Consultation regarding travel after a minor procedure: swelling countermeasures and aftercare products

Hello everyone, Hana here. I'm planning to get a minor procedure in Korea next month, but I have to travel to another country immediately afterward, and honestly, I'm a little anxious. I'm wondering if anyone with experience could tell me how long swelling typically lasts and what kind of aftercare products I should bring.

I'm particularly interested in cooling items I can use while traveling, or moisturizing products that can be applied over makeup... How did you manage on planes or in hotels? Also, I'd like to know if I can buy alternatives at pharmacies if I suddenly need something while I'm there.

I know swelling can vary depending on the type of procedure and individual differences, so I'd be happy to hear any tips you have, even if it's just general advice. Since canceling my trip entirely isn't really an option, I'm looking forward to any practical advice you can offer!
