Spider veins, or telangiectasias, are those small red, blue and purple blood vessels that appear most frequently on the face and thighs. Laser Vein Removal is a non-invasive procedure known as VascuLight LaserTreatment. Lasers deliver concentrated light in a specific wavelength of the spectrum. Each wavelength is absorbed by a different target or chromophore, such as pigment, blood, or water. The light pulses heat the blood within the leg vein. The heat of the blood affects the vessel lining, which causes the vessel to constrict and eventually fade from view. This same technology can also be used to remove or reduce unwanted facial veins.
