To prevent damage to your eyelashes, start by removing the mascara from your eyelashes. Mascaras that harden the eyelashes cause them to fall out and break while curling. Therefore, be sure to clean your eyelashes. Start by holding the eyelash curler towards your eye. With your eyes open, turn on the curler and place your lashes between the clamps. Then gently turn the curler on and off a few times and wait 5-10 seconds. In this way, your eyelashes will look fuller and longer. Returns of opened and used products are not accepted.
