How long does it take to recover after getting a nose filler injection before flying home?

Hi everyone! My name is Vy, and I'm planning to try nose fillers while traveling to South Korea next month. However, I'm not entirely sure about the recovery time and I'm worried about prolonged swelling or bruising. I plan to fly back to Vietnam in about 5-7 days; I'm not sure if that's enough time.

Has anyone had fillers in South Korea before and has any experiences they'd like to share? I've heard that it's not like surgery, so recovery is faster, but I still want to know how long it actually takes for the swelling to go away, and whether I should have any insurance. Are there any special things I need to avoid before or after the injection?

Thank you everyone! I'm very curious and a little worried, so I'd appreciate any advice from those with similar experiences.
