Aftercare prep for a beauty trip—what do you pack?

Hi everyone! I'm preparing for a trip to Korea next month and plan to try a few treatments. I'm a bit nervous about the recovery phase, especially if I have to fly home when my skin is still sensitive.

I wanted to ask, for those of you who have been, what do you bring from home for aftercare? I'm considering cooling masks, silicone scar sheets, and soothing gels. Should I buy them before I leave, or is it better to look for them locally? Or do you have any recommendations for specific items that are really worth it?

An additional question—how long is your recovery period usually before you can board a plane or return to your normal routine? I want to make sure I schedule it smartly so I don't get stressed out by the trip. Thanks in advance! I'd love to hear your experiences. 💙
