Things to consider when returning home after a minor procedure at the clinic

Hello friends! I'm going to Seoul soon for a minor cosmetic procedure and need to return immediately afterward. I've heard there will be a lot of influence or psychological effects. Are there any good skincare products to reduce swelling that I should bring with me? What kind of materials or products would be very helpful? What do you think the waiting time will be?

Also, are there any issues with swelling resistance? I keep forgetting things I've waited for due to my injury. Has anyone used a good partner for post-procedure care? Please share with everyone! Thank you!
