Sclerotherapyis a minimally-invasive procedure for the treatment of spider veins. In some instances, it can also be used for the treatment of varicose veins.
During sclerotherapy, your vein doctor will use a very fine needle to inject either polidocanol or STS into your damaged veins. Hypertonic saline is not used at the Vein Wellness Clinics due to the increased risks of hyperpigmentation and skin damage. With the injections, the treated veins will be disrupted and collapse.
It’s normal to have some inflammation In the first 2 weeks that will resolve on its own. Gradually, the spider veins will begin to fade over the course of 4-6 weeks. The initial treatment is expected to improve the appearance by 50-70%. As a result, most patients will need second or even third sessions to have a complete response. This is true for both sclerotherapy and laser vein removal. We do not recommend any re-treatment before 6-8 weeks to allow sufficient time for the veins to fade.
