Does nose filler really spread out?

I'm considering getting nose fillers because of my low nose, but the more I look into it, the more worried I find.

I have often seen reviews saying that the nose stays high and pretty at first, but over time, the filler spreads sideways, making the nose look thicker or blunter.

On the other hand, there are people who say they have been maintaining it without any problems for several years, so I am confused about what is correct.

I've heard that it appears better on people who have had multiple touch-ups than on those who have only had it done once. Is that actually true?

If anyone has ever had nose fillers...

How long did it last?

I wonder if it really felt like it was spreading

How did the shape of the nose change after the revision procedure?

Is there anything you regret?

Please share your honest experiences! I find nose surgery too daunting, so I'm considering nose fillers and am really curious about actual reviews.
