Spider veins are small dilated blood vessels that appear on the skin. They are caused by increase pressure in the veins. (They have an appearance of a spider web)
Spider veins are caused by structural abnormalities of the blood vessels, which causes blood flow back into the veins. The constant pooling increase the pressure and blood within the vein, thus weakening the vessel wall.
This process is used to eliminate Spider Veins. In order to achieve the desired result, a chemical agent is injected into the problematic veins to shrink them. Overall, in two to three days, symptoms begin to disappear and 70-80 percent of the unsightliness is gone. Treatments are done 6 weeks apart. The number of treatments required depends on the amount of veins being treated.
