Has anyone packed anything for post-treatment care for their trip to Korea?

Hello, my name is Aon. I'm planning a trip to Korea and was thinking of trying some beauty treatments there, but I'm a bit clueless about post-treatment care 🙈.

So, I wanted to ask if anyone has packed anything for self-care, like cooling masks or gel sheets? I've seen people talk about training and reducing redness after procedures, and I'm wondering what I should get. I really want my skin to recover quickly.

Does anyone have any experience? Please guide me! For example, is there anything you packed that you found genuinely helpful, or anything you think I should buy while I'm there? Simple things that make a big difference. Any advice would be greatly appreciated! 💕
