Hello,Thanks for your question. Nonsurgical rhinoplasty or liquid rhinoplasty involves the injection of filler material to camouflage irregularities on the nasal bridge and tip. It can make your nose look slimmer in certain situations, but by adding material to the nose, the overall size increases. The most common filler material used is known as hyaluronic acid (HA) filler. Common HA fillers include Juvederm, Restylane, and Belotero. These fillers last 6-12 months before completely absorbing. There are other fillers and fat injections that last longer, but these are used less often. If you are interested in nonsurgical rhinoplasty, I would recommend that you consult with a rhinoplasty specialist for more information.Good luck,Dr. Shah
