How long after getting nasal fillers can I fly?

Hi everyone, I'm Qing. I'm recently considering getting a nose filler in Seoul, but my vacation time is a bit tight. I'd like to ask everyone, if I get a non-surgical nose filler, how long does it usually take before I can fly back home?

I've seen conflicting information online; some say a few days, others say one or two weeks. My main concern is whether the air pressure changes during the flight will affect the results immediately after the procedure, or whether it will increase swelling. Has anyone had this procedure done and flown home shortly after? What was your experience like?

Also, how many days should I allow beforehand to be on the safe side? I'm still figuring out my schedule, so I'd appreciate any advice. Thank you!
