What is a Non Surgical Nose Job

A non-surgical rhinoplasty can reshape the nose with the use of hyaluronic-acid-based fillers. Fillers can help disguise a bump by filling the area above and below it.  Fillers can also help give projection to a nasal tip and/or bridge. Results are temporary but provide instant results. In the long run, this approach is less cost effective compared to a surgical rhinoplasty, since you need to repeat the injections.  Most important is to make sure you are going to a very experienced injector:  injecting the area around the nose can have permanently disastrous results if not done properly. For best results, please see a board certified plastic surgeon with experience in both surgical and non-surgical rhinoplasty.

A  non-surgical nose jobs is also known as  a non-surgical rhinoplasty. This is accomplished by using filler to modify the shape of the nose from an external approach rather than undergoing surgery to alter to internal nasal structures. Non-surgical rhinoplasty is usually not meant to reduce the size of the nose, rather this approach is more often used to straighten the bridge of the nose for people who are concerned about a bump or hump on the nose. Decreasing the appearance of a hump on the nose results in straightening the bridge of the nose, similar to what can be achieved with a surgical rhinoplasty.

Report
A non-surgical rhinoplasty (nose job) is a quick 5 minute in office procedure which is performed with fillers to improve the appearance of the nose with zero downtime. I typically improve bumps on the bridge of the nose, make the bridge look more straight and narrow, refine the tip and turn the tip up a bit. The length of the result depends on which type of filler is utilized. 
Most surgeons, including myself, use hyaluronic acid (HA)  fillers such a Juvederm, Restylane or Voluma. The duration of each of this fillers is longer in the nose than those typically quoted, as it does not move as much as other parts of the face. Juvederm and Restylane-L typically last 9-12 months in the nose and Restylane Lyft and Voluma can last 1-2 years.  I have noticed that on occasion, less is needed over time and in some minor cases only a few times of injections caused a permanent change, perhaps by stimulation a bit of scar tissue to fill in the area.  A nice feature of the HA fillers is that there is a reversal agent that will reverse the filler right then and there if you are unhappy with the results (have never had to do this, but it is nice to know that it can be done). 
Blindness and skin necrosis (death of skin) because of decreased or blocked blood flow to the area is a feared risk of non-surgical rhinoplasty. Despite training and experience, which can reduce the risk, it is never actually zero. Luckily this is extremely rare, and when skin necrosis is treated correctly and promptly, it will can resolve. 
Some will use Radiesse, which is considered semi-permanent filler.  One issue with Radiesse is that there have been some reports of granulaoma formation (infammatory response) and it can make surgical rhinoplasty a bit more difficult in the future.  
For these reasons, I prefer the HA fillers and will use Lyft or Voluma if there is enough soft tissue coverage for a longer lasting result. 
Seek consultation with a board-certified rhinoplasty expert for an in person consultation for an examination and discussion of your surgical and non-surgical options. I hope this helps and best wishes.
