First of all, I suggest that you'd better not do it. When I get older, my nose changes easily, and it is uglier than before. There are still many places that need special attention. It's not convenient to go out to play!

If you still insist on doing it, you can go to the university hospital, where there is a good reputation guarantee, or a big hospital, but you must know clearly before doing it to prevent future troubles, and you must be careful!
