What do people bring back for post-beauty treatment care from Korea?

Hey everyone! I'm Giang, and I'm heading to Korea for a trip soon. I'm planning to get a few minor skin treatments done. I want to prepare beforehand by bringing some of my current skincare products, but I'm not sure which ones to prioritize.

I'm considering bringing cooling masks, silicone sheets for scar recovery, and soothing gels. But I'm really unsure which ones are truly necessary, or if it would be better to buy them there since they have a wider selection? Has anyone been through this before? What products made you feel most comfortable afterward?

Thanks in advance, ladies! I want to be as prepared as possible for a smooth trip 😊
