Laser effects on the skin. Thermal (burn) injury is the most common cause of laser induced skin damage. Thermal damage is generally associated with lasers operating at exposure times greater than 10 microseconds and in the wavelength region from the near ultraviolet to the far infrared.
How do V-beam laser treatments work? During a V-beam laser treatment, an intense pulse of light will be sent into the skin. The blood vessels below the skin will absorb the light, thus destroying the blood vessels and allowing them to be reabsorbed into the body.
