Thread veins, also known as spider veins or venous flares, are the result of small vessels under the skin dilating. They typically appear in older people – as the skin starts to get thinner, veins are more easily seen. Thread veins can also occur during pregnancy and are more common in people who are overweight or smoked.
A common treatment for thread veins, Intense Pulsed Light (IPL) is a highly effective treatment. The treatment emits a bright, white light, which is absorbed into the vessels right under the skin. The heat generated by the white light forces the blood in vessels to coagulate and destroy the vessels, effectively removing them from the skin surface. The vessels are easily reabsorbed back into the skin.
The procedure is pain free, but the coagulated blood can cause some bruising for skin pigmentation. Both typically disappear in just a few days.
