Efficacy of 1064‐nm Picosecond Laser in the Treatment of Lichen Planus Pigmentosus: A Split‐Face Randomized Controlled Trial

Key Points

To evaluate the clinical effectiveness of the 1064-nm picosecond laser in treating lichen planus pigmentosus (LPP).
Conducted a split-face randomized controlled trial
Compared treatment with 1064-nm picosecond laser against no treatment
Assessed LPP clinical outcomes post-treatment.
Limited effectiveness of the picosecond laser observed in improving LPP outcomes
Recommendations for larger studies with sham controls
Need for optimization of treatment parameters and sessions.

Abstract

The 1064-nm picosecond laser demonstrated limited effectiveness in improving LPP clinical outcomes. Further studies with sham-controlled trials and larger sample sizes are needed to optimize treatment parameters and sessions, and to validate the role of the picosecond laser as a therapeutic option for LPP.
