Injection sclerotherapy is the gold standard for treatment of spider veins. Using a special light, the vein is isolated, and a small amount of medication (sclerosant) is injected inside the vein. The medication "closes" the vein and stops the flow of blood.
Although the appearance of treated veins improves (diminishes) immediately, the veins are slowly absorbed by the body over the course of several weeks or months. Typically, several veins can be treated in one session, and more than one session may be required depending on the extent of spider veins. It is also possible that repeat injections may be necessary since some veins are more "stubborn" than others.
It is important when scheduling your spider vein treatment to consider the timing in which treatments are preformed in relation to sun exposure.
We recommend avoiding sun exposure (including tanning beds, etc.) 1-2 weeks after a treatment is performed. In addition, we recommend using a sunscreen with an SPF of 30 or greater for 3 months post treatment.
