Tranexamic Acid for Melasma: What a New Meta-Analysis Found
By Mahmoud Mohamed Samir · Published 25 October 2026 · 2 min read
A 2026 systematic review and meta-analysis in Dermatologic Therapy has looked again at tranexamic acid for melasma, and the picture is more nuanced than the headlines around it suggest: the strongest signal is for tranexamic acid used together with hydroquinone, not on its own.
Melasma is a common and persistent concern for our patients in the Maldives, where year-round UV exposure and deeper skin tones make relapse likely, as we explain in why pigmentation and melasma are so common here. At our Hulhumalé clinic, that is why any melasma plan starts with sun protection.
What the review found
The authors pooled 32 randomised trials with 2,376 participants and 14 different comparisons, searching the literature up to September 2020 and updating in January 2024. Tranexamic acid showed little to no clear difference in skin lightening compared with placebo, and no clear difference compared with hydroquinone. Where it did stand out was in combination: tranexamic acid plus hydroquinone performed better than hydroquinone alone, and the authors concluded the combination was superior to either agent by itself.
What this does not prove
The trials used different doses, routes and combinations, and the combination result carried very high heterogeneity, so the size of the benefit should be read cautiously. The review also began with an open question about a possible link to blood clots, and the authors call for further studies, so this is not a reason to start tranexamic acid without proper screening. Regional availability of specific products and regimens varies, and we cannot say what any particular pharmacy in the Maldives stocks.
What tranexamic acid for melasma means for you
Sun protection remains the foundation, with tranexamic acid, where suitable, one tool among several.

Frequently asked questions
Does this review show tranexamic acid works for everyone with melasma?
No. Against placebo and hydroquinone alone the review found no clear difference. The clearest benefit was when it was added to hydroquinone, and suitability still depends on your own health history.
Can tranexamic acid replace sunscreen?
No. Ongoing sun exposure is the main driver of melasma relapse, so daily sun protection stays essential whatever else is used.
