Classic idol Yunho of TVXQ has the tendency to look somewhat uncanny, so it’s no surprise that he would end up on our request list. However, I don’t believe he’s had any plastic surgery.
There are a few reasons why his face might look a bit “off”, and none of these reasons can be attributed to going under the knife. First of all, he’s got quite a manly face with a strong jaw, which makes him look slightly more unnatural when wearing make up than your average flower boy. He also had work done on his teeth some time ago, and now sports some exceptionally straight, white veneers. I think veneers can make a person look very different and sometimes even strange. He probably also uses botox which can make the skin look a bit tight (see last pic).
As far as his features go, nothing else seems to have changed. Same nose, eyes, chin as always!
