A randomized side‐by‐side study comparing alexandrite laser at different pulse durations for port wine stains

Pulsed dye laser (PDL) represents the gold‐standard treatment for port wine stains (PWS). However, approximately 20% of patients are poor responders and yield unsatisfactory end‐results. The Alexandrite (Alex) laser may be a therapeutic alternative for selected PWS subgroups, but optimal laser parameters are not known. The aim of this study was to assess clinical PWS clearance and safety of Alex laser at a range of pulse durations.
