What do you bring back to use for post-treatment care after beauty treatments in Korea?

My name is My, and this is my first time flying to Korea for some beauty treatments. I'm worried about the aftercare because I'll be there for about 1-2 weeks. I'm trying to figure out what to bring from home to support the recovery process – although I know there are many good skincare products there.

I'm wondering if I should bring cooling masks, silicone scar patches, or soothing gels from home? Or should I buy these in Korea? I'm not sure what to prioritize, and which ones are really helpful. Have you guys been on a similar trip? What did you bring and did it help?

I know everyone has different skin, so I just want to hear your personal experiences. Thanks in advance!
