What are the best beauty products you bring with you after your beauty vacation?

Hi girls! I'm Rana from the UAE and I've decided to go to Korea next month for some beauty treatments. It's my first time traveling specifically for beauty treatments and I'm not sure exactly what I need to bring for aftercare. I've heard that people bring certain cooling and soothing products for after the procedures.

Have any of you brought cooling masks or soothing gels? What are the best options you recommend? Some people have also told me about silicone sheets for scars... are these necessary or optional? I'm not sure whether to bring them here or buy them there.

Honestly, I'm a little worried about the aftercare part and I don't know how to prepare properly. For those of you who have gone through this before, what's your advice? Do I really need to bring everything here or are there plenty of options available in Korea?
