What kind of preparation is needed for swelling care after a minor procedure in Korea?

Hi, this is Sayaka. I'm planning to have a minor procedure done in Korea next month, and I have some questions about aftercare. I've heard that swelling can occur after the procedure, so I want to make sure I take proper precautions before and after returning home.

I'm especially concerned about how to reduce swelling before and after flying. What kind of aftercare products should I bring, like cooling sheets? Is regular skincare sufficient, or do I need any special preparations? I'm not very knowledgeable about this, so I'd appreciate your advice.

For those who have actually had the procedure, what kind of preparations did you make? I'd also like to know if there are any precautions I should take after returning home. I'd be happy to hear about any experiences you have.
