This simple, time-proven treatment removes unsightly spider veins of the legs. A very fine needle is used to inject a safe, salt water solution into the veins. One may experience a momentary burning, followed by a minute or two of cramping. Patients are advised to wear leggings or support hose for a week following the procedure, so fall and winter are the best times to receive treatment. The veins lighten gradually over a 3 to 4 week period. Generally 3 to 5 treatments are required to achieve complete clearing.
