The best way to keep that bouncy eyelash curl is by locking it in with the best mascara to help "set" them into their curve. The Falsies Lash Lift Washable Mascara is our best curling mascara because it's designed to contract a little while drying which helps lashes retain their lifted, open, upwards tilt. Some people also prefer to use waterproof mascara because it creates a tight seal on lashes that tend to help them stay up longer than washable mascara.
