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 Nd:YAG 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 Nd:YAG 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.
