This laser targets capillaries and red spots. Many people develop red spots on their skin as they age (capillary hemangioma). This laser effectively treats the capillaries in the skin to make the red spot go away. The laser wavelength is most highly absorbed by red pigments, so the blood in the capillary increases in temperature and strips off the non-stick coating inside the capillary itself. This lets the vessel close off. Many people also look for treatment of spider veins on the legs. This laser is also effective in reducing spider veins. Spider vein treatments do require several sessions.
