Hello, Erika here! I recently had some cosmetic procedures done in Korea last month, and I have a question about post-treatment care. I heard that it's really important to keep the treated area cool and calm for a few days afterward, so I came back with a bunch of items.

What kind of cooling masks, silicone sheets, or soothing gels do you all choose to bring back with you from Korea? Honestly, there are so many options, I'm not sure which ones are truly effective... Are there any specific things you've used during the first week after returning home that you felt made a real difference?

Also, I'd love to hear about practical tips, like what's easy to use once you're back in Japan, or what comes in a travel-friendly size. I'm looking forward to advice from those of you who have experience!
