title: Evaluation of acne scar treatment with a 1450-nm midinfrared laser and 30% trichloroacetic acid peels.
abstract: OBJECTIVE
  To evaluate the efficacy of treatment of established acne scars with a sequential combination of treatment using a 1450-nm, midinfrared, nonablative diode laser with dynamic cooling spray and 30% trichloroacetic acid peels.
  
  
  METHODS
  In this prospective study 9 patients with atrophic rolling, boxcar, or both types of scars received 4 monthly treatments using a 1450-nm, midinfrared, nonablative, diode laser with dynamic cooling spray followed by 2 bimonthly treatments with 30% trichloroacetic acid peels. Blinded evaluators and the patients rated the results.
  
  
  RESULTS
  The group of patients in this study had a greater improvement in their acne scars than has been reported for nonablative laser treatments by other authors. Comparing the results of treatment 2 months after the laser treatments with 2 months after the chemical peels, the patients had a greater improvement after the additional chemical peels. There were no complications in this study. The patients were able to continue all of their regular activities throughout the study.
  
  
  CONCLUSIONS
  This sequential treatment regimen using the 1450-nm, midinfrared, nonablative diode laser with dynamic cooling spray and 30% trichloroacetic acid peels produced a noticeable improvement in the acne scars without any associated morbidity.
