Aftercare items to bring to Korea—what did you bring?

Hi everyone! So I'm planning a trip to Korea next month for a small treatment, and I'm thinking about what I should bring for aftercare. I'm a bit worried about how the recovery will be, especially if I need familiar cooling or soothing products.

I've been googling, and it seems like a lot of people are talking about cooling masks and gels to soothe the skin. Some also mention silicone scar sheets, but I'm not sure if they're really necessary or just optional. Do they prescribe anything special in Korea, or is it better for me to bring a stock from Indonesia?

For those of you who have traveled there, what aftercare items are really useful? Or, conversely, are there any things I don't need to bring much because they're sold there or provided by the clinic? I want to be well-prepared, but not overly so. Appreciate any tips! 🙏
