How should I care for myself after a minor surgery in South Korea? Can anyone share their experience in caring for swelling?

Hi everyone! I'm Wanzi, from Taiwan. I'm considering getting a minor cosmetic procedure in Korea, but I'm worried about swelling on the way back. Could anyone share their experience with aftercare in the first few days after the procedure? Especially how to control swelling, and do I need to bring any special aftercare products?

I was thinking of buying them locally, but I'm not sure if I'll buy the wrong ones if I can't read Korean labels. Does anyone know what ingredients or products generally help with swelling? For example, cooling compresses, soothing masks, etc.? I'm wondering if I should prepare everything in Taiwan beforehand, or do hospitals there usually provide specific aftercare recommendations?

Also, if I'm flying back to Taiwan, what precautions should I take during the swelling period? Has anyone experienced this? Thanks for any advice!
