Designed with a `Hook `n` Roll` brush, the Benefit Roller Lash mascara hooks and separates every lash, then lifts and curls for an eye-opening look. The shape of the brush and curve-setting formula makes it easy to achieve the perfect volumised curl. Provitamin B5 and serin feature for their lash-conditioning benefits. This water-resistant formula is still easy to take off at the end of the day. On application, gently wiggle the brush starting at the base to ensure you coat every eyelash.
