Sclerotherapy treatments depend on a few things such as the area of the country you live in and the number of spider veins to be treated. In bigger cities such as LA or NY the treatments can be pricey. I would say the national average cost is $250 to $500 per half hour session. If the veins are confined to a few areas both legs could be treated in a half hour. Remember that it takes on average 2 to 4  half hour sessions to adequately treat the vessels. So you are looking at a range of $500-$2000. As with any dermatologic condition or cosmetic procedure it is always advised to consult a dermatologist to examine the veins and discuss any risks or costs.
