Ladies, for my first beauty trip to Korea, I want to be well-prepared for my post-trip self-care routine, but I'm unsure what to pack. For those of you who have been before, can you recommend whether to bring cooling masks or silicone scar sheets?

I've seen people suggest bringing various wound care products (soothing gels, different types of face masks) and others say they can be found in Korea at better prices. I'm confused whether I should buy them there or bring them from home? And also, if I bring them, will they be heavy for travel?

Please share your recommendations on what you've brought that was truly useful. I'm looking for advice from ladies who have already been!
