The short answer to your question is that fillers have been used successfully (I personally have been performing them for about twenty years) for treating a variety of nasal profile issues, most especially bumps and humps, and contouring and elevating the nasal tip for improvement in profile. Filler nose jobs require experience and expertise and should not be left to the hands of novice injectors medspa venues accustomed to treating simple smile lines with ordinary Juvederm of plain Restylane. Make sure to consult with an experienced, board certified cosmetic dermatologist and be certain to ask to see his/her personal before and after photos before agreeing to proceed. Best of luck.
