What aftercare items should you pack for a beauty trip to Korea?

Hello everyone! I'm Bella from Indonesia, and I'm planning a trip to Korea next month for beauty treatments. I've already researched a few procedures I want to try, but what makes me nervous is the recovery phase. I've heard it's really important to have the right skincare after a treatment, especially for calming sensitive skin.

I'm wondering what items I should bring from here or buy in Korea. Does anyone recommend good cooling masks? Or scar silicone sheets if I need them later? Honestly, I've never used products like these before, so I'm a bit confused about what would be suitable for my skin.

For those who have recovered from treatments in Korea, what essential items did you bring or buy? Is it better to buy in Korea or bring from Indonesia? I'm also curious about how long it usually takes for skin to return to normal and be safe for daily activities. Thanks in advance! 🙏
