Aftercare preparations for a beauty trip to Korea - what did you bring?

Hi everyone! I'm Ratna, planning to go to Korea next month for some treatments. I've consulted with several places, and they say the first week is the most important recovery phase. So, I wanted to ask those of you who have already been—what aftercare items are worth bringing from here or buying there?

I've looked at several options online, like cooling masks, silicone scar sheets, and various soothing gels. But honestly, I'm confused about which ones are truly useful and which ones are just marketing gimmicks. Does anyone recommend bringing them from Indonesia, or is it better to buy them directly in Korea? Budget-wise, I'm still unsure about aftercare.

Also, do I really need to bring everything, or just a few? I'm afraid of over-preparing, but I also want to ensure my skin recovers properly. How do you handle the recovery period the first time around? Any tips or must-haves? Thanks in advance! 💕
