NCT ID NCT05119413
First seen Jun 27, 2026 ยท Last updated Jun 27, 2026
Summary
This study tested a new cream for melasma, a skin condition causing dark patches. The new cream uses thiamidol instead of hydroquinone, which often causes side effects. 40 adults with melasma tried either the new cream or the standard treatment to see if it works as well but is gentler on the skin.
