On your way back from your beauty trip, what kind of aftercare products did everyone bring?

Hello, it's Hana! I just got back from Korea last week, and I have a question about post-treatment care products.

This time, I brought a cooling mask and silicone sheets with me, but I realized they sell a lot of things locally too. I heard that cooling is important right after treatment and during the flight home, so I thought a cooling mask was essential. But in reality, what kind of aftercare products do people usually bring from Japan or get locally?

I'm particularly curious if the necessary items change depending on the type of treatment. Also, I wonder how everyone handles care during long travel back home. Has anyone brought calming gels? Honestly, I'd love to hear from experienced people about what to prioritize bringing.

If you're willing, please share your recommended aftercare routines!
