Packing aftercare products for a beauty trip—what are you bringing?

Hey everyone! So I've booked a treatment in Korea for next month and I'm overthinking what to pack for aftercare. I know treatments can make the skin a bit sensitive and require extra care, but I'm unsure whether to buy things here or purchase them in Korea once I arrive.

I'm thinking of packing cooling masks, silicone scar sheets, and soothing gel—but is there anything else I need? Or has anyone else been through this? Would it be better to buy pre-made cooling products or look for local ones first? I'm worried that if I bring them from Indonesia, they might get damaged or might not be suitable for my treatment.

Thanks so much if anyone can share their experience! I'd also like to know if it's worth bringing a lot or if it's more practical to just buy them there. Appreciate any tips! 💙
