This stuff is awesome. It goes from white to your skin tone in seconds. I don't know how it works, but it does! However, one time when I used it, it turned really dark and almost orangish. I'm not sure why. It was just the one time. I don't know if I got a lot of the little dots in it that time or what. Since then, I make sure and shake the container before applying. I haven't had any other issues. There is not really a smell. I have kind of oily skin so I usually can't use anything liquid and this stuff doesn't bother my skin at all. It's definitely worth a try...
