A retrospective analysis for facial telangiectasia treatment using pulsed dye laser and intense pulsed light configured with different wavelength bands.J Cosmet Dermatol. 2020 Jan; 19(1):88-92.JC
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, 595 nm) with intense pulsed light (IPL) configured by three different wavelength bands in the treatment for facial 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 (595 nm, n = 38), IPL with M22 vascular filter (530-650 nm and 900-1200 nm, n = 39), M22 560 (560-1200 nm, n = 42), and M22 590 (590-1200 nm, 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 (595 nm) and IPL with vascular filter (530-650 nm and 900-1200 nm) 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 efficacies of treatment for facial telangiectasia, among which PDL (595 nm) and IPL with M22 vascular filter (530-650 nm and 900-1200 nm) had similar and the best clinical efficacy as compared to IPL with other wavelength bands.
