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 spider veins. You are likely to experience mild discomfort similar to having a small rubber band snapping against 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 70% to 80% improvement in the appearance of face spider veins and 30-40% improvement in leg spider veins.

An average of three treatments will be required at three-month intervals to produce desired results. Combination therapy can be considered and beneficial if you have small, medium and large spider veins.
Laser treatment spider veins in the face may cause minor bruising that usually improves within a week, but often, recovery is immediate. Two to four treatments may be required to achieve your desired result. Immediately following treatment, you may apply makeup for a presentable appearance.

Expected Duration of Results. Regardless of treatment, you should anticipate the development of new spider veins over time, just as you would if your spider veins had not been treated. Spider vein therapy treats current spider veins but does not prevent new ones.
