How long do I need to wait before flying after a nose filler treatment?

Hello, it's Natsu. I'm considering getting a nose filler in Korea and have a question about downtime.

I often hear that it's best to avoid flying back home immediately after the procedure, but how long is actually considered safe? I know there's individual variation in swelling and bruising, but I'd like to know if there's a general guideline.

Can anyone who has experienced this share their insights? I've heard that the first few days require special attention, but I've also heard that a week is sufficient... Honestly, I'm not sure. I want to plan carefully in advance to ensure a safe return home, so I would appreciate any advice.
