What to bring when traveling abroad after minor surgery? Questions about swelling reduction and aftercare.

Hi everyone, I'm Wen. I'm planning to have a minor cosmetic procedure next month, but I'll be going on a business trip abroad almost immediately after the surgery, and the swelling will last for about a week. I'd like to ask experienced women what kind of aftercare products you brought on your trips, especially for reducing swelling? What products were effective?

I've heard that cold compresses are important, but how do I bring cold compresses on a plane? Also, are liquids like ointments or serums allowed on airplanes? I'm a little worried about security checks. Are there any special post-operative skincare precautions? Or is it enough to just use a gentle cleanser and moisturizer?

Another question: if I need to see people during the post-operative swelling period, how do you usually handle it? Are there any skincare products or tips that can help reduce the appearance of swelling? I know it takes time, but I always want to be mentally prepared. Has anyone experienced something similar? Looking forward to hearing your experiences!
