What aftercare items to bring on a beauty trip to Korea—what do you recommend?

Hi everyone! So I'm planning to go to Korea next month and want to try some beauty treatments while I'm there. I've read a lot about the importance of aftercare, but I'm a bit confused about what items I should bring from Indonesia versus buying there.

I'm thinking of bringing a cooling mask, silicone scar sheets, and soothing gel for the recovery process. But I'm not sure if it's more practical to just buy everything in Korea or bring it from here? I'm worried about it being a bit heavy in my suitcase.

For those of you who have been to Korea and had treatments, what aftercare items do you feel are most important to bring or focus on during recovery? Is there anything you regret not bringing or bringing that you didn't really need?

Your suggestions are very helpful! Thank you in advance! 💕
