Beyond efficacy: pulse duration is crucial for adverse events in pulsed dye laser therapy for rosacea.

In 30 seconds

This randomized controlled trial evaluated the efficacy and tolerability of 6 ms versus 10 ms pulsed dye laser (PDL) treatments in 80 patients with erythematotelangiectatic rosacea. Both pulse durations significantly improved erythema, but the 10 ms setting was associated with fewer adverse events, particularly edema and purpura, which were more common with the 6 ms duration.

Key findings

• Both 6 ms and 10 ms PDL treatments significantly improved erythema (p < 0.001).
• Edema occurred more frequently with the 6 ms setting (p < 0.05).
• Purpura was significantly more common with the 6 ms duration (p < 0.001).
• No significant differences in patient global assessment or symptom improvement between groups.

Why it matters

Understanding the impact of pulse duration on adverse events in PDL therapy is crucial for optimizing treatment protocols for rosacea, enhancing patient comfort and safety.
