What’s the Difference Between Cavitation and fat Freezing?

A question I’m often asked as a trainer of both of these treatments, and one you may likely be asked as a therapist, is ‘What’s the difference between fat freezing (cryolipolysis) and ultrasound cavitation?’

Both are fat reduction treatments, yes, but they both work in very different ways and use two very different technologies. The fundamental key to helping clients choose the best option is to be able to explain the difference. So, here’s my quick guide to differentiating the two treatments:

Fat Freezing (Cryolipolysis)

Fat Freezing (Cryolipolysis) TreatmentFat freezing is best for targeted, stubborn pockets of fat, especially those that seem resistant to diet and exercise. It’s a slow, gentle and much more natural approach to fat reduction and as such will take up to 12 weeks to see maximum results.

This is not the treatment for those who want fast results or a quick fix but it is for clients who want effective results but can’t commit to once/twice a week sessions and are willing to put the work in. Diet and lifestyle changes are a must in order to support the treatment during this 12-week process but it is incredibly effective if done and supported correctly.

Fat freezing (cryolipolysis) uses cold temperatures to trigger a process known as apoptosis. This process destroys the complete cell, including the nucleus, which means the cell cannot regenerate itself and so the fat cell is PERMANENTLY destroyed. 


Ultrasound Cavitation

Ultrasound Cavitation TreatmentI tend to refer to this treatment as the ‘quick fix’ treatment. It’s the one that will give instant, visible results from the very first treatment. It’s also the treatment that’s the better option for treating a larger area.

It’s important to note that this treatment will give progressive results, meaning that the more treatments people have, the better results they will see. Due to this most people will recommend a course of 6-12 treatments to clients.

Another vital difference is the way the fat cell is damaged by the treatment. Ultrasound cavitation causes the fat cell to implode, so the liquid fat spills out and is metabolized by the body. It does not kill the nucleus of the cell so over time the fat cell will reform itself. This is turn means ultrasound cavitation is a SEMI-PERMANENT treatment.

Both treatments do require clients to maintain a healthy diet and lifestyle in order to preserve their results as fat cells in the body can replicate and multiply … ill cover more about that in another post. However, I hope you’ve found this quick comparison useful, so please do drop me a comment with your thoughts or questions.



  1. Hi with the cavitation machine is the training online ?

    1. Hi Carly, only the theory is online. You do a face to face practical too.
