Going back to the US after a procedure—what should I pack for aftercare?

Hey everyone! So I'm planning to get a minor procedure done while I'm visiting Korea, but I'm flying back to the States about a week after. I'm trying to figure out what I should bring with me to manage swelling and keep up with aftercare on the flight and at home. Has anyone traveled after getting something done here? I'm a little nervous about flying with potential swelling, honestly.

I'm thinking about packing things like ice packs, compression products, and maybe some gentle skincare stuff, but I'm not totally sure what actually helps or what's even allowed in luggage. Also, are there specific product types (like serums or masks) that people generally recommend for aftercare recovery, or does it depend a lot on what procedure you get? I don't want to overpack but also don't want to be unprepared.

Any tips on managing the flight itself, or things you wish you'd brought? Thanks in advance!
