What if the airless pump is no longer working and there is still product inside?

The problem can often be attributed to an air bubble inside of the actuator. Most times, this will dislodge when banging the bottle on a hard surface and rolling the bottle a few times.

Is the pump still not working? Then you will need to lend a helping hand (or in this case a paperclip):

Take a paperclip & fold it open.	Insert it in the opening at the bottom of the bottle.
