The laser uses a focused beam of light. In the treatment of veins, the wavelength of light is targeted to the pigment in the blood. The laser heats up the small vein and destroys it. The laser beam is focused and does not damage the nearby skin tissue. Over a period of four to six weeks, the vein is reabsorbed by the body and disappears.

It is generally recommended that the treatments be spaced four to six weeks apart. If new veins appear, additional treatments are required for optimum results. The results of laser treatment for spider veins are not immediate. After the laser therapy, the vessels underneath the skin will gradually change from a dark blue to light red color, then eventually disappearing in two to six weeks. Depending on the size and number of veins, two to six treatments will be needed. The treatments are usually done 4-6 weeks apart. Those with a tendency towards vascular problems will most likely require additional treatments. You should avoid sun exposure in the treatment area for two weeks following the procedure.
