How does HIFU differ from other non-surgical treatments?

For decades, many techniques and technologies have been utilized in an attempt to remove unwanted fat. HIFU is a unique and effective breakthrough in treating localized fat deposits without surgery. 
lipo laser uses a diode laser light source for non-invasive body contouring of the waist, hips, and thighs. The light is shined on the area(s) of the body being treated; multiple treatment sessions are required. Studies have suggested that this laser wavelength partially disrupts the fat cell membrane, allowing the lipid and fatty contents of the fat cell to leak out, and thereby promotes fat cell collapse. The clinical studies showed impressive results at two weeks, but longer term patient follow-up is absent. In addition, it seems to work best when used with diet supplements and exercise. Unlike an ultrasound wave, laser energy cannot be focused to specific layers below the skin. 
coolsculpting is a medical device that relies on controlled cooling for non-invasive reduction of local fat deposits. This process, called cryolipolysis, is based upon the premise that fat cells are more easily damaged by exposure to cold temperatures than skin cells. The cold temperature, which is actually above the freezing point, destroys fat cells beneath the skin. There is a reduction in the fatty tissue layer over several months as the body’s processes clear away the destroyed fat. Limitations of this technology include the prolonged treatment time, the lack of specificity in the treatment application, and the inability to provide specific sculpting and contouring to different body areas. Patients can also experience prolonged numbness or hypersensitivity, due to the effects of the cold temperatures of cryolipolysis system on the nerves of the skin.
HIFU uses a high-intensity focused ultrasound wave (HIFU) to permanently destroy fat cells at a specified depth below the skin. The other techniques lack this same specificity of fat cell destruction. The method by which HIFU delivers this focused ultrasonic energy is very efficient and allows direct treatment of specific body areas, and treatment times of about one hour. The high-intensity ultrasound procedure is used to reduce stubborn fat bulges in the tummy, thighs or hips. There is no preparation required and no anesthesia necessary. On average, HIFU patients lose one inch off their waistline, an equivalent to dropping one pants size or one dress size.
