Why does skin bruise? I mean, when you see a bruise, what exactly is it?

Answer:
it is blood vessels broken upon impact. if you hit your knee or shin or any part of your body and want to avoid a bruise, rub it right after it's hit and you will break up those blood vessels and won't bruise.

Bruises are where bleeding has occured under the skin - often from trauma such as bumping it on something. I occassionally get bruising under my chin if I eat certain foods - a chemical in the food (MSG) causes the blood vessels there to leak
