Lasting Impression: CryBaby

Mascara that stays put for two weeks.

Always glad to add a shortcut to my makeup routine, I was intrigued by CryBaby—a waterproof, semipermanent mascara that's supposed to last at least 14 days. Roni Mallis-Forgione, a technician at Pipino 57 salon in New York City, curled my lashes with a heated curler before painting on a thick gel solution that builds volume, followed by a black paste (an adhesive base and tiny synthetic fibers). Then a small humidifier blew a cool mist over my lashes to set the mascara. Done! Perfectly separated, ultrablack fringe. What a humongous difference tinted lashes make!
