Treat broken blood vessels, spider veins, & skin imperfections. The Diolite® Iridex Laser generates an intense beam of light to deliver energy to a specific site, through a small hand piece connected to the laser. The laser light is absorbed by blood vessels and melanin/pigment (black or brown discoloration found in the skin) causing destruction of facial veins and sun spots by heating unwanted cells while leaving the healthy cells intact. The Diolite® Laser is best used on vascular lesions, such as Telangectasias or tiny red blood vessels, and Cherry or Spider angiomas, which are usually little red spots or web like blood vessels. After your treatment, avoid hot baths, saunas, alcohol, spicy foods, humidity, and sun exposure (can cause scarring). Do not exercise the night of the treatment.
