As you may know, sclerotherapy is a medical procedure that is useful for eradicating spider veins. We perform it frequently here at Elect Dermatology. One of our patients came back yesterday and gave us permission to share her before and after photos. You can see that after one treatment there is an approximately 80-90% improvement in visibility of the veins. We just want to give you all an idea of what this looks like after a single treatment.
