I'd like to ask, I'm visiting for K-beauty and need to take care of myself. What has everyone brought?

Hello, my name is Pim. I'm planning a trip to Korea for fun and to get some beauty treatments. However, I'm not too sure about post-treatment care 😅. Has anyone who's been before brought any aftercare items, like cooling masks, silicone sheets, or gel patches? Things that are available in Thailand, so I don't have to buy them in Korea, but are still effective.

I'm a bit worried about what I need to prepare for when I get back. Can anyone recommend what's truly worth it and easy to use? Has anyone mentioned what kind of care is suitable for the treated areas? I'm afraid I might not do it the right way and make the problem worse.

Would anyone like to share their experiences? 🙏 What did you bring, or what kind of items are good? I'm all ears. Thank you.
