Clinical Observation of Pulsed Dye Laser and Intense Pulsed Light in Treating Facial Telangiectasia

A Clinical Observation on the Efficacy and Safety of Pulsed Dye Laser and Intense Pulsed Light With Different Wavelength Bands in the Treatment of Facial Telangiectasia: a Retrospective, Self-controlled Trial

Facial telangiectasia is one of the common skin vascular lesions characterized by dilated cutaneous vasculatures in the skin surface or mucous membranes. Lesions are generally sensitive to exposure of cold, heat and sun. Those distinct small dilated blood vessels are cosmetically disfiguring for patients which require an effective solution. The traditional management options for facial telangiectasia include cryotherapy, CO2 laser, topical agent, oral estrogens, electrosurgery, and radioactive treatment. However, inadequate outcomes and severe adversaries are the major concerns to patients and physicians. Pulsed dye laser (PDL) is effective for vasodilatory diseases, especially for the superficial to middle layers of the dermis. The intense pulsed light source is an alternative or supplement to the already existing laser devices that are part of the laser surgeon's repertoire. The broad wavelength spectrum and variable pulse duration allow greater penetration depths to be reached without damaging surrounding tissue and thus enhance the versatility of this system. This study aims to compare the clearance efficacy of facial telangiectasia using PDL (595nm) with IPL configured by various wavelength bands, including M22 vascular filter (530-650nm and 900-1200nm), M22 560 (560-1200nm), M22 590 (590-1200nm) .

PDL (Vbeam perfecta, 595 nm, Candela Corporation, Wayland, MA) was used with energy dosages of 9-11J/cm2, pulse durations of 10ms/20ms, and 7 or 10 mm handpieces with dynamic cooling device (DCD)

PDL (Vbeam perfecta, 595 nm, Candela Corporation, Wayland, MA) was used with energy dosages of 9-11J/cm2, pulse durations of 10ms/20ms, and 7 or 10 mm handpieces with dynamic cooling device (DCD). IPL device (M22, Lumenis Limited, Yokneam, Israel) with integration of sapphire ChillTip system for epidermal cooling were used in the study. Three wavelength bands were configured: 560-1200 nm, 590-1200 nm, and vascular wavelength bands of 530-650nm and 900-1200nm. All the treatment handpieces had a spot size of 15mm×35mm, fluence of 9-17J/cm², pulse duration of 4.0-6.0ms and pulse delay of 20-40ms, underwent the M22 advanced optimal pulse technology (AOPT) treatment.
