Lumenis Lightsheer ET 400 MS Leg Veins – Approximately 50% to 60% of men and women have unsightly leg veins. While sclerotherapy is still considered the treatment of choice for the removal of superficial leg veins, many vessels may be too small to inject or patients may have an aversion to this invasive procedure. The LightSheer diode laser system can provide an alternative method of treatment that requires no painful injections.
