For those not interested in a traditional nose job, the non-surgical option makes use of fillers such as Radiesse or Juvederm to smooth out nasal bumps and humps and, at times, correct breathing issues.
A non-surgical Rhinoplasty or nose job uses some kind of filler (Juvederm, Radiesse) to fill a deficit in some part of the nose. This works well if the nose has a pushed in appearance on one side or the other. If the nose has a mild to moderate hump it can be softened quite well by injecting filler just above and below the hump.
Non-surgical rhinoplasty procedures do not make the nose smaller. Instead, fillers add bulk to the bridge to make the nose straighter. Fillers can even out bumps, indentations and irregularities in the nose. The only way to remove the excess bridge is to have surgery.
