I got square jaw botox with Geomin a month ago, and it seems to be really effective! People around me keep asking if I lost weight (I actually gained weight, lol), and my face really looks smaller than before.. 50 units cost about 160,000 won, which seems about average? (The really cheap ones cost 90,000 won, and the expensive ones cost 250,000 won. Wow.) Anyway, I'm really satisfied overall.
