Lajos Kemeny: Efficacy and Safety of Fotona TightSculpting®

Non-invasive body shaping is growing in demand. Many treatment options are being offered with promises that are unrealistic in many cases. The aim of this study was to investigate the efficacy and safety of combined treatments of 1064 nm Nd:YAG and 2940 nm Er:YAG (FOTONA SP Dynamis) in non-invasive lipolysis and skin tightening. Ten females were enrolled; the side of their waist or the lower part of their abdomen were treated.

In the first step we used 1064 nm Nd:YAG in PIANO mode with the S11-L-Runner scanning handpiece; the scanning surface was 78 mm x 84 mm and power flux density (fluence/treatment time) was 1.2 W/cm2, at a fluence of 108 J/ cm2. The temperature of the skin surface was kept at 42 degrees Celsius for 8 minutes on each treated site. The skin temperature was checked by a special MatrixView temperature monitor. The second step was to apply SMOOTH mode using the 2940 nm Er:YAG laser and R11 handpiece with a spot size of 7 mm at a fluence of 2 J/cm2 and 2 Hz frequency. Each woman was treated four times, every two weeks.

Body shaping and skin tightening were evaluated 2 weeks after the fourth laser treatment. The effects of body shaping from the combined laser treatment were measured by low-dose native CT, waist circumference measurement and comparative photo documentation, whereas body fat was monitored with bioelectric impedance and measurement of fat tissue with caliper fat clippers. The tissue firmness was measured by ultrasound elastography and by clinical assessment. We have found that this TightSculpting method significantly reduced the thickness of the fat tissue and enhanced the firmness of the skin.
