title: Evaluation of a novel flash lamp system (FLS) incorporating optimal spectral filtration for the treatment of photoaging.
abstract: OBJECTIVE
  Improvement in photoaging using laser and Intense Pulsed Light (IPL) modalities is well documented in the literature. We report a prospective study evaluating the safety and efficacy of a novel flash lamp IPL system incorporating a spectral filtration system designed to maximize improvement of facial dyschromias, telangiectases, and skin texture. The device was a prototype xenon flashlamp pulsed light. The novel features of this IPL device are the extended pulse duration and smooth temporal pulse profile.
  
  
  METHODS
  We enrolled 23 patients (22 female, 1 male) of Fitzpatrick skin type I-IV with evidence of photoaging (lentigenes, ephelides, telangiectases, rhytides). Each patient underwent test sites on their back to establish safe treatment parameters. Using treatment fluences of 20-37 J/cm(2), each patient was given 2-4 full-face treatments separated by 3-4 weeks.
  
  
  RESULTS
  Test sites revealed that shorter wavelength filters and shorter pulse durations increased the risk of epidermal injury. Objective assessment by evaluation of pre and post treatment photographs of the face showed an average improvement of 53% in hyperpigmentation, 39% in telangiectases, and 8% in wrinkles. There were no significant adverse effects.
  
  
  CONCLUSIONS
  The novel flash lamp IPL system in this study was safe and effective in reducing vascular and pigment dyschromias in patients with skin types I through IV.
