Here is a quick thing I just tried
I put a "handle" on the eyebrows and tagged it

I then used the webcam - head goes crazy distortion.

Not a great feeling! So restrict the scope of warping using sticks. I put one between the eyes and eyebrows to try and stop the eyes from being distorted. Then some up near the hair as well. Try things to see what works best for your puppet.

After the sticks in place, it restricts what can warp. See the eyebrow still goes up, but now the hair and eye are not (as badly) distorted.

Turning on the mesh can help understand why things distort.


The whole stick above the eyes gets pulled up, causing the slight eye distortion. You can add pins as well since its an independent layer to try and stop things moving as much. I threw things around the eyeball to stop it distorting, then pins to stop it moving. Just try things!

Final result I got:
