How Broken Blood Vessels Cause Dark Circles under Eyes?
Actually what most people call broken blood vessels are not really broken blood vessels. What most people see are visible blood vessels on the skin in areas that they do not expect to see blood vessels. These small vessels are arterioles, venules, and capillaries. Arterioles carry fresh blood to the skin and venules take old blood away from the skin, back to the heart and lungs to be refreshed with oxygen. Capillaries connect the arterioles and venules. Normally blood vessels are deeper in the skin and not visible.
