Just had smart lipo/laser on my neck 2 days ago. Now my smile is totally crooked and one side droops down? (photo)

Should be temporary in most cases.  It depends upon the area treated, numbing fluid, etc your surgeon used.Close follow up with your plastic surgeon is recommended.

Most probably this is caused by inflammation of the marginal branch of the facial nerve. It can happen after liposuction. Please consult with your surgeon for treatment. It most probably will resolve with time. Keep us posted.Hope this helps,Dr. Gus Diaz

Dear Lisa, Thank you for posting your post operative photo with your questions. It appears that you have weakness of you right marginal mandibular ranch of your facial nerve 2 days after Smart Liposuction. Most likely it is due to inflammation follow the liposuction procedure and should resolve soon. Please follow up with your Board Certified Plastic Surgeon. Best wishes, Dr Richard Swift

Liposuction of the neck can cause some facial nerve weakness which results in the lip not being able to pull downward. Often this is temporary and improves with some time.  Best to follow closely with your surgeon. 

This is quite common after liposuction of the chin. It is caused by inflammation of the marginal mandibular nerve on one side. Best to let all the swelling and inflammation resolve and see how it looks. This takes 3 to 6 months. You can put some Botox on the other side to even it out while you wait. Good luck.
