These Dermadoctor Kakadu C Intensive Vitamin C Peel Pads With Ferulic Acid and Vitamin E ($78) make my skin feel so smooth after just three minutes, and they've even lightened some of my dark spots, too. (Be sure to always have sunscreen on as vitamin C makes skin more sensitive to sun.) And, while they're gentle enough for daily use, I use these two or three times a week and still see results (and I cut them in half to make them last even longer).
