I had surgery at a place in Nonhyeon that specializes only in double-jaw surgery (not a plastic surgery clinic), and because I have thin, soft skin, surgical swelling that does not go down easily, a slow-recovery constitution + the combo of a major surgery, the major swelling lasted over a year
I hated even looking in the mirror, but in the end, time solved everything, and I’m doing well without any major side effects.
Even people I knew couldn’t tell it was me until I recognized them first, because my face changed so much (in a positive direction).
But it’s only a difference in degree and timing; sagging skin eventually happens to everyone. Saying it won’t happen after shaving down bone turned out to be a lie
