Non-surgical liposuction


Non-surgical liposuction techniques use laser energy, radiofrequency, ultrasound or cold (cryolipolysis) to reduce fat. Devices are applied directly to the skin of the treatment area and do not employ injections (as in injection lipolysis) or incisions (as in laser assisted liposuction). Although fat loss is more subtle with non-surgical lipolysis techniques compared to surgical liposuction, non-surgical lipolysis techniques have several advantages including reduced risk, reduced cost, and reduced healing time. Laser, radiofrequency, and ultrasound techniques provide additional advantages of tissue tightening. Because there is no suction involved, terms such as laser lipolysis, cryolipolysis or body contouring are preferred to non-surgical liposuction.

In 2010, Zerona became the first non-invasive lipolysis device approved by the FDA following a randomized controlled trial demonstrating circumference reduction of the waist, hip, and thighs. Zeltiq obtained FDA approval in 2010 for cryolipolysis of the flanks and additional approval in 2012 for cryolipolysis of the abdomen. Strawberry was approved by the FDA in 2013.

On January 21, 2005, Meridian Medical received FDA approval for the Lapex 2000. On December 29, 2008, Meridian received FDA approval for the Lapex BCS. In 2013, the lipo laser division of Meridian Co. Ltd. separated from the parent company to become YOLO Medical Inc., retaining the patents. During this transition, the Lapex line was rebranded as the YOLO Curve. On April 24, 2015, YOLO Medical received FDA approval for the successor to the Curve, known as the Lipofina Laser System.

Low level laser light reduces the stability of adipocyte cell membranes, allowing cells to release their stores of fat without damaging the cell. Because the fat is released into the extracellular space, cardio based exercise is usually promoted after the procedure. Exercise increases lymph flow and is thought to also promote the use of the lipids as an energy source. This is also why adequate hydration is encouraged. The laser technologies are differentiated mainly by the wavelength of light used.

Focused thermal ultrasound techniques work by raising the tissue temperature above 56 °C, resulting in coagulative necrosis of adipocytes, with sparing of vessels and nerves. Passive heating of the skin may also induce collagen remodeling.

Radiofrequency devices work by producing an alternating flow, which creates an electric field over the skin. The electric field shifts polarity millions of times per second, that causes a change in orientation of charged particles.
