A smart eyelash curler lifts every lash to make your eyes look wide open. It is the perfect tool to bring a little glam if your lashes grow straight down. Use before applying mascara to prevent eyelash damage. Center your eyelashes between the top and bottom rubber sections of the curler. Position it at the lash line and gently squeeze the handles together. Hold for several seconds. Curl the lashes in an up and outward direction.
