Lasers are unique light emitting devices which give off a single very specific wavelength of light-targeted to eliminate one issue or problem. Certain vascular lasers have been designed to just remove blood vessels, spider veins, and red marks–causing no tissue effect or damage to any other elements of the surrounding skin. The laser beam targets the blood vessels, and seals them.
After the treatment, the skin is mildly red and swollen, and requires a few hours of icing to reduce the local inflammation. Some treated vessels look darker for a few days, then begin to fade and disappear. Generally, patients return to work that day or the next day. The spider veins slowly resolve over 4 weeks. One to three sessions, spaced fours weeks apart, give best results.
