After returning from abroad from a small procedure, how should I care for it? Experienced sisters, let's chat!

Hello everyone, I'm Rong. I'd like to ask for your advice: if I have a minor procedure done in Korea (like a skin treatment) and then need to travel abroad, how should I manage swelling and recovery? I've heard there might be some swelling in the first few days, but I don't have much experience.

I'm wondering what products everyone usually brings back home for aftercare. For example, soothing masks, items for cold compresses, or are there any specific things I should pay attention to? I'm a bit worried that flying might worsen the swelling.

Also, I'd like to ask everyone, how long does it usually take to look mostly recovered? I know it varies from person to person, but I just want to be mentally prepared. If any of you have had similar minor procedures and then traveled abroad, could you please share your experiences? Thank you all!
