[Filer] Review of dissolving 7-year and 2-year-old chin filler

Because I have a chin filler, I got 0.5 CC filler 7 years ago and forgot about it, but at some point, I guess the filler was all absorbed, and my chin was visible again, so I got 0.5 CC filler again 2 years ago. In addition to the chin filler, I also got nose filler and lip filler, but there were no side effects. The fact that it disappears quickly...? They say filler spreads, but I think it didn't spread and just disappeared. The lips disappeared without a trace within a week, and the tip of the nose came down again. It didn't spread, but my chin was still there, probably because I got hit twice. Anyway, I was doing well, but I once caught a cold, and suddenly my chin hurts. It hurts more when I touch it. Ah, a side effect of the filler. I thought this was it, so I got an injection to dissolve the filler. On the day, it was a little swollen, but after 5 hours, I could immediately see it melting. My chin got shorter and shorter. Now, it's been 2 months since it dissolved, and when I look at it from the side, my chin is flat again. But it doesn't seem to have completely dissolved, so I got an injection to melt the filler by touching it. I don't know if it will all melt if I get a few more injections, but as I dissolved the filler this time, I felt that even if it was a petit procedure, it would definitely not be an easy procedure, and that it would be difficult to get my chin back to what it was before.  Still, I'm thinking about getting nose filler again. Since I got it once, I'll keep getting it. It works
