Can writing on your skin cause blood poisoning?

Writing on your skin will not cause blood poisoning. Blood poisoning, also known as sepsis, is a serious medical condition in which the blood is infected with bacteria or other microorganisms. It is usually caused by bacteria entering the bloodstream through a cut, burn, or other wound. Writing on your skin with a pen or pencil does not break the skin or introduce bacteria into the body, so it cannot cause blood poisoning.
