Why do you have blue circles underneath your eye even though you get enough sleep what could this mean?

Often, the tiny blood vessels just under the skin can rupture or have other issues. Then the blood can seep under the skin. That's how bruises are formed. Some people have a genetic predisposition for this, and others don't develop it even after missing a lot of sleep. In short, there may not be a repair for the discoloration. Makeup could cover it. It could also be a sign of another issue, so I do recommend seeing a doctor if it bothers you, or becomes painful.
