Facial vessels and vascular birthmarks can effectively be treated with the Candela Dye, Versapulse Laser or Intense Pulsed Light (IPL). The lasers release a precise and narrow wavelength of light that is absorbed by the hemoglobin pigment in the red blood cells. Thermal energy is then created causing the blood vessels to shrink and seal off. In majority cases, removal is accomplished after one treatment and rarely more than one treatment may be required.
