暂无%X <B>BACKGROUND: </B>Melasma, a chronic acquired skin pigmentation disorder, is characterized by the presence of irregular-edged brown to gray-brown patches with a symmetrical distribution, primarily on sun-exposed areas such as the face. Topical hydroquinone (HQ) is the gold standard for melasma treatment but has numerous side effects. This study assesses the effectiveness of topical tranexamic acid (TA) as an alternative for melasma treatment.<BR><B>METHODS: </B>In a double-blind, split-face, randomized controlled trial involving 20 subjects, the effectiveness of 3% TA versus 4% HQ cream was evaluated over 8 weeks. The modified melasma area and severity index (mMASI), melanin index, erythema index, and side effects were assessed. Subjective improvement was measured using the patient global assessment (PtGA).<BR><B>RESULTS: </B>A significant decline in the mMASI score was observed at weeks 4 and 8 in both groups compared to baseline. There were no statistically significant differences in PtGA scores between the 3% TA group and the 4% HQ group.<BR><B>CONCLUSIONS: </B>Topical 3% TA is as effective and safe as 4% HQ for treating melasma in the Indonesian population, with potential advantages in terms of side-effect profiles.
