A contusion, or bruise, is a reddish-purple discoloration of the skin that doesn’t blanch, or turn white or pale, when pressed upon.
Bruises typically form when a localized injury, such a blow or impact, causes capillaries to break open and leak red blood cells under the skin.
A person may start to bruise more easily than before for a number of different reasons, though bruising doesn’t necessarily indicate a serious health issue.
