What anti-swelling products should I bring after having minor surgery in South Korea?

Hi everyone! I'm Peiyu, and I'm planning to have a minor procedure in Seoul soon, but I need to travel abroad, so I'll be flying back to Taiwan the day after the surgery. I'm a little worried about swelling and would like to ask if anyone has experience with this?

I'd like to know how long the swelling usually lasts after the procedure, and what anti-swelling products I should bring. Has anyone recommended cooling gels or specific face masks? I'm a bit unsure what I can bring on the plane because of liquid restrictions. Also, does anyone know how many days it's okay to go back to work after the procedure?

If anyone has also traveled abroad for a procedure and immediately flown back, could you share your experience? Especially what skincare products did you bring, or what preparations were made to make recovery smoother? Thank you!
