Juvederm facial areas

The question shouldn't be what facial areas Juvederm can treat, but rather what areas of your face are concerning to you?  Juvederm can be injected almost anywhere in the face.  Some areas are not as good, but with the proper technique and reasons could be attempted.  There may be a better filler option than Juvederm for certain areas and conditions as well.  I would encourage you not to put the cart before the horse.  Figure out for yourself what you would like to improve and then seek the possible answers.
