Abstract
Background and Objective
To compare single‐treatment facial skin tightening achieved with the current radiofrequency (RF) protocol with single‐treatment tightening achieved with the long‐pulsed, 1064‐nm Nd:YAG laser.
Study Design/Materials and Methods
A total of 12 patients were treated with RF energy on one side of the face and laser energy on the other. Results were evaluated on a numerical scale (0–12 with 12 = greatest enhancement) from pre‐ and posttreatment photographs by a blinded panel.
Results
Upper face improvement (posttreatment score minus pretreatment score) was essentially the same on both sides (30.2 and 31.3% improvement for laser and RF, respectively, P = 0.89). Lower face improvement was greater in the laser‐treated side (35.7 and 23.8% improvement for laser and RF, respectively), but the difference was not significant (P = 0.074). Overall face improvement was significantly greater on the laser‐treated side (47.5 and 29.8% improvement for laser and RF, respectively, P = 0.028).
Conclusion
A single high‐fluence treatment with the long‐pulse 1064‐nm Nd:YAG laser may improve skin laxity more than a single treatment with the RF device. Further controlled split‐face or very large non‐self controlled studies are needed to conclusively determine the relative efficacies of the two technologies. Lasers Surg.
