Split-face comparison of radiofrequency versus long-pulse Nd-YAG treatment of facial laxity.

ABSTRACT

BACKGROUND AND OBJECTIVE: To improve photoaging skin with laser treatment, multiple sessions have been considered necessary to achieve results comparable with one radiofrequency (RF) treatment. We compared single-treatment improvements obtained by the long-pulse 1064 nm NdYAG laser and RF device. STUDY DESIGN/MATERIALS AND METHODS: In a split-face study, patients with sagging skin were treated once with laser (left side) and once with RF (right side) energy. RESULTS: Improvement judged by six blinded observers was greater for wrinkles and laxity (30% median) on the laser-treated side and essentially the same with both modalities (15% median) for texture, pores, and pigmentation. Improvement was maintained for at least 2-6 months on both facial sides without adverse effects. CONCLUSION: With a single treatment, both the long-pulse 1064 nm NdYAG laser and ThermaCool RF device provide a modest degree of improvement in both wrinkles and laxity of facial skin and similar improvement in texture, pores, and pigmentation.
