can you lift up a nostril rim with injections?

From your descriptions, I am guessing that there are some structural concerns and asymmetry under the nasal skin. Using a filler to attempt to address the described concerns is not a bad idea.  However, in my opinion, it is unlikely to create the correction that a surgical revision can achieve.  Also fillers will diminish over time.  Addressing the nasal bridge with fillers would probably work, but addressing the flaring nostril with a filler is unlikely to be successful.  Good luck and be safe.John T.

Injections of fillers such as Restylane and Juvederm can be used to address minor nasal imperfections. This should be undertaken by a rhinoplasty surgeon who understands the three dimensional nasal anatomy, both function and cosmesis.  There are limitations to what can be achieved by a filler - often more is not better.
