For those flying to Korea for treatments, what at-home skincare products are you bringing?

Hi everyone! I'm Shihhan, and I'm heading to Korea next month for a treatment. I wanted to ask what products everyone usually brings for their recovery period.

I'm a bit unsure about how to prepare right now. I know post-treatment care is important, but bringing too much luggage isn't very practical. I was thinking of bringing things like cold packs and silicone scar sheets, or would it be more convenient to buy them locally? Has anyone used soothing gels? How effective are they?

Also, I'm wondering how much I should prepare to last the entire recovery period. Or would it be more cost-effective to just buy ready-made skincare products there? If anyone has had a treatment in Korea before, could you share what you brought? I really need some advice from those who have done this before!
