This may sound like a nice concept, but injectable fillers are no solution to use in place of rhinoplasty. Nearly every type of cosmetic nasal procedure including septoplasty and rhinoplasty almost always involve removing tissue and not adding any. This is especially true with the tip: no one undergoes changing the tip to make it larger [or adding matter] it is always to make the tip narrower or smaller. This is across the board no matter what ethnicity you may be, from Caucasian to African-American. With septoplasty nearly 90% of the time it involves bringing the nasal bones closer together [hence slimming the septum] so adding matter cannot do this. The only circumstances where a injectable filler could work on the nose is if you have very little projection of the bridge (more common in people of Asian descent) and want to build up the bridge - in this circumstance injecting Radiesse or equivalent could be a short-term solution. Another way it may benefit is if the bridge has below average projection with a defect such as a dorsal hump or other bump that could be camouflaged by extending the bridge outward using a filler so it is not visible. My estimate would be in over 95% of patient complaints regarding their nose, an injectable filler would not offer any type of improvement.
“One popular new plastic surgery technique is called lip grafting, or "fat recycling" wherein fat cells are removed from one part of your body that is too large, such as your buttocks, and injected into your lips; people will then be literally kissing ass.”
