Does anyone have experience with swelling reduction and aftercare following a minor surgery in South Korea?

Hi everyone! I'm Chiawei from Taiwan. I'm planning to have a minor cosmetic procedure in Korea, but I'm a little worried about post-operative swelling and aftercare. Since I'm going on a business trip, I won't be staying in Korea for long, so I'd like to ask if the first few days after the procedure are the most important for reducing swelling?

I'd like to know if anyone has had a similar procedure in Korea, and how long does the swelling usually last? Also, what aftercare products do you bring? Do you bring them from Taiwan or buy them locally? I'm a little unsure what to prepare.

If anyone has experience to share, that would be so helpful! Like, are there any recommended ice pack methods, or what kind of aftercare steps are most helpful for reducing swelling? I want the swelling to subside as much as possible before returning to Taiwan, otherwise it'll be a bit embarrassing at work (laughs). Thank you everyone!
