What should I bring back home after micro-needling? Has anyone shared their swelling reduction care tips?

Hello everyone, I'm Huiwen from Taiwan. I'm recently considering getting a minor procedure done in Korea. Since I'll be doing it during a business trip, I have to fly back to Taipei the very next day. I'm a bit worried about swelling and wanted to ask if anyone has experienced a similar situation.

I'd like to know what everyone usually packs in their luggage for swelling reduction or post-procedure care? Things like ice packs, ointments, or moisturizing products, perhaps? I'm not really sure how to take care of myself after the procedure to help the swelling go down quickly. Also, will flying make my face swell up more? Can anyone share their experiences?

Additionally, I'm wondering if there are any common skincare products at Korean drugstores that are particularly suitable for post-procedure care. However, I don't want to buy things randomly, as I'm not sure if they'll suit my skin. If any of you have had similar minor procedures done here, could you offer some advice? Thank you!
