Treatment of post-pulsed dye laser purpura with pulsed dye laser.

The pulsed dye laser (PDL) is used for the treatment of a variety of vascular and nonvascular disorders, and its therapeutic efficacy often depends on purpura as an endpoint. However, post-PDL purpura is an undesirable side effect of treatment as it may increase patient dissatisfaction and downtime. Recent studies have suggested that repeat treatment with PDL may speed the resolution of post-procedural purpura; however, there is paucity of data on using repeat PDL treatment specifically for post-PDL purpura.

Combined Treatment with Botulinum Toxin and 595-nm Pulsed Dye Laser for Traumatic Scarring.

Traumatic scars on skin covering areas of high movement, especially areas on the face, can be stressful for patients. We report two cases of traumatic scars that occurred on the chin, and that were successfully treated with a combined therapy of 595-nm pulsed dye laser (PDL) and intramuscular injection of botulinum toxin. After the treatment, good cosmetic results were achieved in both patients.

Treatment of periorbital syringoma by the pinhole method using a carbon dioxide laser in 29 Asian patients.

Background: Pinhole method has been used to treat various types of scars and dermal tumors by making multiple small holes in target tissues of the deep dermis using an ablative 10,600-nm carbon dioxide (CO2) laser.

Objectives: We prospectively investigated the efficacy and safety of using a CO2 laser to treat periorbital syringomas via the pinhole method.

Methods: A total of 29 patients with periorbital syringomas were treated with two sessions of CO2 laser treatment using the pinhole method at two-month intervals.

A patient with cupping-related post-inflammatory hyperpigmentation successfully treated with a 1,927 nm thulium fiber fractional laser.
