Using the curler to give eyelashes a curved shape before applying mascara gives eyes a more expressive look. Position the top arch of the curler over the top eyelashes and slowly close so that the eyelashes are gripped between the two halves of the curler. Press with care. Avoid excessive pressure so as not to damage the eyelashes. Press three times to obtain a natural curl, moving from the root to the tip of the eyelashes.
