Randomized controlled trial evaluates laser treatment effectiveness in lichen planus pigmentosus, suggesting need for more research.
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.
