How do I take care of my skin after a minor procedure? Any ladies have any tips to share?

Hi everyone, I'm Ting. I had a minor beauty treatment in Seoul a couple of days ago, and my face is still a bit swollen and bruised. I regret not asking for advice beforehand. I'd like to ask everyone, what's the best way to care for my face at this stage? What should I be careful about?

Currently, I'm mainly using ice packs and trying to elevate my head while sleeping, but I'm not sure if that's the right approach. Have any of you had similar treatments and could share your recovery process? For example, when does the swelling subside, and how long does it take for the bruising to fade? I've heard that diet and lifestyle are also important, but I'm still a bit confused about the specifics.

Also, I'd like to ask what things I should avoid during the recovery period, and what special precautions I should take? I would be so grateful if any of you could share your skincare tips!
