Create a natural-looking lift: The curler can give a natural-looking lift to straight or downward-facing lashes, making the eyes appear more open and awake. Separate and define lashes: The curler can help separate and define each individual lash, creating a more fluttery, voluminous look. Prep for mascara: Curling your lashes before applying mascara can help the mascara adhere better to the lashes, creating a more defined and lengthened look. Fix mascara mishaps: If you've applied too much mascara and your lashes are clumping together, an eyelash curler can help separate them and create a more natural look. Touch up throughout the day: If your lashes start to droop throughout the day, a quick touch-up with an eyelash curler can help bring them back to life.
