgical procedure.

The risks of current invasive treatments can be concerning for many individuals. Moreover, the costs are high, and the complexity of procedures adds to it.

Ultrasonic cavitation allows others to choose a healthier method.

However, this treatment should be patiently completed with the recommended number of sessions. The results will gradually appear with every visit.

It is recommended that during and after the session, a low-calorie diet with regular exercise is maintained.

Ultrasonic cavitation can only assist you in accelerating the results of your goal for a healthy and fit body.

Frequently Asked Questions (FAQs)

Are there side effects?

Ultrasonic cavitation is a low-risk treatment and does not have serious side effects. If side effects appear, they are usually tolerable. These effects include redness, bruising, swelling, and headache.

It is recommended that you drink lots of water after every session to help flush out fat cells. If you feel unwell and have persistent side effects, contact your healthcare provider to further evaluate the treatment.

How are fat cells eliminated?

Ultrasonic cavitation uses focused ultrasound to turn fatty tissues into liquid by emulsification. This goes through your liver and is excreted in the urine. Thus, drinking plenty of water before and after sessions is essential.

Is the procedure painful?

Yes, it is a pain-free procedure. Ultrasonic cavitation uses ultrasound energy to promote fat loss in a specific area. This method uses a probe over your skin that will only cause slight heat or tingling sensations. On the contrary, it is considered relaxing. It is less painful compared to both coolsculpting and liposuction.

Does it have contraindications?

Ultrasonic cavitation is not for everyone. It cannot be used as a weight-loss treatment for obesity—people with heart disease, liver failure, and kidney failure. Pregnant women cannot also undergo this treatment.

If you have severe medical conditions, inform your healthcare provider first.

What are its benefits?

Ultrasonic cavitation can reduce stubborn fatty areas of the body that do not shed normally with exercise. Cellulite reduction is also possible with this procedure, along with toning of the body.

Compared with other cosmetic procedures, it is the safest fat-reducing treatment available. Moreover, ultrasonic cavitation does not need anesthesia or surgery for people anxious about going under the knife.

Can it be used for saggy skin?

No, ultrasonic cavitation mainly focuses on the fatty cells beneath the skin. However, there are other cosmetic procedures that can target loose skin.

How many treatments are needed?

The number of sessions will depend on the target area and the amount of fat present. Usually, it takes 6 to 12 sessions to see results.
