The VBeam is a pulsed dye laser, which means that the laser energy is delivered in pulses and a dye is used to generate laser beams of different colors. Since the VBeam is used to treat dilated blood vessels, as in rosacea, it is often called a vascular laser. The target of the vascular laser is hemoglobin, the red protein in blood cells in the blood vessels. Skin cells that surround the dilated blood vessels are not damaged.
