Borboleta Eyelash Extension Primer Our eyelash extension primer prepares the surface of the natural lashes for a better bond with the eyelash extension adhesive by cleaning the natural lashes and removing any extra proteins or oils. This primer for lash extensions gently dries the lashes, which allows the extensions to adhere longer to the natural lashes. Instructions: Begin each application of primer for eyelash extensions by first removing any make-up with oil-free make-up remover or soap and water. Apply a small amount of eyelash extension primer onto 2 disposable microfiber brushes for eyelash extensions. Place one underneath the lashes, and one on top of the lashes. Gently glide lash extension primer up the eyelashes to cleanse each lash thoroughly. Make sure lashes are completely dry before applying the eyelash extensions.
