The Cutera Excel V laser uses a wavelength of light that passes through the skin and is absorbed by the blood in the vein generating heat. The heat causes the vein to close and after healing the vein will no longer be present. This treatment is used for spider veins that are too small for needle access.
—— Sclerotherapy ——
Sclerotherapy uses a tiny needle to introduce an FDA approved medicine into the unwanted veins. This will cause the vein to close and eventually resolve.
