I have a bit of a chin problem, and while I was stressed about my double chin, I heard that filler at the tip of my chin was safe among fillers, so I put in a small amount (maybe 2cc?) about 4 years ago. It was domestically produced hyaluronic acid, and I didn't like the shape, but it did improve my facial shape. I was satisfied because it was clear. After about 2 years, it seemed like almost all of the filler had gone out, so I went to another hospital for consultation. There was no fundamental improvement, so they recommended implants instead. They said there was still some filler left, but they asked me to add only a very small amount to complement the shape, so I asked for 1cc. I put in just the right amount and was very satisfied. I went to the plastic surgeon yesterday for another consultation, and they said there was still some filler left. I'm satisfied with my current condition because it looks natural. I don't know yet if I'll add more fillers, but if you're stressed because of your short chin, consult with a specialist and get the shape right . I recommend adding a small amount where you catch it.
