Beauty Trip Essentials: What Did Everyone Pack?

Hi everyone! I'm about to go to Korea for a minor cosmetic procedure and I'm currently struggling with how to prepare my post-care products. I've heard that the care during the first few days after the procedure is really crucial, but I'm not quite sure what kind of products I should bring.

I'm wondering if I should buy some cooling masks and soothing gels from home first, or if it would be more convenient to buy them after I get to Korea. Also, what about silicone scar sheets? Has anyone used them? I feel a bit lost on where to start. I'd like to ask everyone what kind of post-care products you prepared when you went for procedures before. Did you buy them in your home country and bring them with you, or did you purchase them locally? I'm also not sure how to plan my budget.

It would be great if anyone could share their experiences! I'm especially interested in knowing which items were actually useful and which ones might not have been. Thanks everyone!
