I received treatment for Han Kwan-jong and tattoo removal at Jamsil ㅅㅁㅌ Clinic, which is famous for Han Kwan-jong and tattoo removal. Han Kwan-jong got much better so I stopped it and am receiving the remaining tattoo removal, but it is not working... I am using a pigment laser for tattoo removal called Ruby Laser and I heard it is effective. I quit sashimi... but I'm not sure. The hospital is very busy because there is only one director, and the people working at the desk generally seem to be in a bad mood... I don't think there's a single person who is kind, so just bear with me! I don’t recommend going unless you’re just looking for treatment for Hangwanjong.
