Nasolabial fold filler vs midface filler? (Photo)

Based on the photo, you have loss of volume in your mid face. By filling the midface with a filler like Voluma you can improve the NLFs . You can also have Juvaderm injected into the marionette line as well some in the NLFs. 

it does depend somewhat on your budget.. you clearly need mid face volume restoration.  i cant see your jaw line but you probably need lifting also.. injecting the cheek bone and mid face will give you a much better appearance but will require much more filler.
