Do you have any tips for reducing swelling after a short treatment?

Hi everyone! I'm Jiaqi, from Taiwan. I had a short treatment in Seoul a few days ago, and my face is still a bit swollen and bruised. I was wondering if anyone has any experiences to share. I know these are normal reactions, but I'd still like to know how you all take care of yourselves.

Currently, I'm just applying ice, drinking lots of water, and trying to elevate my head while sleeping, but I'm not sure if there's anything else I can do. I've heard that some people use specific skincare products to help reduce swelling or adjust their diet, but I don't really know which ones actually help. Would anyone be willing to share their recovery process? How long did it take for the swelling to completely subside?

Also, besides physical care, is a positive mindset also important? I'm a little worried that I'll look a bit strange during this recovery period, but I know it's only temporary. If anyone has experienced something similar, I'd love to hear your stories! Thank you everyone!
