I got lip filler at a hospital famous for lips in Hongdae. If there is any filler left over from other places, it can be done after it has been dissolved. When I show him a picture of the lip I want, he roughly matches the size and injects it, saying "Oh my gosh, I'm sorry" and "Ta~keuk" without a soul, but it's not bad. Maybe it's because he's had a lot of lip filler done, but he's very good at it.
