Luxury Waterproof Mascara is the only waterproof mascara that I've used that doesn't clump or require lots of rubbing to get it off.  It's really easy to use. It lengthens & separates lashes.  It's an effective waterproof mascara yet gentle on your eyes. It's specially formulated for swimmers, brides, wedding days, athletes and if you work outside in hot weather. too.  ~ Jill
