Insights

Platelet-rich plasma (PRP) effectively treats melasma by reducing severity and pigmentation. This study shows significant improvement in melasma symptoms after intradermal PRP injections, offering a promising therapeutic option.

Area of Science:

  • Dermatology
  • Regenerative Medicine

Background:

  • Melasma is a common hyperpigmentation disorder.
  • Platelet-rich plasma (PRP) is increasingly explored for dermatologic treatments.

Purpose of the Study:

  • To evaluate the efficacy of intradermal Platelet-rich plasma (PRP) in treating melasma.

Main Methods:

  • Fifteen female patients with melasma received three sessions of intradermal PRP every three weeks.
  • Melasma Area and Severity Index (MASI), melanin index (MI), and erythema index (EI) were measured.
  • Patient self-assessment scores (PSS) were recorded before and after treatment.

Main Results:

  • Mean MASI decreased from 10 ± 3.6 to 7.3 ± 2.5 (p=0.001).
  • Mean MI reduced from 256.5 ± 31 to 238.9 ± 29.9 (p=0.000).
  • Mean PSS decreased significantly from 8.3 ± 1.3 to 5 ± 1.4 (p=0.000).

Conclusions:

  • Intradermal PRP is an effective treatment for melasma, improving skin appearance.
  • Continued use of depigmenting agents is recommended post-treatment due to melasma's common recurrence.
