Laser Thread Vein Removal (IPL)You don’t have to try to cover your thread veins anymore.A thread vein is a small blood vessel near the surface of the skin. The AW3 – Flash1 operator guides the visible light from the flash-lamp to the blood vessels needing treatment. The unique AW3 – Flash1 system carefully filters this light in two ways to ensure that only light with the correct characteristics (wavelengths) is allowed to reach your skin.Blood contains haemoglobin that absorbs the light and converts it into heat. This heat destroys the protein in the wall of the thread vein. As a result the veins will gradually, and safely, disappear after treatment.To ensure optimal light transmission to the blood vessel, a thin layer of gel (similar to that used in ultrasound examinations) is applied to your skin before treatment.
