Because the laser energy is directed toward the vein, the surrounding tissue remains unharmed. Patients report that laser pulses deliver a sensation similar to the snapping of a rubber band against the skin. Discomfort is further minimized by GentleMax Pro’s patented DCD™ cooling device, which releases cooling bursts of cryogen with each laser pulse. You will need a series of treatment sessions to see results. Expect anywhere from two to four treatments spaced four to six weeks apart. Following your treatment regimen, the veins will either disappear or gradually change color from blue to light red, and they will eventually diminish over the course of several weeks after your last session.
