Treatment of striae distensae with non-ablative fractional laser: clinical and in vivo microscopic documentation of treatment efficacy.The efficacy of NAFL in the treatment of striae distensae (SD) has been demonstrated.  NAFL represents an effective and safe treatment modality for SD.  We report herein in vivo variations occurring in SD after NAFL treatment.

The aim of this study is to describe in vivo variations occurring in the skin after the treatment, using reflectance confocal microscopy (RCM).  Clinical and RCM images were acquired before the treatment, immediately after 1 and 6 months after the first treatment.  RCM revealed the dissolution of collagen bundles and the appearance of new papillae, as compared to baseline.
