The Effect of Intense Pulsed Light Treatment on the Vascular lesions
BACKGROUND: The intense pulsed light (IPL) system is a high-intensity pulsed light source which emits noncoherent, defocused, polychromatic light is a broad wavelength spectrum of 400-1200 nm. The mechanism of action of the light system corresponds to selective photothermolysis. Nowaday, the IPL system is widely used in the dermatologic field for the removal of unwanted hairs, epidermal melanocytic lesions, vascular lesions, and for photorejuvenation. OBJECTIVE: The purpose of this study was to evaluate the clinical results of diverse vascular lesions after treatment with an IPL source. METHOD: Forty Asian patients with vascular lesions were enlisted. The IPL treatment was administered to patients in 4-week sessions. Irradiation wavelength was controlled using cutoff filters ranging from 555 to 950 nm, with a fluence of 15-16J/cm2 (except forehead and zygomatic arch area), with single pulse illumination and a pulse width of 7 msec. RESULTS: At the end of the study, three physicians assessed the results and concluded that 72.5 % of the patients showed excellent or good results from the treatment. However, no difference was observed in 62.5 % of the patients after treatments. Furthermore, no specific adverse effects, except two cases of purpura and crust, were observed after the treatment. CONCLUSION: The treatment of vascular lesions on Asian skin using IPL is an effective, safe, and rapid treatment, with relatively few side effects and high patient satisfaction.
