I've been having the worst luck with mascara! I can't seem to find one that won't run, or smudge, or flake, regardless of the brand, type of brush, waterproof vs. regular, whatever. I work long days and don't have time to keep checking my makeup - I'm looking for something that can really go the distance, like 8-10 hours. Any suggestions? Or does anyone know of any tricks that help the mascara last?
