What aftercare essentials do you pack for your beauty trips to Korea?

Hi everyone! I'm Wati, and I have a question for those of you who have been to Korea for beauty treatments. I'm planning to go next month and want to prepare thoroughly for aftercare.

So, I'd like to know, based on your experiences, what skincare or aftercare products are most worth bringing from home? I've heard many people bring their own cooling masks, and some swear by specific silicone scar sheets or soothing gels. But I'm a bit confused about what's truly essential and what can actually be bought there as well.

Since I'm worried about overpacking, I want to be efficient but also don't want to be short on anything. What do you usually pack? Have you found any good products in Korea that were really helpful, or is it generally more convenient to bring your own from here? Please share your experiences! Thanks in advance 💕
