here are a number of different laser treatment devices that are designed specifically for the removal of spider and reticular veins. These devices utilize light energy that’s finely tuned such that it is selectively absorbed by oxyhemoglobin in the blood and converted into thermal energy. When applied to the the skin, this intense heat causes rapid coagulation of the blood, injury to the vein, and thrombosis (clotting) of the target vessel. Procedure is up to 30 minutes, free followup six weeks post procedure.
