Laser treatment of spider veins on legs using the GentleYag:

During laser treatment, a laser is applied to the skin over your spider veins. Laser energy causes your spider veins to coagulate and shrink. Laser therapy is most effective for small and medium size veins. You are likely to experience mild discomfort similar to having a small rubber band snapping against your skin. Treatments usually do not require sedatives, pain medications or injections of local anesthetic.

Immediately following treatment, spider veins will be darker and more visible. Over two to six weeks, your spider veins usually fade. After each treatment, you will see a 30 to 40 percent improvement. An average of three treatments will be required for desired results.

Laser treatment of spider veins on face:

Laser therapy is effective on facial spider veins. Laser treatments may cause minor bruising that usually improves within a week, but often, recovery is immediate. Two or four treatments may be required to achieve your desired results. After each treatment you will see a 70 to 80 percent improvement of the appearance of spider veins on you face. Immediately following treatment, you can apply makeup to give your face a more presentable appearance.
