Non-surgical rhinoplasty can be used to augment the nose creating subtle or dramatic changes. Dermal-fillers can be used to create missing contours, fill-in low areas, visually decrease humps, define and enhance the tip, and give the nose an overall "finished" look. Typically, fillers placed in the nose last 6-9 months. Occasionally, some results are longer because the body is stimulated to build it's own collagen in the area.
Depending on your goals, non-surgical rhinoplasty may be a good alternative while considering surgical rhinoplasty. It can be a great way to preview results and make changes for a smaller time commitment
