Abstract
AbstractBackgroundMelasma is a hyperpigmentary disorder causing cosmetic disfigurement. We aimed to compare the efficacy and safety of tranexamic acid (TXA) microinjections with TXA mesoneedling for facial melasma.MethodsThis randomized assessor‐blind split‐face controlled trial included patients with symmetric facial melasma. One side of the face received TXA (100 mg/ml) mesoneedling and the other side intradermal TXA microinjections. The interventions were repeated three times with 4‐week intervals (weeks 0, 4, and 8). The primary outcome was improvement in modified Melasma Area and Severity Index (mMASI) 4 weeks after the final treatment session. Secondary outcomes were complications and patient satisfaction with the treatments evaluated by a visual analog scale (VAS).ResultsAll 27 patients included in the study were female (mean age: 44.22 ± 8.39 years). Both groups were comparable in terms of mMASI scores before and after treatment (standardized mean difference [SMD] = 0.32, 95% confidence interval [CI] −0.22; 0.85, p = 0.248 and SMD = −0.13, 95% CI −0.66; 0.40, p = 0.633, respectively). The mMASI score change from baseline was not different (SMD = −0.39, 95% CI −0.93; 0.15, p = 0.157). However, patient satisfaction was significantly higher with TXA mesoneedling (SMD = 0.77, 95% CI 0.21; 1.32, p = 0.007). Post‐inflammatory hyperpigmentation occurred in one patient in the TXA mesoneedling group. Erythema, scaling, and edema were significantly higher with TXA mesoneedling (p < 0.001).ConclusionsTXA mesoneedling was comparable with TXA microinjection in the treatment of facial melasma, while patient satisfaction was significantly higher with TXA mesoneedling; however, the high frequency of complications occurring with this treatment should be taken into account.
