What the science says
Vitamin C has some evidence for fading dark patches, especially melasma, and most studies found it worked better than a placebo 1. Its anti-aging support has some evidence too, with studies showing smoother texture and fewer wrinkles on sun-damaged skin, though it did not clearly improve hydration 2. For centella, the evidence on redness and irritation is not proven yet, since only one study tested it and found it eased redness more than a placebo after laser treatment 3.
