I'm not precisely sure what you're trying to do (an image may help!), but if you want to match-move a beard to a person's face, you will need to export the tracking data, not the shape data.
The shape data is just for masking the footage. The tracking data will move a layer in AE to match the motion of the object you have tracked.
You may need to watch a few tutorials to get an idea of how this is done:
