How should I care for my skin after getting a facial injection? Looking for advice and experiences.

Hi everyone, this is Xinyi. I had a minor beauty treatment in Seoul a couple of days ago, and my face is still a bit swollen and bruised, which worries me. I'd like to ask everyone, how did you take care of your faces after similar treatments? Especially regarding reducing swelling and bruising, what reliable daily care methods are there?

Right now, I'm just applying cold compresses, drinking plenty of water, and trying to move around as little as possible, but I'm not sure if there's anything else I should be careful about. I've heard that diet is also important, but I'm not sure what to avoid specifically. Also, should I use extra gentle skincare products? I'm a little worried that using the wrong ones might worsen the swelling.

Could any of you share your recovery experience? I'd especially like to hear about the most crucial care steps I took in the first few days. Thank you!
