I have been performing nonsurgical nose jobs for the past twenty years, since the very early days with Radiance, the forerunner of Radiesse and nowadays with injectable hyaluronic acid volumizer and filler products. When I first started, nonsurgical nose jobs with these products was limited to camouflaging nasal bumps and humps. What was happily discovered is that often by improving the nasal humps, the rest of the nose appeared more tapered. (In time, the uses of nonsurgical, filler rhinoplasty expanded to include elevating droopy nasal tips, correcting nasal spine irregularities left by aggressive surgical nose jobs, and even to improving some forms of side wall asymmetries.) Without at least a profile photo, it is really impossible to say whether this procedure is right for you. However, in general, the short answer to your question is that it is possible to achieve the kind of improvement you desire by this means. In my NY office, I typically choose Restylane Lyft for these purposes, whereas in my Israel satellite facility, where a far greater number of regulatory agency approved fillers are available, I would opt for Hyabell. As to how much it would cost, that would depend upon the particular material or materials needed to get the job done, the amounts, the location of treatment and the experience and expertise of the injector. Fees in my neck of the woods may range from 750-1500. The nose is not a place for novice injectors trained to inject simple Restylane or Juvederm into ordinary smile lines. Make sure that you consult with a board certified aesthetic physician and insist upon seeing his/her personal before and after photos before agreeing to proceed. Best of luck.
