The products really do work—I subbed them for concealer and foundation and got pretty, natural-looking results. I only have two concerns. One, the color correctors are a little too movable and get into the creases under my eyes in no time. And two, they melt quite a bit on my fingers, and I doubt they'd hold up very well in warm or humid weather. Otherwise, though, it's a cute, handy kit for concealing on the go.
