What do you bring for post-beauty treatment care in Korea?

Hi everyone! I'm Hong, and I'm about to take a trip to South Korea for some minor procedures. I'm currently trying to figure out what skincare products to bring for post-procedure care. I've heard a lot about choosing the right recovery products, but I'm unsure whether to bring items from Vietnam or buy them there. Although the doctors will provide guidance, I prefer to have some familiar items ready.

Has anyone brought their favorite cooling masks or soothing gels? I've heard that cold masks are great for the initial recovery days, but I'm not sure which type to choose. Also, I'm considering silicone scar sheets just in case they're needed later on – have any of you used any that you found effective?

I'd also like to ask how long in advance people usually prepare to buy the necessary items. Any advice would be greatly appreciated! Thank you so much 💚
