Last summer, I got a contouring injection at a dermatology clinic in Gangnam Station that was said to be safe because it didn't contain steroids. I had a double chin and chubby cheeks, so I weighed 70. ㅠㅠ When I went there, people who looked like they had no facial fat were also there and they were all applying anesthetic cream... In conclusion, it didn't work for me. It was a waste of 70 dollars... I think it might be better to just go to a cheaper place like T.S.O.P or T.S.M.
