title: A retrospective study of the efficacy of a new intense pulsed light for the treatment of photoaging: report of 70 cases.
abstract: BACKGROUND
  Intense pulsed light (IPL) system incorporating optimal pulse technology has been developed to enhance the efficacy and safety of the treatment of photoaging. However, there are few clinical studies on the treatment of photoaging using the novel IPL.
  
  
  OBJECTIVE
  To determine the efficacy and safety of a new IPL for the treatment of photoaging.
  
  
  METHODS
  We performed a retrospective study and reviewed photoaged skin lesions from 70 patients who were treated with IPL between May 2010 and February 2011. Two independent dermatologists performed assessment of global scores for photoaging. Patients were asked to rate the results and to report any adverse effects by phone interview.
  
  
  RESULTS
  The main problems of patients offered treatment were dyspigmentation, wrinkle, skin roughness, and telangiectasia. The patients received four to five treatments at 3- to 4-week intervals. After three to four treatments, 77.1% and 74% of patients experienced improvements in overall and pigmentation, respectively. 59 patients responded the phone interview expressing satisfaction of treatment. 89.8% of patients rated their overall improvement as excellent or good. No one reported severe adverse reaction.
  
  
  CONCLUSIONS
  The novel IPL is an effective and safe treatment option for photoaged skin.
