Laser lipolysis with dual-wave length diode laser corrects skin laxity

Laser lipolysis using a dual-wavelength diode laser with a cumulative energy of 5 kJ/100 cm² skin area resulted in progressive skin tightening over time in the facial, submental, breast, arm and waist regions without general anesthesia or hospitalization.

In the prospective, cross-sectional study, 41 patients underwent laser lipolysis to correct contour deformities. Two wavelengths were tested: 924 nm and 975 nm. Three different tip lengths for treating small, medium and large areas of adipose tissue were also used.

Researchers found the treatment led to progressive skin tightening over time at all treated sites.

Regardless of the body site, significant differences in circumference values were observed in all patients between preoperative and immediate postoperative measurements, and between postoperative day 90 and both the preoperative and immediate postoperative measurements.

Three months after laser lipolysis, skin texture very similar to normal, and researchers observed a noticeable improvement in adipose tissue distribution.

There were no complications, such as ecchymosis or prolonged erythema.

The researchers believe that a cumulative energy ranging from 3kJ to 5 kJ/100-cm² skin area obtains the best aesthetic result.

Other benefits of this treatment include the use of local anesthesia, with no need for general anesthesia, no hospitalization requirement and a quick recovery for the patient, the researchers noted. Finally, there is a short learning curve for plastic surgeons who have previous laser system experience.-by Abigail Sutton
