Can I continue to do facial exercises after a facelift? Are any muscles cut/changed in a way to prevent this?

Hi Bridget.
There is no harm in doing facial exercises after a facelift. A good facelift would usually involve some form of tightening/suspension the internal layer of the face (SMAS). This can sometimes result in some temporary weakness and asymmetry of the face. Doing facial exercises may in fact help this weakness of the facial nerve or muscles to recover. 
I would, however, give it at least 6 weeks after surgery to allow for complete healing before commencing any form of facial exercises.
All the very best in your recovery.

Hi Bridget.  There are no muscles cut in a facelift and the facial function should be normal afterwards. There is a very small chance of damage to the nerves which can produce some asymmetry in movement.CheersDamien

No muscles should be divided in a facelift and your face will move normally after the procedure.
