Super Bonder is the cherry on top of Lashing. I Love This Product!

Super Bonder: Maximizes lash Extension retention, captures the adhesive fumes for less irritation. 

After you have placed your last lash extension, wait 2 minutes and then apply a drop of Super Bonder to a microswab and dab the lash line on both eyes (I use a second drop the the other eye). Dry and finish up.
