Cream showdown: which melasma treatment works best?
NCT ID NCT07522788
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study compares two topical creams—tranexamic acid and ethyl ascorbic acid—for treating melasma, a condition causing dark patches on the face. About 128 adults aged 18 to 50 with melasma will apply one cream nightly for 12 weeks. Researchers will measure improvement using the Melasma Area Index Score to see which cream reduces pigmentation more effectively.
