After undergoing minor surgery in Korea, how should I care for myself on the way back to Taiwan?

Hi everyone! I'm Chiawei, and I've been thinking about getting a small procedure done in Korea recently. However, I'm a bit worried about how to take care of my skin during the flight back to Taiwan. I've heard there can be swelling after the procedure, and I'm concerned that sitting on a plane for so long might make it worse?

I'd love to ask for advice from those of you who have experience. What products do you usually bring back to care for your skin? For example, ice packs, anti-swelling serums, or any hydrating masks? I'm not sure if I can bring frozen items on the plane, or if there are any alternatives.

Also, what are the most important post-procedure care steps for the first few days? I know I need to avoid water and use cold compresses, but I'm not quite clear on the specific order and product combinations. Can anyone share their experiences? Thanks!
