I assume you are talking about sclerotherapy injections for spider veins. I make it very clear, verbally and in writing, that an area of veins could take 3-5 treatments. However, you should also be evaluated for feeder "reticular" veins below the surface, which also need to be addressed. Normally, a special light called transillumination is used to see below the surface.

Because it takes several treatments to see the results you desire.

The smaller the vein, the harder it is to treat. Sclerotherapy or topical laser for very small veins usually takes several treatments. I tell my patients that sclerotherapy is a process and may take 3 to 5 treatments, each spaced 6 weeks apart to achieve results. You should also note that this treatment is not permanent and that some veins will always recur and some new ones will grow over time.
