Non-surgical liposuction techniques use laser energy, radiofrequency and  ultrasound  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. 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.

MECHANISM: 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.

Ultrasound 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.

Comparison to surgeryCosts may vary depending on treatment area and clinic prices. While it may cost less than invasive liposuction, the cost of multiple treatments do add up. Since it is non-invasive and non-surgical, there is no recovery time. Patients can immediately resume their daily activities.
