✦ Synopsis
Background and Objective: Nonablative resurfacing has proven its efficacy in vascular and pigmented lesions, while its capacity of substantial wrinkle reduction is still discussed controversially. We present the treatment results of a 1,450 nm diode laser for facial rhytides. Methods: Thirty facial regions were treated with a 1,450 nm diode laser. Pre-and post treatment pictures were compared by the treating physician and two blinded observers.
Results: Even if mild improvement was rated in up to 35% of the post treatment pictures, a discrepancy shows up in the assessments of the three observers, presenting almost no congruency in the rating of improvement. Conclusions: Our study failed to provide convincing data on the efficacy of nonablative treatment of rhytides with the 1,450 nm diode laser. In this respect, we challenge objective judgment in the assessment of subtle changes in nonablative wrinkle reduction.
