How should I take care of myself to reduce swelling after a minor cosmetic procedure and then travel abroad?

Hi everyone, I'm Yun. I'm planning to get a small injection treatment next month, but I have to go on a business trip abroad for a week afterward, so I'm a little worried. I've heard there will be swelling during the recovery period, and I'd like to ask if anyone has experienced this?

I mainly want to know what practical methods are available for reducing swelling after the procedure? Besides ice packs, what else should I do? Also, what skincare products should I bring when traveling abroad? I know my skin will be more sensitive after the procedure, and I don't want any problems on the plane or in a foreign country.

Additionally, I'd like to ask if anyone has traveled abroad shortly after the procedure? Are there any special precautions I need to take? For example, sun protection and moisturizing—should I adjust these according to different climates? I'm not very familiar with the whole process yet, so I'd like to hear everyone's real experiences. Thank you!
