Cosmetic Procedures for Treating Lichen Planus Pigmentosus: A Review.

Lichen planus pigmentosus (LPP) is a rare pigmentary disorder primarily affecting patients with skin of color. Currently, comprehensive evaluations for procedural interventions for LPP are limited in the literature. In this review, we assess current procedural options for LPP treatment, focusing on their efficacy, safety, and practical considerations. A comprehensive literature search using PubMed and Embase identified English studies published through December 2024 that examined cosmetic procedures for the treatment of LPP. Keywords included “lichen planus pigmentosus,” “laser,” “chemical peel,” “glycolic acid,” “salicylic acid,” “TCA,” “jessner,” “VI,” “cosmetic procedure,” “procedure”, and related terms. Articles without original data, sufficient results, or human participants were excluded. Data on study design, participant characteristics, procedural details, and clinical outcomes were extracted and reported in this descriptive review. A total of 16 studies were reviewed, which highlighted procedural approaches to managing LPP, including chemical peels (eg, phenol and glycolic acid), laser therapy (eg, Q-switched Nd:YAG, CO2 fractional, Picosecond Nd:YAG, erbium-doped fiber), and platelet-rich plasma therapy. Evidence was limited by small sample sizes, lack of randomized controlled trials, and reliance on case reports and series. Most studies included fewer than 20 participants, limiting the generalizability of findings. In conclusion, procedural interventions can serve as an alternative treatment option for LPP, especially for those unresponsive to standard treatments. Further research with larger cohorts and comparative trials are needed to further elucidate current findings. J Drugs Dermatol. 2026;25(2): doi:10.36849/JDD.9209.
