Please tell me about swelling care after facial contouring treatments and what products I should bring when traveling.

Hello, this is Mizuki. I'm planning to get a facial contouring procedure in Korea next month, but I have to travel to another country immediately afterward... I'd like to ask about swelling management after the procedure.

About how long does the peak swelling usually last? Also, I'd like to know if there are any convenient products for swelling care during airplane travel or afterward. Are there any portable items like cooling sheets?

If anyone has experience with getting procedures around their travel dates, I'd love to hear what you actually brought with you and what kind of care you did. Also, are there any precautions I should take...? I'm a bit anxious, so I'd like to hear from people who have had similar experiences. Thank you in advance!
