Question: After getting a nose filler injection, how long do I have to wait before I can fly back home?

Has anyone here had a nose filler treatment in Korea? I'm planning to go there to try it, but I'm worried about the recovery time because my flight back to Vietnam is coming up soon. I want to know how long it usually takes to safely fly after a non-surgical nose filler treatment without worrying about swelling or complications?

I've heard that this type of non-surgical treatment has a relatively quick recovery, but I'm not very sure about the specifics. Has anyone experienced this before? How many days does it usually take for the swelling to go down and for me to be able to fly? I'm considering whether to have it done before or after my flight.

Thanks for your help!
