How does the COSTIQ eyelash curler work?
Step 1: Set the eyelash curler to 85°C. Gently press it against the base of your lashes and hold for 10 seconds.
Step 2: Move the curler to the middle of your lashes and hold for another 10 seconds. Repeat the same at the tips to curl your lashes fully.
Step 3: Repeat these steps until you’re satisfied with the curl.
Step 4: Always clean your eyelash curler with the included brush to prevent mascara from sticking to it.
Can the eyelash curler be used on all lash types?
Our eyelash curler is suitable for all lash types.
