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

Overview

1. 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. 2. 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. 3. 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) .
