It has been quite a while, and I did this with an event price, so I am not sure about the exact cost. I got 1 cc and remember it was within 90,000 to 120,000 won.
I visited to get lip filler for the first time in my life after seeing the event. The director was kind and everything was good, but they filled my upper lip so unevenly that I went back for a touch-up after just one week. T_T When they checked my lips, thankfully they added 0.5 cc more for free.. But maybe because of that, or because my lips take filler well, it lasted a year and a half even though it was originally supposed to last 6 months. lol After the touch-up, I liked the shape too. Still, being left so uneven was shocking, so I never went back after that. T_T
