What post-treatment care products did everyone bring on their beauty trip?

Hi everyone! I'm planning to go to Korea next month for a minor cosmetic procedure and am starting to think about post-treatment care. I'm wondering if I should bring some cooling masks and silicone scar patches from China beforehand, so I can use them during recovery. However, I'm not entirely sure what I'll need, and I'm worried about bringing too much and making it too heavy.

Has anyone had a similar procedure before? What care products did you bring? I've heard that Korean drugstores have many of these products, but I'm still a little hesitant to choose them myself, afraid of buying the wrong ones. Are cooling masks and soothing gels absolutely necessary? Or are silicone scar patches the main focus?

I hope someone can share their experience! Also, if I buy these locally, how much budget should I prepare? I want to be well-prepared so I'll feel more confident during recovery. Thank you everyone!
