I need a list of at least 5 top plastic surgery clinics (face, body & breast)
in Korea that are considered the best in the country (judged by what
authority(s)?). I need contact information.

Im not sure but be careful in the ones you decide. There have been
shops set up over there that offer dna injections and supposidly the
injections will make you look younger. In reality they can have some
awfully bad side effects. And they do not make you look younger.
