Clinical, Histologic, and Ultrastructural Changes after Nonablative Treatment with a 595-nm Flashlamp-Pumped Pulsed Dye Laser: Comparison of Varying Settings

BACKGROUND: The flashlamp-pulsed dye laser has been used for nonablative dermal remodeling. OBJECTIVE: We conducted a study analyzing the clinical, histologic, and electron microscopic findings after treatment with different flashlamp-pulsed dye laser settingss in the same subject. RESULTS: Most subjects showed mild to moderate improvement after flashlamp-pulsed dye laser laser treatment. There was no statistical difference in the clinical, histologic, or electron microscopic findings with a variety of laser treatment settings. CONCLUSION: Nonablative dermal remodeling can be accomplished with not only a variety of different technologies, but also with the same laser using markedly different settings.
