because i have fairly deep-set eyes, i always have the problem of my eyeshadow creasing and moving during the day. it's driven me nuts for a long time, but i didn't think there was anything that could be done about it. booooy was i wrong! i went in to sephora over the weekend and casually mentioned it while talking with an SA, and she recommended this: Urban Decay Eye Primer Potion http://www.sephora.com/browse/product.jhtml?id=P74310&shouldPaginate=true&categoryId=3806 i used it today for the first time and it worked SO WELL. i put it on this morning and my eyeshadow was still fully intact and perfect at 10 p.m. tonight when i got home. i also didn't have any eyeliner stuck above my eye, which happens sometimes. i'm utterly amazed. i thought i'd let y'all know so that you can try it if anyone else has this problem.
