LESC Ultrasonic Liposuction

The LESC (Liposuction with External Simultaneous Cooling) cold-ultrasonic liposuction system addresses the primary limitations of conventional ultrasonic liposuction — tissue heating and thermal injury risk — by maintaining the probe tip at a controlled temperature of 25°C throughout the procedure, even as ultrasonic energy is delivered at 30–40 kHz. The cooled probe transmits ultrasonic cavitation energy into the fat layer while preventing any thermal…

The mechanism of fat removal combines ultrasonic cavitation with gentle tumescent suction. A tumescent solution (dilute local anaesthetic with adrenaline) is first infiltrated into the treatment zone; this solution serves triple duty — providing local anaesthesia, causing vasoconstriction to minimise bleeding, and creating a fluid environment within which the ultrasonic probe generates stable microbubbles. When these microbubbles collapse (acoustic…

A notable secondary effect of the LESC method is skin tightening. The ultrasonic energy and the physical suction at the interface between the fat layer and the overlying dermis create a mechanical stimulation of dermal fibroblasts, promoting collagen contraction and new collagen synthesis in the reticular dermis. Clinically this means the skin over the treated area does not typically look loose after fat removal — in contrast to aggressive conventional…
