I have a question. How many days do I have to wait after getting nose fillers before I can fly back?

Hi! I'm thinking of going to Korea for non-surgical nose filler treatment, but I have questions about recovery. I'll be in Korea for about 5-6 days before flying home.

For those who have had this done, I'd appreciate your experience. What is the typical level of redness, swelling, or noticeable marks from the first day until later? And how many days does it take to recover enough to fly without worrying about changes in air pressure? I'm not sure if I'll have enough time. 😅

Please share your experience. Thank you in advance!
