First developed in the 1920s, sclerotherapy has withstood the test of time and proven to be an effective treatment for various vein conditions such as spider veins. Sclerotherapy is the most popular form of spider form removal because of its ability to effectively remove spider veins over the course of multiple treatments. In certain cases, it can also be used in conjunction with other spider vein removal treatments, such as cutaneous laser treatment or Veinwave ™.

How Sclerotherapy Works

In this rather quick and simple procedure, a solution called sclerosant (specifically, FDA-approved Polidocanol) is directly injected into a vein with an ultra-fine needle. The sclerosant makes blood vessels shrink instantaneously and causes the spider veins to collapse. The blood flow is then absorbed by healthier blood vessels. Shortly thereafter, the vessel becomes scar tissue and fades away. There can be multiple veins that are treated depending on the size and location of the veins and takes only 15 to 30 minutes to complete.
