This stuff is absolutely the most awesome primer ever. I have crazy oily eyelids and can only manage to keep my eye make-up from not smudging for like 30 minutes. Finally I have found a primer that can get me through like 3-4 hours without having creased eyeshadow and smudgy liner. It comes in a cute, albeit LITTLE purple genie style bottle, which unfortunately for the cost does not last me that long. But considering how well it keeps my make-up put I am willing to put up with the 16.00 dollar pricetag. It also just as a side benefit happens to work well as an eyelash primer too (when I smudge it on my eye it also gets on my lashes) and helps my mascara stay on longer as well as makes my lashes look a wee bit longer. I have tried other primers, and while this one won't get me though 8 hours, it still is better than anything else I have yet to try!
