Methods Thirty two patients with PWS were treated in order to study the clinical improvement by transforming from 11～16 J/cm 2 at 3 mm spot size (VPW,7～10 ms) gradually to 16～24 J/cm 2 at 4～5 mm spot size (HELP G,15～50 ms). Two patients were biopsied before and after the laser treatment.Results After treatment of 1～8 times(3.19 average), very good results were achieved in 7 PWS, and excellent results were achieved in 15 PWS.Improvement was found in 68.75 % of the patients.Conclusion VPW with HELP G laser at 532 nm appears to be an effective treatment for PWS.
