The sclerotherapy is a common used not surgical but cosmetic procedure. The very small capillaries, which are normally superficially in the skin, become dilated and noticeable. In these cases spider veins, teleangiectasias, little red spots and simple or smaller-bigger complex formations of dilated veins will appear. With aging the veins, which already exist, will strech, more and more dilated veins will develop. With the increasing number of dilated veins, they will fuse and slowly bulk from the skin around.
