For post-procedure swelling care... are there any items I should bring with me when traveling?

Hi, this is Honoka. I'm planning to get a minor cosmetic procedure in Korea soon, but I have a trip planned right afterward, so I'd like to ask for advice on swelling prevention.

I understand that swelling can occur after a procedure, but are there any self-care measures I can take before boarding a plane or during travel? Like applying a cold compress or something to scrub...? Also, what kind of aftercare products should I pack that I can easily carry with me?

If anyone has experience with this, I'd love to hear what you actually brought and how you managed the swelling. I'm sure the doctor will give me instructions, but any general tips would be greatly appreciated. I want to enjoy my trip, so I'd like to minimize the swelling if possible...😅
