Bruises redux: If you have no medical cause or reason for bruising, realize that these types of bruises we usually see you around the dorsal arms, and are due to aging. Sometimes sunlight exposure will cause a thing of the skin on the arms and i breakage of the small supportive collagen bundles which act like railroad ties and which holds the blood vessels intact. If you are aging and have a bruise and know that.
