Short chin filler 3 times review + Filler dissolving injection

I had a short chin complex, so I got 1 cc to put on the front chin, but after about a year, it felt like it was falling out, so I got 0.5 cc, and after a year and a half, it seemed like it had melted, so I got 1 cc and got irritated. I don't think I was afraid because I was young.. It was my first knife surgery or procedure in my life, and it was the first time I had side effects, so I was so scared and regretted it a lot at the time I got inflammation. It doesn't look good. I think I need to be really careful with the filler.
