Will Bellafill last forever in nose bridge? Or should surgery last longer?

Localized defects and depressions of the nose are ideally suited for correction with an injectable filler.It is not intended to replace a primary rhinoplasty rather to correct minor irregularities and deformities.
Suneva the distributor of Bellafill shows results lasting up to five years.  PMMA microspheres compose twenty percent and collagen eighty percent of Bellafill.  The microshperes do not reabsorb or decompose; the amount of collagen produced surrounding the PMMA changes with time and age.
Results vary from patient to patient.  Several injections sessions are typically required to produce the desired end result. Bellafill is only FDA approved for injection in the naso-labial folds and acne. Other applications are considered off label use.
Most patients elect to have a less permanent filler injected for the first time to see what can be done. Afterwards they often choose Bellafill to give longer lasting results. 
Please consult in person with an experienced Board Certified Plastic Surgeon prior to making treatment decisions.

Thanks for the question.
If on exam your physician determines that you are a candidate for liquid nose job and you can get benefit from that ... I would definitely go with Bellafill ... unless you are not a candidate, which is totally a different scenario 
Best of luck :)
