How long is the recovery after nose filler before flying home?

Hello everyone! I'm Nur from Indonesia. So, I'm thinking about trying nose fillers when I go to Korea next month, but I can only stay for 10 days. I'd love to know from those of you who have done it, how long is the downtime usually?

I'm a bit worried because I have to take a flight home. Can I fly immediately after the treatment, or do I need to wait a few days? I've heard about swelling and redness, but it's unclear how long it lasts. Has anyone experienced this or can share their experience?

Also, would it be better to get the treatment at the beginning or end of my vacation? Hehe, sorry for so many questions, it's my first time so I'm a bit nervous. Thanks to everyone who's willing to share!
