How Does Ultrasonic Cavitation Work?

Jason Moe- April 3rd 2022

Ultrasonic cavitation works by using low-frequency sound waves to break down fat cells beneath the skin’s surface. It may lead to fat loss and reduced inches in the treated area.

What should I expect from my first ultrasonic cavitation?

If you’re considering booking an ultrasonic cavitation treatment for the first time, read on to find out everything you need to know to prepare.


Before undergoing ultrasonic cavitation, you should have a consultation with the doctor who will be performing the treatment. They’ll be able to examine the areas you want treated, discuss your goals and advise you on your expectations and the number of treatments you may need.


At the start of your appointment, you may be asked to put on a paper gown, depending on the area being treated. The doctor will then sterilize the treatment area using alcohol, before running a handheld ultrasonic device over the treatment area.

During the procedure, you’ll hear a buzzing sound from the machine, and you may feel a warm sensation on the skin being treated. If you have ever been pregnant, you may recognize the sensation from ultrasound scans. Treatments typically last 15-75 minutes.


As ultrasonic cavitation is a non-invasive treatment, you won’t need much aftercare. The treated area may feel swollen and tender for a few days following your treatment and you may experience bruising. You can use over-the-counter pain relief to manage this, but always talk to your doctor about pain management first.

Your doctor may advise you to stay hydrated, follow a healthy diet and avoid alcohol and nicotine in the days following treatment. This will help the broken-down fat leave the body as energy and waste.

It may be up to 12 weeks before you notice the full results of your treatment, as it takes time for your body to expel the broken-down fat.
