Abstract

Insights

Platelet-rich plasma (PRP) effectively treats melasma, a common skin condition. This meta-analysis confirms PRP

Area of Science:

  • Dermatology
  • Regenerative Medicine

Background:

  • Melasma is a chronic, recurring skin condition with limited effective treatment options.
  • Platelet-rich plasma (PRP) is a novel therapeutic approach for melasma.
  • Systematic evaluation of PRP's efficacy and safety in melasma treatment is needed.

Purpose of the Study:

  • To systematically evaluate the efficacy and safety of platelet-rich plasma (PRP) for melasma treatment.
  • To synthesize findings from existing studies through meta-analysis.

Main Methods:

  • Comprehensive literature search across multiple databases (Web of Science, PubMed, EMBASE, CNKI, Cochrane Library).
  • Inclusion of ten studies with 395 adult patients for meta-analysis.
  • Statistical analysis using STATA 15.1, calculating standardized mean differences and 95% confidence intervals.

Main Results:

  • Meta-analysis of ten studies involving 395 patients showed a significant decrease in the modified Melasma Area and Severity Index (mMASI) score post-treatment (1.18, p=0.02).
  • Combination therapy of PRP with microneedling demonstrated potentially higher efficacy compared to PRP alone or with intradermal injection.
  • Adverse reactions were minor and transient, including local congestion, erythema, hyperpigmentation, and discoloration.

Conclusions:

  • Platelet-rich plasma (PRP) is an effective and safe treatment option for melasma.
  • PRP can be used alone or in combination with other therapies for improved outcomes.
  • Further research may focus on optimizing combination therapies for melasma.
