How should I care for myself after a minor treatment? Looking for advice and experiences!

Hi ladies! I had a minor skin treatment in Seoul a couple of days ago, and my face is a bit swollen and bruised now, which worries me. Although the doctor gave me some basic care instructions, I'd like to hear advice from experienced ladies who have gone through this before.

My main questions are: how long does the swelling and bruising usually take to subside? Are there any daily care tips to help with recovery? For example, what should I pay attention to regarding cold compresses, diet, and sleep? I'm a little hesitant to go out right now, haha, and I don't know if this is a normal reaction.

If anyone has had a similar treatment, could you share your recovery experience, especially how you cared for your face in the first week or so? This is my first time having this done, and I'm a bit overwhelmed. Thank you all!
