Many short dresses have been ruined by these thread-like clusters. Caused by injury, genetics, pregnancy, or simply aging, what we call spider veins are actually broken blood vessels. Injections (sclerotherapy) can help reduce there appearance, but if you’re needle-shy, consider laser treatment. One laser in particular (a V-beam) sends a strong burst of light through the skin, breaking up spider veins nonsurgically. They are then reabsorbed, and the treated cluster is gone for good.
