1. Apply Last
Put on falsies after finishing your shadow and liner. It's tricky to get a smoky eye just right with extra lashes in the way.
Using tweezers, hold the strip where your own lashes start at the inner corner of your eye. if there's any excess at outer corner, trim.
3. Add Glue
Holding the strip with your tweezers, apply a very thin (as in nearly nonexistent) coat of glue straight from the tube. Swipe your finger over the strip to smooth and remove any excess -- globs of glue are a dead giveaway that you're wearing fakes.
Wait 10 seconds, then place the strip at the roots of your own lashes with the tweezers. Don't stress if you make a mistake. Simply use your fingers to remove any glue and go back to Step 2. Repeat Steps 1–3 on your other eye.
After two minutes, clamp with an eyelash curler -- it will help your natural lashes blend with the false ones. Seal with mascara.
Before removing, wet a cotton swab with hot water and run along the lash band to soften the glue. You'll save your natural lashes.
