What at-home recovery aftercare items do you bring after a treatment?

Hi everyone! So I'm planning a trip to Korea next month and really want to try a few minor treatments there. What's making me overthink is the recovery part, since I'll be flying back to Indonesia in a few days. I want to prepare myself well so I don't get stressed.

I've started listing aftercare items I might need to bring—like cooling masks, soothing sheet masks, maybe even silicone scar sheets if necessary. But I've never experienced this before, so honestly, I'm a bit confused about which items are truly essential and which are just optional. Plus, luggage space is limited.

Has anyone been through this before? What aftercare items do you think are absolutely necessary, and which aren't really worth it? Also—would it be better for me to buy them here before I leave, or buy them directly in Korea because the prices might be more affordable? Appreciate any tips! 🙏
