I'm going to return after a minor procedure - what should I bring to reduce swelling?

Hello, my name is Uyang. I am going to Seoul soon to have a minor cosmetic procedure. I plan to return to my country in a few days after the procedure, so I would like to know what products I should bring to properly treat my recent acne and inflammation. What products do people who have gone to cosmetic surgeons like you use in their experience? What kind of things do you usually do, such as removing the pimples with a cloth? Please give me some suggestions on products that would be good to take with you on the road to treat acne. Thank you!
