I got hit in the face and i dont want to get a blackeye, what could i do to make it better and what things should i avoid.

Duck next time.: Applying ice or a bag of frozen peas to the area as soon as possible will reduce the amount of bleeding from damaged vessels. This , however, will not remove the blood that has already been leaked into the skin. Heat can be applied after a couple of days to speed the bruise resolution. Anecdotally, some people believe that rubbing pineapple on the area will speed things up. Go figure.
