Comparative efficacy of short-pulsed intense pulsed light and pulsed dye laser to treat rosacea

초록

Background: Laser and light-based therapies have often been used successfully to treat rosacea. Recently, short-pulsed intense pulsed light (IPL) that emitted pulse durations down to 0.5ms was found to be effective for rosacea treatment.Objective: This study evaluated the efficacy of short-pulsed IPL in the treatment of rosacea compared with pulsed dye laser (PDL) using same pulse duration and fluence.Materials and Methods: Nine patients with rosacea were enrolled in a randomized, split-face trial. Each treatment consisted of four sessions at three-week intervals and followed up until three weeks after the last treatment. Efficacy was assessed by erythema, melanin index, physician's subjective evaluation, and patient's satisfaction.Results: The mean change in erythema index was -4.931.59 for the short-pulsed IPL group and -4.27 +/- 1.23 for the PDL group. The mean change in melanin index was -2.52 +/- 2.45 for the short-pulsed IPL group and -1.95 +/- 1.41 for the PDL group. There was no significant difference in either melanin or erythema index between short-pulsed IPL and PDL treatments, and there were no noticeable adverse events.Conclusions: There was no significant difference between PDL and short-pulsed IPL treatment using the same energies and pulse. Both PDL and short-pulsed IPL were satisfactory and safe for rosacea treatment.
