What should I pack for self-care after a beauty trip?

Hi! I'm preparing for my first trip to Korea to try something with my face, and then I'll be quarantined at home for about a week. I'm worried about self-care afterward and what I should pack. Right now, I'm thinking of buying cooling face masks, silicone scar sheets, and some kind of soothing gel. I want my skin to heal quickly and I don't want too much scarring.

Does anyone who's been to Korea know how they took care of themselves and what were the most important things to pack? Do I need to buy Korean brands there, or can I bring them from home? This is making me feel insecure 😅 Thank you so much!
