I had contouring surgery at Wonjin when contouring first came out, not when it was popular. I had the tip of my chin and square jaw, but other than not being able to eat for a day or two, I didn't have much swelling and I'm still doing well without any side effects! I trusted the director more and left it to him, and I am satisfied with it. If you have any questions about the outline of Wonjin, please ask!
