Vascular lesions are the result of lots of vessels, or large vessels, that form directly underneath the skin. Because the vessels are visible through the skin, this results in a red appearance. Lesions can occur in many sizes, shapes and forms all over the body, and tend to be more noticeable in people with fair or thin skin.
Vascular lesions may be hereditary or caused from any constant exposure to excessive blood stimulation such as alcohol, caffeine, hot drinks, physical exertion, excessive spicy foods, high blood pressure, drugs or sun exposure. They can also be common in those whose skin gets red or flushed easily.
