Ultrasound cavitation at CoLaz clinics

Ultrasound cavitation is a non-invasive body contouring treatment that uses low-frequency ultrasound waves, delivered through a handpiece moved across the skin, to create microscopic pressure changes inside localised fat cells. Those pressure changes disrupt the cell membrane and liquefy the stored fat content. The released fatty acids then travel through the lymphatic system, the body's drainage network, and are metabolised by the liver over the following days. There is no cutting, no needles, no anaesthetic and no recovery time. The handpiece feels warm on the skin and most patients describe a high-pitched humming sound in the ear that fades as soon as the session ends.

The treatment is designed for localised pockets of fat rather than overall weight loss. The most commonly treated areas are the stomach and lower abdomen, the love handles and flanks either side of the waist, the inner and outer thighs, the bingo-wing area at the back of the upper arms, and the bra-strap fat at the back. We always confirm the realistic outcome for your specific area at consultation, with photographs and a circumference measurement so progress is tracked objectively across the course.

All three are non-surgical body contouring treatments, but they work differently. Ultrasound cavitation uses sound waves through a handpiece on the skin surface, with no needles. Electrolipolysis uses low-frequency electrical currents through fine needle electrodes or surface pads. Fat freeze uses controlled cooling to crystallise the fat cell, which is then naturally eliminated over the following weeks. At consultation we will recommend the protocol that fits your area, your skin type and your tolerance for needles, and in some cases we combine more than one across a treatment plan.

A full course is typically six to twelve sessions spaced one week apart, with the exact number depending on the size of the area and the amount of fat to be reduced. Smaller areas often respond well to a course of six, larger areas usually need eight to twelve. The protocol is agreed at your free consultation, and course pricing is confirmed in writing before any session is booked so the cost is clear from the start.

No, there is no downtime. The treatment is fully non-invasive and you can return to work, the school run or normal life immediately. You may notice mild redness in the treatment area for an hour or two and a feeling of warmth for the rest of the day. Drinking plenty of water and walking for thirty minutes the day after each session helps the lymphatic system clear the released fat content faster, which is why hydration is part of the protocol rather than an optional extra.

We do not treat patients who are pregnant or breastfeeding, who have a pacemaker or any other implanted electronic device, who have a history of significant heart, liver or kidney disease, who have active cancer or who are within five years of cancer treatment, who have epilepsy, or who have an active skin infection in the treatment area. Patients with metal implants in the treatment area, a bleeding disorder or very thin skin need a specific discussion at consultation. We always review your medical history in full before agreeing the protocol.

A single session is £149. A course of six is £594, working out to £99 per session. The course recommended is matched to the size and number of areas at your free consultation, and the full price is confirmed in writing before the first session is booked. There are no upsells in the chair and no hidden charges, and the consultation fee is redeemable against any treatment you book.
