How to use it Hold the curler up next to your eye, open the clamp and position it over your lashes getting as close to your lash line as possible without pinching your lid. Close the clamp gently—as you always want to be careful with your lashes—and hold down for a few seconds before releasing. For maximum curl, gently clamp down as you move the curler from the base to the tips of your lashes. Follow with primer and mascara, if desired, but make sure your mascara is dry before using it again for extra volume.
