May be because it's a little heavy and clogs pores? I have no idea. I just bought it because Im giving MAC one more chance, I m fed up with MAC foundations because they cause me to have pimples and skin goes crazy, so, my skin s clear and pimples free and I decided to use mac again, this time, Im gonna be the cleanest, lol , I hope I can see a difference, if not, I'm gonna toss it and forget about mac foundations.
