    TLDR PRP treatment improved skin pigmentation and appearance in facial lichen planus pigmentosus.
    This prospective pilot study investigated the efficacy of platelet-rich plasma (PRP) in treating facial lichen planus pigmentosus. The study included a small sample size of 15 participants who received PRP injections over a period of 12 weeks. Results indicated that PRP treatment led to a significant improvement in pigmentation and overall skin appearance in the majority of participants, with minimal side effects reported. The findings suggest that PRP could be a promising therapeutic option for facial lichen planus pigmentosus, although larger studies are needed to confirm these results.
