What swelling relief products should I bring before my trip after a minor surgery?

Hi everyone, I'm Yi-xuan from Taiwan. I've been thinking about getting a minor procedure done recently, but the timing is a bit tricky – I'm planning an international trip in a month and I'm worried about potential swelling.

I'd like to ask those of you with experience, how long does swelling typically last after a minor surgery? I'm still not entirely sure which procedure I'll go for, but it probably won't be anything too complex. If there's still swelling, do you have any recommendations for products to bring on the plane or use at the hotel? I've heard that cold compresses or certain masks might help, but I'm not sure if they're actually effective.

Also, I'm curious about how you all plan your treatment timing before traveling abroad. Are there any specific things to pay attention to? Thanks in advance for your advice!
