Say goodbye to your eyelash curler! Roller Lash, a real roller for your lashes! For what type of makeup? Its Hook'n' Roll™ brush grabs, separates, lengthens and curls lashes for an enlarged look... while the instant curl formula lasts 12 hours. It contains provitamin B5 and serine agents, known for their revitalizing action on the eyelashes. How to use it? Your eyelashes have never really appreciated the eyelash curler, I must admit. Apply Roller Lash with a gentle zigzag motion from root to tip of lashes. Repeat the operation all along the lash line so that you don't forget any of them. Curves that never end!
