How long after getting nasal fillers can I fly on an airplane?

Hi, my name is Haruka. I'm planning to go to Korea next month for cosmetic procedures, and I have a question about nasal fillers.

How long does it usually take for the downtime to subside after a non-surgical nasal filler procedure? I'm actually scheduled to return to Japan in 5 days, and I have to take a plane before then. I'm worried about noticeable changes like swelling and bruising...

If anyone has experience with this, I would be very grateful if you could tell me what it was like. I know there are individual differences, but I'd like to know a general guideline. Also, if there are any precautions I should take immediately after the procedure, I'd like to know beforehand! Thank you in advance.
