What are some good post-travel skincare products to use after a trip to Korea? Any recommendations?

I'm planning a trip to Korea for beauty treatments and I'm wondering what to pack for post-treatment care. I'm worried it might be harder to find familiar items there, and I'm not sure what to choose if I buy them locally. 😅

I'm thinking of bringing cooling face masks, silicone scar sheets, and gels for sensitive skin. Some people have recommended these to help with recovery, but I'm not sure what to pack, or if some things I think are essential might actually be unnecessary. 🤔

Has anyone traveled to Korea for treatments before? What did you bring, or are you sure it's better to buy things there? Any tips from those who have been through this?
