Post-Beauty Journey Aftercare: What products did everyone bring?

Hi everyone! I'm planning a trip to Korea for some beauty treatments and I'm currently thinking about what skincare products to bring. I've heard that the first few days of post-procedure care are really important, but I'm a bit unsure about what exactly I need to prepare.

I was wondering if I should bring things like cooling masks or silicone scar sheets from home beforehand? Or would it be better to buy them locally in Korea? Has anyone had a similar experience? I'm especially interested in hearing about any soothing gels or cooling products you've used and how they felt post-procedure. I know it definitely depends on individual skin reactions, but I'd like to get a sense of everyone's experiences first.

If you have any must-have skincare product lists or little tips, please feel free to share! For example, what types of products are most useful, or what pitfalls should I avoid. Thanks!
