What do people usually bring for post-treatment care when getting beauty treatments in Korea?

Hello everyone, I'm Ha from Vietnam. I'm about to go to Korea for some treatments and I'm worried about post-treatment skincare. I plan to bring some cooling masks from home, along with a soothing gel to apply. But I'm not sure if I should bring anything else.

For those of you who have had beauty treatments done in Korea, could you share your experiences? What do you usually bring to help with the recovery process? I've heard that cooling masks are great for post-treatment care, but I'm also curious if I need to bring them from home or if I can buy them there.

What about silicone scar sheets? Do you use them? I'm not entirely sure about their effectiveness, so I wanted to ask beforehand. If anyone has experience with them, please help me out! Thank you all so much! 😊
