How long after getting a nose filler injection can I fly back to Taiwan?

Hi everyone! I'm Tinghui from Taiwan. I'm currently considering non-surgical rhinoplasty with fillers in Korea, but my vacation isn't very long; I can probably only stay in Seoul for about a week. I wanted to ask if anyone knows how long you typically need to wait before flying home after a nose filler procedure? Will there be noticeable swelling or bruising that's obvious to everyone?

I'm a bit worried about being questioned by colleagues or friends when I get back, haha. Has anyone here had this experience and can share? Would it be safer to stay for a few extra days? Also, are there any special precautions I need to take before flying? I'd really appreciate any advice you can offer. Thanks!
