What the science says
Arbutin has some evidence behind it for fading dark spots, as most of the nine studies found it helped patches look lighter 1. Studies on melasma, a pigment condition, often found patches became lighter, and one measured a drop in skin darkness 1. The most common side effects were mild redness and itching, though some studies reported none 1.
