Ladies who have had injections, can you share your recovery time?

Hi everyone! I'm Vy, from Vietnam. I'm planning to go to Korea in the next few weeks to get a nose filler, but I'm not too sure about the recovery time. I'd like to know how long it takes for the swelling to go down after the injection and if I can fly home normally?

I'm worried that if the swelling lasts too long, people back home will ask what happened 😅 I've watched a few videos, but everyone's experience is different, so I don't know who to believe. Can anyone here share their experience with this? I want to arrange my flight back reasonably.

Thanks in advance!
