Thread veins (also known as spider veins, broken capillaries or telangiectasia) are visible blood
vessels often affecting the face and legs. Thread veins can safely be reduced using laser, in a
process called photothermolysis. We use Alma Harmony XL Dye VL for facial veins and an Nd:
YAG for larger leg veins. The veins are subjected to short pulses of visible light, which targets
the haemoglobin, heating just enough to damage and break down the vessel wall without
affecting the surrounding skin. Damaged blood vessels are reabsorbed by the body, making
them less visible or destroying them completely.
