What is good for reducing swelling?

I couldn't set a surgery date because I was resting, but I can't wait until summer, so I set a date.
 It would be better to rest for 2 weeks, but I'm going to rest for a week and go to work with a plate on my face since I'm going to have the surgery anyway. ㅠ
 But what will help the most with reducing the swelling after surgery?
 I heard that walking is the best, but are there any good methods other than walking?
 I'm getting surgery at ㅇㅇㄱㄱ, and they say they do laser treatment for swelling after surgery, but I don't have time so I don't think I can go often.
 What else is good for reducing swelling other than walking? Those who've had surgery, please give me some tips.
 Swelling and such don't help, right......? ㅠㅠㅠ
