Spider veins are small purple, red and blue vessels that are typically visible through the skin, and resemble a twist and turn appearance. They are most commonly found on the legs and face and can be caused by a number of factors, including genetics and hormonal changes.
The non-surgical treatment of spider veins, also known as Sclerotherapy, works by injecting a solution into the veins, causing them to fade and eventually disappear.
This medical procedure involves an injection of a sterile solution, generally a salt solution, directly into the vein itself. Irritating the lining of the blood vessel, the solution causes the vein to scar and collapse, rerouting the blood through another vein. Over time, the collapsed vein is reabsorbed into the skin, causing it to fade from view and disappear.
Once treated, spider veins typically fade within a few weeks, but can take up to a month for full results.
