Using these RefectoCil eyelash curl rollers is a breeze. First, clean your lashes to ensure no makeup or oils are left. Then, carefully apply the self - adhesive rollers to your lashes, starting from the base and rolling upwards. Make sure they're firmly attached. Leave them on for a while until you achieve the desired curl. When it's time to remove, gently peel them off. Keep in mind, avoid getting them wet before use as it may affect the adhesive. Also, don't use them on damaged or irritated lashes. After each use, store them in a cool, dry place to maintain their quality and adhesiveness. With proper care, these rollers will keep giving you great curls for a long time.
