How to care for swelling and bruising after a short treatment?

Hi everyone! I'm Yating. I recently had a short procedure in Seoul, and my face is a bit swollen and bruised afterward. I was wondering if anyone has any tips for home care?

The medical staff gave me basic instructions, but I'd like to hear from others who have had similar procedures in Korea about how they handled it. Like, how long to apply ice, what to eat, or any habits to avoid? I heard to avoid heavy makeup and strenuous exercise for the first few days, but I'm not sure if there are any other things I should be careful about.

If anyone has gone through a similar recovery process, I'd love to hear your experiences and advice! Also, please share what methods were most helpful to you. Thanks!
