I have experienced chin filler twice. They all met at Gangnam ㅅㅋㄹㄴ. I asked for it to be round and not sharp as much as possible.
I'm sure I'll have a chin, but it seems like I can't avoid the inverted triangle-shaped chin. It's been about 5 months since I last got the filler, and even though it's been absorbed a lot, the pointy shape is still the same. If you are seeking a shape that is not sharp, we recommend implants rather than fillers.
