Laser therapy is most effective for small and medium size spider veins. During a laser treatment, the laser is applied on the spider vein. Laser energy causes your spider veins to coagulate and shrink. At first, the spider vein will become darker and more visible. However, within 2-6 weeks the spider vein will fade significantly. After each treatment, you will see a 70% to 80% improvement in the appearance of facial spider veins and 30-40% improvement of leg spider veins.
An average of two-three treatments will be required at 2-3 month intervals to produce desired results.
