Hello! I'm planning a trip to Korea next month for some aesthetic procedures and I think I need to pack some post-treatment care items. But right now, I'm confused about what to pack. Can anyone who's been before recommend anything truly useful?

I was thinking cooling masks or cold patches might be good, but I'm not sure which kind to buy or where to get them. Has anyone brought items like these with them, or should we buy them after arriving in Korea? I'm also wondering about cooling gel sheets or creams for reducing inflammation – do they really help?

Honestly, I'm also concerned about post-treatment care after I get back. I'd love to hear from anyone willing to share their experiences or tips on choosing care products. Please, any recommendations would be greatly appreciated. Thank you so much!
