I did this because of my hooked nose.
It seemed smooth at first, but as time went by, the thread got absorbed... and
later on, my hooked nose looked more prominent.
I had it done three times in total, including retouching, but it seemed like it was for no reason, and maybe because my skin is very thin, I ended up with a dimple scar on the tip of my nose. Well..
If you say ‘Oh’ with your mouth, the tip of your nose will sink in like a dimple..
Think about it carefully before you try it.
For reference, I did it in Incheon and I did it in Gangnam, and I did it both in ㄹㅇㅎㅇㅇ!
