What Are the Risks of a Juvederm Nose Job?

I think that the risk of harm is small if properly injected. However, I do not think that juvederm is a good choice for shaping a nose. A thicker filler such as Radiesse or Perlane would do a better job and last longer. On the same note, a nurse making this decision and doing such a procedure might be something that you should think twice about. 

All fillers pose some risk of occlusion if injected into a blood vessel. Juvederm is not of itself more dangerous than another filler. Because it is a Hyaluronic acid filler it is considered safer than some because it can be reversed instantly with Hyaluronidase.  The real issue is the experience and expertise of the injector. They need to understand the risks, areas to avoid, and recognize the signs of vascular compromise and know how to manage a medical emergency should it arise. The incident that caused blindness should have been preventable if the injector had been properly trained. Injections of this nature are for advanced and highly qualified injectors only.

Necrosis of the skin is a real risk factor for injecting Juvederm into the nasal bridge.  There is no FDA indication for injection into the nose.
