In many cases, spider veins are not a direct result of poor circulation. They are typically localized and superficial—meaning they affect veins close to the surface of the skin and do not always reflect how well blood is flowing deeper in the body. If you have noticed tiny, colorful, red veins on your legs, they are probably spider veins or telangiectasia. Minimally invasive procedures like sclerotherapy or laser therapy can eliminate spider veins with little to no downtime.
