Ultrasound cavitation

What is ultrasound cavitation?

Ultrasound cavitation is a non-invasive treatment that removes localised areas of unwanted fat, with minimal discomfort or downtime. The unwanted cellulite and fat cells are converted to liquid form and eliminated naturally from the body.

It is a less expensive alternative to liposuction, giving similar results but involving no surgery, scars or anaesthetic.

Ultrasound cavitation can be used on almost any area of the body where diet and exercise have not been successful in getting rid of excess fat. The most popular areas we treat are the arms, abdomen, thighs and buttocks.

It can be combined with radiofrequency skin tightening to enhance the results.

How does it work?

Ultrasound cavitation delivers controlled ultrasonic waves into the area being treated.

This causes the emulsification of the unwanted fat, converting it into a substance that is easy for the body to eliminate through the urinary and the lymphatic system.

It not only removes excess fat but also prevents it from recurring in the treated areas.

What happens during the treatment?

During the ultrasound cavitation treatment, the practitioner applies a specially-designed hand piece to your skin.

The hand piece transmits low-level ultrasonic waves that cause ‘cavitation’ in the fat tissues. Cavitation occurs when tiny cavities or bubbles form in response to rapid changes in pressure. This action leads to the breaking down of the fat cells into a more liquid (emulsified) form.

You may feel only slight discomfort from the action of the ultrasound hand piece on your body, and a sensation of warmth, but no pain. (It’s unlikely for the hand piece to become too warm. However, should it feel too warm, we would apply more ultrasound gel to your skin to help cool it down.)

How long the treatment takes depends on the size of the area and the thickness of the fat layer, but most sessions last between 20 and 30 minutes.

Will ultrasound cavitation help me to lose weight?

Ultrasound cavitation is a body-reshaping or ‘body-sculpting’ cosmetic procedure, rather than a way to lose weight or a treatment for obesity.

It can help to reduce stubborn, hard-to-shift areas of fat – such as ‘love handles’ – that have not responded to sustained exercise and diet.

Are there any side effects?

Ultrasound cavitation is a safe, non-surgical procedure that has few if any side effects and little or no downtime.

The ultrasonic energy levels created by the device are carefully controlled to target only specific fat cells and not affect other organs or tissue.

You may experience short-term, mild redness, and some patients report feelings of thirst and nausea. You can help to resolve this by drinking water immediately before and after the treatment.

Before and after your ultrasound cavitation treatments

We recommend that you drink about a litre of water before and after the treatment session. This will help your body to naturally eliminate the emulsified fat.

For best results, you should not drink alcohol for two days after the treatment. The alcohol may interfere with how effectively your liver removes the emulsified fat cells from your body.

We also recommend that you maintain a healthy, low-calorie diet and take regular exercise such as walking or other aerobic activities. Both of these will further help your body to process the fat after the treatment.

How many sessions will I need?

For the best results, we normally suggest a course of between 6 and 10 treatments.

You need to allow at least three days between sessions, to allow your body to completely eliminate the fat.

How long do the results last?

You will see some results from ultrasound cavitation after the first one or two sessions. However, the benefits will continue to be increasingly evident over the whole course of treatment.

Results of body sculpting can be long lasting, but depend on a number of factors. These include the area treated and the individual’s underlying tissue structure, age, metabolism, medication and changes in hormones.

You can help to maintain the results most effectively by keeping to a healthy lifestyle with a low-calorie diet and sufficient exercise.
