It's 2019, so it's been 3 years since I got it, maybe it's domestically produced hyaluronic acid?? I must have been hit and I remember that less than 1cc was put in. (It's hard to see) There were two big lumps right after I got hit, but it wasn't too uncomfortable so I just lived with it, but how long ago has it been moving...? It feels a bit like a foreign body and is uncomfortable. I just searched on Naver and saw an advertisement specializing in ㅅㅈ removal, so I searched here and it didn't seem to be very good... And it was more expensive than I thought, but removing the filler costs almost 10 times more than getting it applied... ??? Is it really like that? ㅠㅠ Let me tell you some reviews from people who have had lip filler removed.
