The forehead was cut off only in the middle, so I wanted it to be as natural as possible, so I added 3 C. Now that I think about it, I should have added 1 C.. Hehe I felt a tingling and tingling sensation for a while after the anesthetic injection, but I didn’t feel any pain or hardship! He's a tough guy in this area , but he came out well.

For the forehead, I heard that Yves with relatively large particles are good .
