Fat Freezing vs Fat Cavitation: Which one is better for you?
Comparing fat freezing (Cryolipolysis) and fat cavitation to find the best non-invasive fat reduction treatment for your need. Learn about the mechanisms, efficacy, and suitability for long-term results.
Non-invasive fat reduction procedures have gained popularity in recent years. These non-surgical treatments offer the best of both worlds, reducing stubborn fat without the downtime of traditional surgeries like tummy tucks, and liposuction. These procedures can be used for fat loss in areas like the belly, thigh, love handles, chin, neck, upper arms, and more.
This article will compare and provide a better understanding of the mechanisms, effectiveness, safety, and suitability of two of the most famous methods in non-surgical fat reduction treatment including: Fat freezing / Cryolipolysis, or also known as Coolsculpting, which involves freezing the area of the body with unwanted fat leading to the destruction of a thin layer of the subcutaneous fat cells. And fat cavitation or ultrasonic cavitation, which utilises ultrasound technology to reduce fat cells.
Non-surgical Fat Reduction Treatments Comparison:
Fat Freezing and Fat Cavitation
Understanding Fat Cavitation (Ultrasonic Cavitation)
-
Fat cavitation is a non-invasive method to destroy fat cells by using low-frequency sound waves or low-frequency ultrasound which is administered by a handpiece that releases waves into the subcutaneous tissue. The sound waves create bubbles (cavitation) in the cells. Cavitation reportedly bursts the targeted fat cell wall and the liquid fat is then expelled through the membrane of the fat cells leading to fat reduction in the area. The liquid fat is said then to be removed from the body via the lymphatic system. This method is often advertised to treat cellulite and fat loss in specific areas such as the thighs, stomach, and back (bra rolls).
-
There are many blogs and websites on the internet that claim the superior effects of fat cavitation on fat reduction. The research around it has shown improvement in cellulite with temporary skin tightening. However, there has been little evidence to show that it results in permanent fat loss in the area. The mechanism of removal of the cells is not fully understood, some studies claim fat cells are removed with the lipid while others claim the fat is removed but the cells remain. This puts into question the long-term efficacy of ultrasonic cavitation as the cells can gradually refill with fat.

Pros:
Enjoyable procedure with a heating effect
Often compared to a warm massage
Non-invasive and pain-free
Zero downtime
Temporary tightening and temporary decrease in visible cellulite after a few sessions
Cons:
Requires multiple sessions over 6-12 weeks for visible fat reduction
Not suitable for pregnant or breastfeeding women
Not recommended for people with coagulation disorders
It should be avoided by those with a history of malignancy
Not safe for individuals with cardiac pacemakers or other metal implants
Understanding Fat Freezing (Cryolipolysis)
-
Fat freezing/ cryolipolysis is a process that uses cold temperatures to remove fat. This fat-freezing treatment is conducted by using a paneled or cupped device to transmit a temperature that is low enough to target only fat cells while not affecting the surrounding skin, muscles, and nerves. This freezing effect triggers the crystalisation and death of the fat cell which is subsequently digested by immune cells called macrophages and removed via the lymphatic system. This method has been used successfully in areas such as the chin, underarms, back (bra rolls), love handles, stomach, thighs, calves, and knees.
-
Fat freezing has been studied extensively in both animal and human models. The results have been excellent with visible and fast results. The effects can be visible in as little as 2-4 weeks after treatment with final results showing up to a 25% reduction in fat. This efficacy is seen with only 1-2 sessions, proving its superiority. Fat reduction is permanent during freezing because the cells are removed from the area, leading to a long-lasting solution to stubborn fat pockets and bulges. Patients are highly satisfied even after just one session of this therapy because of this effect.
A study by Krueger et al. (2014) quotes two additional studies and states, “The clinical efficacy and safety of cryolipolysis has been studied in both human and animal models. In two separate studies, animal models demonstrated a reduction of up to 1 cm or 40% of the total fat layer thickness after a single exposure without harming the overlying skin.” (Manstein et al., 2008 & Zelickson et al., 2009)
An additional reference included in this study - refers to the article by Coleman SR et al, titled “Clinical efficacy of noninvasive cryolipolysis and its effects on peripheral nerves” States that “in a study published in 2009 involving ten subjects reported a 20.4% and 25.5% reduction in the fat layer 2 months and 6 months after treatment, respectively

Coolsculpting / fat freezing is proven to result in permanent fat loss with as little as 1 session. It is performed without general or local anaesthetic.
