How long is the downtime for nasal fillers before flying home?

Hi everyone! I'm Mega from Indonesia. So I'm planning to get nose fillers while on vacation in Korea, but I'm worried about how long I'll have to stay before I can fly home. I can only take a week off...

So, how many days does the injection scar/swelling usually take to disappear? Can I fly in 3-4 days, or is it safer to wait a week? I've heard some say it's possible right away, while others say it takes a long time. Honestly, I'm confused, haha.

Has anyone experienced this? What was the downtime like? Was there significant swelling or just minor swelling? I'd like to know realistic expectations before I book an appointment. Thanks!
