title: Treatment of facial port-wine stains with a new intense pulsed light source in Chinese patients.
abstract: BACKGROUND
  Intense pulsed light (IPL) systems have been used for the treatment of port-wine stains (PWS) for more than 10 years. Some of them have been reported in the treatment of laser-resistant PWS.
  
  
  OBJECTIVE
  To conduct a prospective trial to assess the efficiency and complications of a new IPL source in the treatment of PWS in Chinese patients.
  
  
  METHODS
  Thirty Chinese patients with PWS without previous treatment were recruited to receive IPL therapy for three to eight treatments at intervals of 4-5 weeks. There were 24 female and six male patients.
  
  
  RESULTS
  One hundred percent of patients showed more than 25% clearance, and 30% of the patients were able to achieve more than 75% clearance. About 70% of patients experienced 25-75% clearance, among them 53.33% of patients experienced 50-75% clearance. There were no long-term complications or side effects.
  
  
  CONCLUSIONS
  The new IPL system can be safely used in treating PWS in Chinese patients of skin type IV.
