Looking for recommendations for aftercare items to bring to Korea, any suggestions?

Hello everyone! I'm Ayu, and I'm planning a trip to Korea next month for some minor treatments. I want to prepare with good aftercare products. I already have a list from my initial consultation, but I'm still unsure about which products I should buy here or there.

Right now, I'm wondering if it's better to bring cooling masks, silicone scar sheets, and soothing gel from Indonesia, or to buy them directly in Korea. I'm worried about carrying heavy items and also curious about what people typically use after treatments there. Are there any more recommended options?

For those of you who have experienced this, what products did you bring or end up buying there? Do you think investing in good aftercare skincare is worth it? After my treatment, I just want my skin to recover well, hehe. Thanks so much to anyone who shares tips!
