I've heard that Arnica and witch hazel are good for healing/preventing bruises. Most importantly, keep any wounds you have clean. Use antiseptic wipes as soon as it happens, and if you have bandages, replace them often. Once the wound is starting to heal, give it some time to breath.
There are some treatments to help prevent scarring, one in the US is called Neosporin, but I know i've seen some available in the UK - Boots would be your best bet.
Hope this helps! Take care
