I had a small procedure done before going abroad, how should I pack my post-care products?

Hi everyone, I'm considering getting a small procedure done before I go abroad, but I'm worried about post-operative care. I've heard that post-surgery swelling management is really important, but I'll be traveling for two weeks. Is there anything I should pack?

Mainly, I want to ask if anyone has experienced flying after surgery. Will sitting on a plane during the swelling period worsen it? I plan to bring some basic soothing masks and hydrating products, but I'm not sure what kind of products would be most suitable. Can anyone share their experiences, like what care items they brought and how effective they were? Or is post-operative care mainly dependent on doctor's orders and time?

Also, I'd like to know where these recovery products are generally available. Are there similar options in China? I'm a bit afraid of choosing the wrong products and actually burdening my skin more. Can any of you offer some general advice?
