Brief summary
A double-blind, randomized, split-face controlled trial of 34 female patients with melasma was conducted. All subject were randomized to receive either intradermal tranexamic acid or placebo injection on the right or the left side of their face.
Detailed description
All subject were randomized to receive either 10 mg of intradermal tranexamic acid or placebo injection on the right or the left side of their face. The primary outcome was improvement of melasma lesions assessed by modified Melasma Area and Severity Index (mMASI) score and mexameter examination which includes Melanin Index (MI) and Erythema Index (EI). Measurements were done at baseline and every two weeks for twelve weeks. Additionally, side effects of therapy and subjects' satisfactory assessment with patient global assessment (PtGA) were also documented.
Interventions
The tranexamic acid injection was given intradermally to the facial skin
The 0.9% normal saline injection was given intradermally to the facial skin
