As mentioned before, doctors have yet to find the cause of spider veins. If you have spider veins, you probably could care less about what causes them, and care only about getting rid of them.
Unlike varicose veins, where procedures like RF and Venaseal have become the go-to treatment, the best solution for the vast majority of spider veins is still injections. These are injections known as “surface sclerotherapy.” In this case, phlebologists choose from a variety of effective injectable agents (“sclerosants”) to treat spider veins. Every patient varies in the success of a sclerotherapy session, but results are typically commensurate with your phlebologist’s experience, and his/her ability to choose the best treatment protocol based on your skin type, and the size and location of your spider veins.
