What skincare products do you bring back after completing a project in Korea?

Hi everyone! I came to Korea specifically for a small procedure and am currently in the recovery period. I did my research beforehand and brought some cooling face masks and soothing gels from China, but to be honest, I'm still a little unsure if that's enough.

I wanted to ask everyone, what kind of skincare products do you usually buy during your recovery period after a procedure in Korea? For example, cooling face masks, silicone scar patches, and repair serums? Can I buy them at convenience stores, or do I need to go to a specialty store? I'm a little worried that my choices might be incorrect, since different procedures may require different care.

If you've used any products that you found effective, could you share the brand or where to buy them? They don't have to be particularly expensive; I'm just looking for something that genuinely helps and feels comfortable to use. Thank you all!
