No more raccoon eyes from mascara [SEP] I've been using this product for years since I have redish-blonde hair and after a day of mascara use would have horrible raccoon eyes. It's so much easier than dealing with mascara. The only reason I docked it a star was because I can never seem to get the ratio of the powder to the activator right. I wish there was a better way to measure it. I'm absolutely doing something wrong because I often have to do two applications and I'm leaving it on for 15-20 minutes each time, which is not even remotely within the suggested time range of a couple minutes. It does last for upwards of 3 weeks.
