BACKGROUND: There are various treatment modalities for melasma, but none of them are effective on dermal component of melasma.
AIMS: In this study, we decided to evaluate the efficacy of microneedling plus tranexamic acid in comparison with 4% hydroquinone in the treatment of melasma.
METHODS: This is a single-blind randomized clinical trial on 70 participants with 14% dropout, and therefore, 60 patients with melasma completed the study. Patients were randomized based on simple randomization in 2 groups of A (microneedling plus topical 4% tranexamic acid, monthly) and B (topical 4% hydroquinone, nightly). Evaluation of mean MASI score, patient and physician assessments was performed at 4th, 8th and12th weeks of the treatment. Statistical analysis was performed by paired t test, chi-square test and Fisher's exact test, respectively.
RESULTS: Sixty women (30 patients in each group) were completed the study. Mean MASI score in group A was significantly lower at the end of the treatment (6.84 ± 4.31) than at the baseline (12.89 ± 5.16) (P < .01). Mean MASI score in group B was significantly lower at the end of the treatment (7.16 ± 4.38) than at the baseline (13.56 ± 4.88) (P < .01). There was no statistical difference between 2 groups regarding MASI score, physician and patient assessments during the treatment. Percentage of patient satisfaction was significantly higher than physician satisfaction in both treatment groups (P < .01).
CONCLUSION: In our study, the combination of microneedling with tranexamic acid did not differ from 4% hydroquinone in the treatment of melasma.
