The Liposonix treatment lasts for about an hour and is performed after an initial physician consultation. The result is an average reduction of 1 inch around the waistline. Slight discomfort may be felt during the procedure in the form of a prickling sensation, as well as a warm or cold feeling as well. After the treatment, there may be mild redness, bruising, or swelling around the treated area. The Liposonix treatment is permitted for use in the US, Canada and Europe.
