What products did you all bring for post-beauty trip skincare?

Hi everyone! I'm planning a small beauty treatment in Korea soon and want to get my skincare routine done before I go back home. I'm wondering which over-the-counter skincare products I should bring back, in case I can't find suitable items during the recovery period.

I've heard that cooling masks, silicone scar patches, and soothing gels are pretty good, but I'm not sure which ones are the most practical, or if there are any other products I might have missed. Have any of you been particularly reliant on certain skincare products after your treatments in Korea? How did you manage your routines?

I'd like to know about your experiences—what really helped you, and what might have been unnecessary. If you have any recommendations for product categories (not necessarily specific brands), or ideas on how to prepare a skincare checklist, I'd love to hear them! Thank you!
