At Allyn Aesthetics we use a long-pulsed yag laser, one of the many wavelengths available on our Rohrer Spectrum device. The laser seeks out the pigment in the blood cells within the vein and denatures them, causing them to become sticky, thereby sealing the valls of the vessel together. Some tiny veins are obliterated right away while other, larger vessels may require several treatments for eradication. We do not treat large, bulging, or obviously sclerosed (corded) veins.
