Intradermal Tranexamic Acid Injection for the Treatment of Melasma: A Pilot Study with 48-week Follow-up.

Despite being an effective treatment for melasma, there have been limited reports on the long-term efficacy of intradermal tranexamic acid (TA) injection. This study sought to evaluate the 48-week efficacy of a 4mg/mL intradermal TA injection for the treatment of melasma.
