BACKGROUND: Robust evidence regarding the efficacy of topical tranexamic acid (TA) on melasma in Chinese population is lacking.
OBJECTIVE: To evaluate the efficacy and safety of 1.8% liposomal TA and microneedling with 5% TA solution on melasma.
METHODS: Sixty melasma patients were enrolled and randomized to receive 1.8% liposomal TA twice daily, microneedling with 5% TA solution weekly or 2% hydroquinone every night. Objective and subjective assessments were obtained at baseline, 4, 8, and 12 weeks.
RESULTS: 27.8% of patients of liposomal TA group, 33.3% of microneedling with TA solution group, and 30.0% of hydroquinone group were recognized as "more than 50% improvement." At the endpoint, the melanin index (MI) in all treatment groups was significantly decreased, while the improvement of MI in microneedling with TA solution group and hydroquinone group is higher than liposomal TA group. The erythema index (EI) was significantly diminished in liposomal TA group and microneedling with TA solution group. Dermatoscopy and reflectance confocal microscopy revealed decreased brown granules in all groups and reduced telangiectasia in liposomal TA group and microneedling with TA solution group.
CONCLUSION: 1.8% liposomal TA and microneedling with 5% TA solution are both effective and safe on melasma.
