Non-surgical nasal flap - recovery time before flying home?

Hi ladies, my name is Tuyen from Vietnam. I'm planning to get a nose filler treatment while traveling to Korea next month, but I'm worried about the recovery process. I'll only be there for about 5-7 days, so I'm afraid of the swelling or hardening of the skin when I get back to Vietnam.

Has anyone had this procedure done before? I'd like to know how long it usually takes for the swelling to go away. I heard it's non-surgical, so it might be faster, but I don't know exactly how many days it takes to look normal again. Or should I wait a few more days or three weeks for it to be safer?

I'd appreciate it if you could share your experiences! Thanks in advance.
