What the science says
Vitamin C has some evidence for fading dark patches, and most of its 19 studies found it helped, especially in melasma 1. Anti-aging research on vitamin C also has some evidence behind it, and all four studies that tested it directly found it smoothed wrinkles and uneven tone more than a placebo 2. Side effects were usually mild and brief in the dark-spot studies 1, while one anti-aging study reported no irritation and hydration gains were not clearly better than a placebo 2.
