Unfortunately, this mascara does indeed leave black under your eyes after wearing it for so long. I did not try the waterproof version of it, which might not leave black marks. This mascara does flake throughout the day to. Regardless of these minor issues, you can do a black smokey eye and use this mascara. Or just apply a light coat on only your upper lashes and avoid the flaking. I still use this mascara because it is so volumizing and I love the wand! Hope this helped!!
