How much downtime is there for nose fillers?

Hello, it's Misaki. I'm thinking about getting some minor cosmetic procedures in Korea, and I have a question about nose fillers.

I'm planning a trip to Korea soon, and if I decide to get fillers, I was thinking of doing it during my stay. However, I'll only have a few days before returning to my home country, so I'm worried about the downtime... How long does swelling and redness typically last?

Also, can I go about my day as usual right after the procedure? And are there any precautions I should take before boarding a plane? If anyone has experience with this, I'd love to hear your thoughts!
