Could a non surgical nose job be reversed?

A doctor talked me into being able to give the illusion of slightly off my nose being more symmetrical and straighter and doing it during the consult. I regret it as it was part of my unique look and identity. I don't like it being perfectly straight on profile and adding volume made it look bigger and rounder which I hate. Could it be reversed filler dissolved or do I have to wait? And if it lasts 18mo then does that mean by 9 months it'll be half back to normal? Does it break down evenly?
