Tips for managing swelling and aftercare products for travel after minor procedures

Hi everyone! So, my plan is to try a minor procedure in Korea next month, but unfortunately, I have to fly back home 2-3 days afterward. I'm really panicking about swelling and how to manage post-treatment care on the plane and then at home. Has anyone traveled after a procedure like this?

What I'd like to know: how long does the swelling usually last? Are there any good products to bring in a bag for aftercare? I've heard about cooling masks or serums, but I'm unsure which ones are worth bringing home. Also, does anyone know the best way to manage all this on the plane?

I also want to ask about skincare routines during the recovery period. Is it better to keep it simple, or are there specific steps that are really helpful? And if my face is still swollen when I get home, how do I explain it to my family, hahaha 😅

Thank you so much to anyone who wants to share tips or experiences! Super appreciate it!
