Occassionally I do use fillers in the nose. The safest areas to inject are along the nasal dorsum over the bone and dorsal nasal cartilages. Injecting the nasal tip can be a bit more risky and could result in compromise to the nasal skin vasculature. I would recommend only using hyaluronic acid fillers - like Juvederm or Restylane, they have a soft "gel like"
substance and are reversable if neede
