I went to South Korea for a small project. Do you have any suggestions for products to reduce swelling and for skincare before returning home?

Hi everyone, I'm Juan. I'm planning to go to Seoul next week for a minor cosmetic procedure and then fly directly back home. I've heard there will be some swelling afterward, so I'd like to do some research beforehand. Has anyone experienced this?

My main questions are: Will the swelling be most noticeable in the days leading up to my flight home? What are some ways to help reduce swelling? I plan to bring some cooling compresses and soothing products back with me, but I'm not sure which ones are most effective. Also, what should I be careful about during the flight? For example, should I avoid certain actions or foods?

Furthermore, are similar products used after the procedure (like repair creams and serums) available in China? Or do I have to buy specific brands in Korea? I don't know much about skincare products, so I hope experienced ladies can give me some practical advice. Thank you!
