There is a large plastic surgery clinic in Ulsan, which is a place where 4 hospitals were merged.
Before the merger, I received eye and occipital canthoplasty surgery from a person specializing in eye plastic surgery, and the double couple line was removed once even though it was a very small incision. So, it is
currently buried elsewhere. The raw line was re-established, but the problem was the back opening.
The torn area showed red skin and had not healed. It's been 5 years.
If anyone wants to do it there, I don't recommend it... Another person who did it there said he had to do it again after having his double couple come off twice.
