Beauty trip essentials! What post-procedure care products did everyone pack?

Hi everyone! I'm planning to get a small cosmetic procedure done in Korea next month and want to take good care of myself while I'm there. I was wondering if I should bring some post-procedure care items from home to feel more at ease.

Right now, I'm debating whether to bring cold compress masks, silicone scar sheets, and soothing gels. I've heard some people prepare these in advance, but I'm not sure if they're easily available in Korea or if they'll be particularly expensive. Have any of you had similar procedures done in Korea before? Could you share what you prepared? I'm especially curious about which products were genuinely helpful post-procedure.

Also, if I were to buy them locally in Korea, do you have any recommendations? I'm worried it might be a hassle to scramble for things I might need right after the procedure. All suggestions are welcome!