There is often an initial feeling of tugging and pulling as the tissue is drawn into the vacuum handle and 5 - 7 minutes into treatment there is often a feeling of slight stinging (as the skin becomes numb). After treatment clients mention numbness and tingling due to the cold temperature however this usually resolves within a few days.
The sessions may be repeated if the fat layer is thick or if the desired results are not met with the initial session. The delay from treatment time to seeing the full results at 12 weeks often is seen as a negative of fat freezing, however, most clients see a reduction occurring within 2-3 weeks.
The 12 weeks is the total duration of expulsion of the fat cells via the lymphatic system. The faster and cleaner the client’s metabolism and circulation, the quicker the results will appear.
Cryolipolysis is more expensive per session than other non-invasive treatments, but the need for fewer treatments while getting maximal benefits makes it an optimal choice. It’s not recommended for pregnant women and those with abnormal cold sensitivity like Raynaud’s phenomenon.
Pros:
Proven to result in permanent fat loss with as little as 1 session
Performed without general or local anesthetic
Most clients see a reduction within 2-3 weeks
Effective results at 12 weeks due to expulsion of fat cells via the lymphatic system
Need for fewer treatments compared to other non-invasive treatments
Cons:
Initial feeling of tugging and pulling during the procedure
Slight stinging sensation 5-7 minutes into treatment as the skin becomes numb
Post-treatment numbness and tingling due to the cold temperature, usually resolving within a few days
Sessions may need to be repeated if the fat layer
Fat Freezing vs Fat Cavitation
-
Fat freezing has proven to be superior to fat cavitation in terms of long-term changes. The results from fat freezing procedures permanently remove the fat cells so the changes remain as long as the person maintains adequate upkeep through diet and exercise. On the other hand, fat cavitation leads to tightening which can be immediately noticeable but the result doesn't show longevity.
-
The science behind fat freezing/ cryolipolysis has been studied extensively in numerous clinical trials and peer-reviewed studies. These studies have proven its results, permanence, and longevity. It has even received medical endorsements. While the studies around fat cavitation are increasing, it has not been as comprehensive as fat freezing. There seems to be more anecdotal information than scientific evidence to support the claims.
-
Fat cavitation is a painless procedure. The rubbing motion of the device coupled with the heat it radiates makes it akin to a massage. The procedure is enjoyable, making the need for multiple sessions tolerable. Even though fat freezing/ Coolsculpting is associated with mild discomfort in the target area, it is not painful. These symptoms usually disappear within a few days. Since there is less need for repeat sessions, the symptoms are bearable.
Suitability for Different Needs
Fat cavitation and fat freezing are both non-invasive, painless, and quick procedures to remove fat. Fat cavitation has less scientific backing but is used for temporary body contouring solutions. Fat freezing/ Coolsculpting has a mountain of scientific evidence backing the fact that it leads to effective fat reduction. A single session can achieve visible results, and it is a permanent solution. Fat freezing is often chosen by clients after a consultation for non-invasive fat reduction due to its obvious advantages. Its superior results are proven by their positive experiences.
-
As a non-invasive therapy, fat cavitation is suitable for individuals who are looking for painless, quick treatment with minimal downtime. It can even be done on your lunch break! This treatment is ideal for clients seeking temporary body countouring and tightening for events and photoshoots. It is also recommended as a temporary procedure to decrease the appearance of cellulite. So if you are looking for temporary changes, ultrasonic fat cavitation is the procedure for you.
-
Fat freezing is also a non-invasive therapy suitable for clients looking to reduce fat with no downtime or invasive procedures. It is the best fat reduction treatment to ensure permanent changes. It also has additional body contouring benefits with fat reduction. It is painless, although mild discomfort may occur. It is most suitable for individuals willing to invest in a clinically proven, effective, permanent solution to unwanted stubborn fat.
