I'm going to South Korea for cosmetic treatments for the first time. During my trip, I'm planning to get facial care, among other things. I'm wondering what kind of post-treatment products I should bring.

I've heard that people usually bring cold packs, silicone scar sheets, or seaweed gel. I'm not sure which of these would be most valuable for my situation. Since I have limited recovery time due to my travel schedule, how should I prepare in advance? Did you bring your own supplies, or did you purchase them there? I feel like some items might have issues with air travel.

This seems like a good question for those who are unsure about exactly what type of post-treatment products to bring. I'm seeking advice from those with experience!
