Spider veins are small, dilated capillaries that appear below the skin. They can appear red, blue, purple, and are usually thin and twisted to resemble the appearance of spider legs.
Varicose veins are large, raised, and swollen vessels that twist and turn. Spider veins and varicose veins are common on the lower extremities and can occur due to genetics, standing for long periods of time, obesity, and hormonal influences (pregnancy). These types of veins are more common in women than men.
With age, genetics, pregnancy, and lifestyle, the appearance of veins can become more prominent especially on the lower legs.
Sclerotherapy, or the injection of a saline solution, can be performed as a cosmetic treatment for spider veins and some varicose veins. It involves injecting each tiny venuole or varicose vein with hypertonic saline. To effectively remove all veins in an area, multiple treatments are frequently needed.
