Efficacy and Safety of Platelet-Rich Plasma in Melasma: A Systematic Review.

ABSTRACT

Melasma is a prevalent dermatological challenge with limited therapeutic interventions. Platelet-rich plasma (PRP) has been increasingly explored for its potential benefits in various dermatological conditions. This study aimed to systematically review the efficacy and safety of PRP in the treatment of melasma. A comprehensive search in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was executed in January 2024 using PubMed, focusing on studies investigating the efficacy and safety of PRP in melasma. Criteria for inclusion were clinical trials and controlled studies examining PRP's role in melasma treatment, while exclusions covered reviews, non-English articles, and studies older than 10 years, among others. Eight studies were included, with the majority targeting female participants. The research displayed consistent positive outcomes, whether PRP was used alone or synergistically with treatments like hydroquinone and tranexamic acid. However, positive studies with the combination of PRP and other drugs will not provide the actual safety and efficacy data of PRP. The combined treatment approaches often showed enhanced results. Satisfaction rates among patients and reductions in the melasma area and severity index (MASI) scores were common findings across the studies, emphasizing the potential of PRP in melasma management. In conclusion, PRP emerges as a promising therapeutic intervention for melasma. Whether as a standalone treatment or combined with established methods, PRP presents significant potential in melasma's clinical management, warranting further expansive trials to substantiate its long-term efficacy and safety.
