The purple color of the blood vessels in the legs is due to the dilated and tortuous capillaries in the legs, which can appear as spider-like dilated capillaries in the legs, which are at the very end of the body. This condition is a type of varicose vein and can be treated with local injection of sclerosing agents, which is not ideal for conservative treatment because it is not a coarse vasodilation. In addition to the vascular factor, it is also related to the body’s hormone, such as the increase of estrogen, so that the capillaries on the legs are dilated.
