How should I care for my skin after a minor procedure? Looking for advice and experiences.

Hi everyone! I'm Rong. I had a small procedure done in Seoul the day before yesterday and I'm back at the hotel now. The swelling and bruising are still quite noticeable, and I'm a little worried.

I'd like to ask everyone, how do you usually care for yourselves after similar procedures? What's the order of applying cold and hot compresses? I heard you should apply cold compresses for the first few days, then switch to hot compresses, but I'm still a bit confused about the specifics. Also, are there any dietary restrictions? Should I avoid spicy foods?

Another question is, how long does it usually take for the swelling to go down? I have a work meeting next week, and I'm worried I'll still be swollen then. Has anyone experienced a similar timeline? Of course, I know everyone's recovery speed is different, but I'd like to get some feedback from everyone. Thank you!
