title: Microresurfacing using the variable-pulse erbium:YAG laser: a comparison of the 0.5- and 4-ms pulse durations.
abstract: BACKGROUND
  Laser resurfacing has become less popular because of its long recovery time, significant discomfort, and potential risks. Microsurfacing employs the use of single-pass erbium:YAG (Er:YAG) "mini peels," which may be performed serially.
  
  
  OBJECTIVE
  The purpose of this study was to evaluate the efficacy and patient acceptance of microresurfacing Er:YAG peels in treating facial photodamage. The variable-pulse Er:YAG system was used and was allowed a comparison of the 0.5- and 4-ms pulse widths.
  
  
  METHODS
  Six female patients underwent eight microresurfacing peels in a split-face fashion using the 0.5- and 4.0-ms pulse durations of a variable-pulse Er:YAG laser. Patients returned at postoperative Days 3 to 4 and 7 for clinical evaluation and Mexameter measurements.
  
  
  RESULTS
  There were no significant differences in healing or postoperative erythema between the 0.5- and 4-ms pulse durations on postoperative Day 7. The average time to reepithelialization was 3.6 days. In a 1-year postoperative interview, four of six patients said that they would undergo the peel again periodically, and five of six stated they had maintained some level of improvement.
  
  
  CONCLUSIONS
  Microresurfacing is an effective and well-tolerated procedure. Benefits include its tolerability under topical anesthesia, limited down time, and high patient satisfaction.
