I bought this bb cream for my sister, who has normal skin, but I've tried it myself too.

The roller system is coll but maybe not the most hygienic one? Not sure.

Even on a normal skin, you can't apply too much, or else it will get cakey. If you apply a thin layer (and by thin I mean normal) you get a medium coverage. I have some imperfections on my face, and I still need a concealer because I can't do a second layer. It doesn't last well on oily skin, since it's quite moist and glowy, but for a normal skin is good.
