Think of the children...
There are now worries that Botox injections cause wrinkles to form in alternative non-paralyzed facial areas. Plus:

Last week, there were reports that film producers were turning down actors who used Botox because of its effects on facial expression.

What about babies with Botoxed mothers? (OK, fathers, too.)
Do they miss out on the necessary feedback that they get during interactions with their parents?
I’m basing this hypothesis on news anchors who appear too facially paralyzed to show any emotion whatsoever.
I’ve seen more expressive animatronics.
