Background: Melasma is a chronic skin pigmentation disorder, and intradermal injection of tranexamic acid (TXA) is an effective treatment option for melasma with limited comparative efficacy studies. Objectives: To compare the effectiveness of TXA injections with other treatment modalities for patients with melasma, as measured by Melasma Area and Severity Index (MASI). Methods: A total of 17 eligible randomized controlled trials were included in the meta-analysis. The MASI and the modified MASI served as the primary outcome measures of treatment effectiveness. Patient satisfaction was also evaluated. Results: Among the various administration routes for TXA, intradermal injection and microneedling demonstrated superior effectiveness, followed by oral administration and topical application. As for patient satisfaction, oral administration outperformed the injection method, whereas topical administration significantly underperformed injection. Furthermore, TXA injections were more effective than the majority of non-TXA standard treatments for melasma. Conclusions: This meta-analysis and systematic review suggested that intradermal TXA injection is an effective alternative for melasma treatment, with potential advantages over other administration routes.
