There is nothing worse than raccoon eyes!!! This mascara lasted about 3 hours before it started smearing all over my under eye area. The formula and brush really impressed me at first, not clumpy and gave a sleek finish that looked really great. But I would purchase the waterproof version of this if it exists because it really didn't hold up. I can't even imagine the horror of wearing this mascara on a hot day.... Really disappointing because this is a cult beauty item that has been raved over for so long. If you're looking for a high end mascara, try eyeko instead and spare yourself the smearing.
