Lack of Mouth Movement, Unable to Blink or Pucker: All Results of Facelift?

What you are describing is a problem with your facial nerve. 26 days post-surgery this is very unlikley due to swelling - especially because of your eye symptoms.  So you need follow up with your surgeon to determine if this is a temporary or permanent injury to the nerve. You also need to make sure that your eye is protected. Prolonged exposure during sleep can lead to a corneal injury.

You are describing could involve just the buccal branches of the facial nerve. The buccal branches will supply the muscles that affect the muscles that make the smile.  The blinking issue could also be the effect of the buccal branch of the facial nerve.  An actual examination is needed to know precisely your issues.  It is likely that the surgery injured one major branches of the buccal nerve.  These can recover or the  injury may be permanent.  One concern with the blink is corneal drying.  An oculoplastic surgeon can assess you for eye drying.  However, I would not be in a hurry to have more surgery.  There may be some recovery of function and this can take several months.  A second opinion is reasonable and appropriate.
