Glue Stop prevents your lash adhesive from travelling up and closing your lash fans. It works with all eyelash adhesives! Apply it with brush 1mm from the bottom of the lash line (while lashes are still on the glue strip) and work as you normally would. When room temperature is up to 22 degrees, re-apply twice a day. When room temperature is more than 22 degrees, re-apply when you see that fans no longer stay open.
