Are you a boxer?
I would never tell anyone to work their neck unless they really really had to for their sport.
Even if it is for your sport I would advise that you only start training the neck once you have been weight training for a couple of year. That way you can be sensitive to your muscles and you know when they are going to fail.
Lats and traps, pretty much anything that pull a weight toward the body, and from any angle.
no facial exercises that I know of really work.
even if they did, doing them would likely cause more wrinkles in teh skin from all the excess movement (if you believe some of the reasons for developing wrinkles)
besides, facial exercises are SNUP (serve no useful purpose)
