Check this out: Juvederm is a family of injectable hyaluronic acid dermal fillers which are used for 9 months to one year of correction for moderate to severe facial wrinkles and folds. There are sometimes negative side effects such as redness and bumps which must be checked out. If the line you mention is still not filled in please check on this with the doctor who gave you this treatment.
