My nose has definitely become more defined than before, and I got a 6-month filler, but it seems the claim that filler does not completely disappear is true, because my bridge still looks like it has more height than it did at first.
I heard repeated procedures are risky, so I haven't had it done again since the first treatment ㅠㅠ I'm also worried about nose surgery, so I haven't been able to mess with my nose any more.. Anyway, for people with no bridge between the brow area and the nose, filler seems to work pretty well.
