One of the most common skin injuries that lead to skin discoloration is called bruise. This is when the blood from damaged blood cells deep beneath our skin collects close to the skin surface which can cause a bluish to black colored mark.
The typical cause is when our body parts bump into something of the other way around.
People who tend to vigorously exercise also have the likelihood to experience this like weight lifters and athletes. This is due to microscopic tears of blood vessels beneath their skin.
There are also unexplained bruises that are likely to happen without a clear reason. This can be related to a bleeding disorder specifically if the mark is associated with bleeding gums or nose.
