A retrospective analysis for facial telangiectasia treatment using pulsed dye laser and intense pulsed light configured with different wavelength bands.

Abstract

Facial telangiectasia is one of the common skin vascular lesions characterized by dilated cutaneous vasculatures. The variety of diameters and difference in depths of lesional blood vessels are the major challenges for effective treatments for Facial telangiectasia. To compare the efficacy and safety profiles of pulsed dye laser (PDL, 595nm) with intense pulsed light (IPL) configured by three different wavelength bands inthe treatment forfacial telangiectasia in Asian populations. A retrospective analysis of hospital records and review on photographs were performed for those subjects with facial telangiectasia (n=160) who were treated in our department from January 2017 to January 2019. Patients were received two sessions of one of the four following laser treatments: PDL (595nm, n=38), IPL with M22 vascular filter (530-650nm and 900-1200nm, n=39), M22 560 (560-1200nm, n=42), and M22 590 (590-1200nm, n=41). The patients in all the four groups showed an overall and significant improvement of indexes of lesional severity and subjective discomfort as well as improvement score of facial telangiectasia after treatment as compared to baseline. In addition, PDL (595nm) and IPL with vascular filter (530-650nm and 900-1200nm) treatments showed significantly better indexes of lesional severity, subjective discomfort, and improvement score of facial telangiectasia as compared with other two treatments. Light devices with various wavelength ranges showed different efficaciesof treatmentfor facial telangiectasia, among which PDL (595nm) and IPL with M22 vascular filter (530-650nm and 900-1200nm) had similar and the best clinical efficacy as compared to IPL with other wavelength bands.
