Apply so that eyelash glue does not protrude from the roots of your lashes with included brush. Wait ~10 seconds for adhesive to dry—it should turn from milky white to transparent. Dry before bonding. Do not adhere lashes until glue becomes transparent. Keep in mind that once dry adhesive gets on eyelids, it becomes difficult to remove. Stick your new lashes as close to the top of your original lashes' roots as possible. Press lashes down in this order: centre, inner eye, outer eye.
Always patch test. Discontinue use if you feel any discomfort. Follow additional instructions on packaging. Individual results may vary.
