What do you bring back for your post-trip skincare routine?

Hi everyone! I'm Thao, and I've just planned a trip to Korea for some facial treatments. I'm a bit worried about the aftercare, though. I'll be flying back to Vietnam in about a week, so I'm wondering what I should bring to help with my recovery process.

I'm thinking of buying a few things there, like cooling masks, silicone patches, and soothing gels, but I'm not sure which products are actually helpful or just a waste of money. Has anyone brought these items back in their luggage? Or for those with experience, what's most worth packing in a suitcase? I'm also unsure about what to prioritize.

Really looking forward to hearing from you all! Thanks 💕
