A Dear Joshawna101 ....While certain fillers, techniques, and placements are able to give an appearance of a more narrow nose, it will not make the nose appear smaller. Filler is meant to AUGMENT an area as you're injecting (adding a substance to) an area.
While it can be used to correct a bump or a deep scar on a nose - it is used to fill in cratered areas or depressions in the nasal bridge, but it will not be used to make it appear smaller.
However, an experienced botox injector can perform an injection just below the tip of the nose, frequently referred to as a "tip flip" that has a tendency to release the pull of the nasal tip down and help it "flip up".
Thank you for your great question and for the opportunity to answer!
