Curlers work best on clean eyelashes. Make sure eyelashes are free of mascara. If necessary, use eye makeup remover to remove old mascara.
Open the curler, clamp lashes near the roots. Hold for 10-30 seconds. Never curl lashes after you apply mascara, as the mascara dries, lashes can stick to the curler & be torn from the roots. Don't bother curling bottom lashes.
Repeat on the other eye.
Now you are ready to apply your mascara and false eyelashes.
