Many lasers are used in the treatment of spider veins. Lasers vary in wavelength and ability to effect damage. The most often used wavelengths are the 940 nm and the 1064 nm. Lasers speed up the treatment of spider veins by causing heat damage to the veins. The heat damages the vessel lining causing the veins to become smaller. In most cases, sclerotherapy is also used. The combination of heat and sclerotherapy gives a quicker resolution for a superior cosmetic result.
