What's the Difference Between Juvederm Ultra and Ultra Plus?

Juvederm Ultra has a smaller particle size than Juvederm Ultra Plus and is used more superficially in such areas as around the eyes whereas Juvederm Ultra Plus is used in deeper areas such as the to fill in the deep jowl defects. The Juvederm Ultra Plus tends to last longer.

As the other physicians answered, the products differ in their density/concentration.  Juvederm Ultra Plus is best used for deeper areas such as deep nasolabial folds, deep marionette lines, cheek plumping, etc.  Juvederm Ultra is best used for more superficial lines, in these same areas plus lip lines, cheek lines and also for lip augmentation.  Juvederm Ultra Plus can also be used for lip augmentation but should only be used by a very experienced injector in this area.
