How does laser light removal of unwanted blood vessels work?
Lasers are non-invasive light therapy devices. The laser generates a pulse of intense, concentrated light, which is directed through a hand piece gently aimed at the treatment site. The laser energy passes through the skin to the blood vessels you wish to have eliminated, and the energy is absorbed by the pigment in the blood, causing damage to the lining of the target blood vessel without damaging the surrounding tissues or the skin. The laser is pulsed, or turned on, for only a fraction of a second. The blood vessels, which have been destroyed, are reabsorbed by the body, and the flow of blood is directed back down to the deeper vessels where it belongs. The surface of the skin is protected by an air-cooling device that blows on the skin before, during, and after the treatment. The laser can be used just about everywhere on the body, and usually requires no anesthesia or other treatment. Even sensitive areas such as the nose and cheeks can be treated easily with little discomfort. In
