Anastasia has one of the most innovative, best ideas around with Lash Genius. It’s a clear waterproofing topcoat to use over any mascara. Since waterproof mascara is so hard to remove, most women don’t use it daily but would like their formula to stay in place at the pool, gym, or for special events like weddings- which is why I have it in my kit. I can instantly turn any of the 5 or 6 mascaras I carry into durable waterproof formulas without having to change a thing about the tubes I’ve come to rely on. It’s especially helpful to lock in color on the lower lashes which often times become notoriously smudgy.
