The development of redness in any area of the body is usually caused by the blood flow traveling through a network of blood vessels within the skin. The greater the blood flow in a given area, the redder the skin will appear. Normal networks of blood vessels are set deep within the skin, thereby limiting the appearance of excessive redness, even in areas with higher blood flow. However, there are aberrant, localized, or broken small blood vessels that can sit at the skin’s surface. These are referred to as broken capillaries, spider veins, or angiomas. The reason these vessels develop is usually due to genetics or inherited causes.
