Thread veins or spider red veins are small unsightly superficial red, purple or blue veins that occur around the nose and across the cheekbones and chin, on legs or in fact anywhere on the body. These broken veins appear when the vein dilates and become larger so they are visible through the transparency of the skin. Thread veins are extremely common and completely harmless, but sometimes can be embarrassing. The causes of thread veins are unknown although they may be caused by changes in temperature, damage from sun expose, smoking, hormonal changes, alcohol and prolonged standing as well as being a possible inherited condition. In just a few treatments using the gentle power of laser, you can greatly improve the appearance of skin which is disfigured by unwanted red veins.
