Tips for managing swelling + aftercare on the flight home?

Hey everyone! I'm planning to get a small procedure done while I'm in Korea next month, and I'm flying back to the US like 5 days after. I know swelling is pretty normal, but I'm honestly a bit nervous about sitting on a plane with a puffy face lol. Does anyone have tips for managing swelling in those first few days? Like, should I be bringing specific products from home or are there good things to pick up here?

Also, what kind of aftercare stuff should I pack in my carry-on? I'm thinking things like gentle cleansers and moisturizers, but I'm not even sure what brands are best or what I actually *need*. I've heard ice packs help but I'm not sure about traveling with those. Has anyone done this before and what did you wish you'd brought with you?

Thanks in advance! Any general advice would be really helpful 💙
