What aftercare items did you bring back from your beauty trip?

Hi, this is Emi. I had a procedure done in Korea last month, and I'm worried about aftercare. I'm wondering whether to buy cooling masks, soothing gels, and silicone sheets there, but what do you all actually bring back?

It seems like they give you some things right after the procedure, but I'm worried about aftercare for the first few days after returning home... I'm especially unsure whether I should use the cooling mask every day, or if it's enough for just the first few days. Also, are there any differences between what you can buy in Japan and what you can buy in Korea?

I think there are quite a few people who get procedures done while traveling, so I'd love to hear what aftercare items you prepared. Any personal experiences would be very helpful.
