Will Fillers Correct the Hump on my Nose?

Fillers may "mask" nasal contours but won't "correct" them
It would not be accurate to say that you can "correct" a dorsal hump with fillers because fillers are temporary. A permanent correction requires surgery and the dorsal hump is the easiest thing to fix about a nose. Fillers have been used for a few years and new reports keep popping up now about the hard to correct problems being seen from this practice.

Slight bumps or deviations can be managed, albeit temporarily, by injections of fillers to camouflage or disguise the appearance of the irregularity.
In many instances, this requires maintenance and peramnent long term correction commonly requires surgery.
