A Retrospective Study on Efficacy of Pulsed Dye Laser and Intense Pulsed Light for the Treatment of Facial Telangiectasia.J Drugs Dermatol. 2017 Nov 01; 16(11):1112-1116.JD
<p>Both pulsed dye laser (PDL) and intense pulsed light (IPL) systems have been demonstrated to be effective for treatment of facial telangiectasia, however there have been very few comparative studies between both treatments involving purely Asian patient populations. In this study, we performed a retrospective analysis to compare the efficacy of PDL and IPL systems for the treatment of facial telangiectasia. A total of 416 patients with facial telangiectasia who were treated by PDL or IPLs in our department from August 2012 to March 2015 were included in this study. The subjects received one of the following five treatments: PDL 595 nm (9-12 J/cm2), MaxG (500-670 nm & 870-1200 nm, 30-46 J/cm2), IPL (560-1200 nm, 18-24 J/cm2), M22 560 (560-1200 nm, 15-18 J/cm2), and M22 590 (590-1200 nm, 15-20 J/cm2). Each treatment had two sessions with 6-week intervals. The improvement percentage score in facial telangiectasia after the final treatment was evaluated by two non-treating physicians. We found almost all patients (less than 95.00%) had marked improvements or nearly complete clearance of the lesions after PDL 595 nm or MaxG treatment, as compared to 41.38%-56.58% patients in the other three groups that showed similar degrees of improvements. Both PDL 595 nm (9-12 J/cm2) and MaxG (500-670 nm & 870-1200 nm, 30-46 J/cm2) treatments resulted in significantly superior vessel clearance than the IPL systems with other wavelength bands (560-1200 nm or 590-1200 nm) and relatively lower fluence (15-24 J/cm2). Our results also suggested fluence levels account for the significant differences in the effectiveness delivered by different IPL systems. We concluded that PDL 595 nm and MaxG showed comparable clinical efficacy and both treatments resulted in most beneficial outcomes.</p> <p><em>J Drugs Dermatol. 2017;16(11):1112-1116.</em></p>.
