Intended to go to Korea for a petit procedure but unsure what to prepare for post-procedure care 😅

Hello! My name is Tukta, and I'm planning my first trip to Korea for a small petit procedure. I'll be flying back home the very next day. I wanted to ask if anyone has experience with how much swelling or redness is typical?

I was thinking of preparing some cold packs and a few products to bring back with me, but I'm not sure what kind of aftercare products would be suitable for flying and safe to put in my carry-on. Can anyone offer recommendations? Also, will the clinic provide anything, or do I need to purchase these items myself?

Another thing, for initial swelling care, are there any good tips if I have to be on a plane for a long time? Is there anything that can make me feel more comfortable? Thanks in advance! 🙏
