Lasts: More than 14 hours
8:00 A.M. Apply mascara to top and bottom lashes.
2:30 P.M. After six hours of surfing, still plenty of color on my lashes. (I've used a lot of waterproof mascaras in 30 years of competitive swimming, but this one is quickly becoming my favorite.)
4:00 P.M. Hang out on the beach. It's hot, but the mascara doesn't budge.
5:30 P.M. Reapply before dinner. No clumping or flaking.
10:00 P.M. Use makeup remover to wipe off the mascara—water and soap don't do it.
