Side Effects of Laser Spider Vein Treatment?

Hi AAmom.  It's likely that the facility considering this procedure for you is asking about your skin type and tanning habits because they are not using the correct technology.  In the legs, the best laser for small spider veins (less than 1mm) is the long pulsed Nd:Yg laser (1064).  

Using this laser, even if you are olive skin toned, is not a problem.  We use it for African Americans with spider veins and it is perfectly safe.  It is likely this facility is trying to use an IPL or pulsed dye laser, which is an inferior technology for the legs.  We would recommend finding a facility that uses the proper laser technology or as others have suggested consider sclerotherapy.  Good luck.

Although topical lasers can be used for leg spider veins, the gold standard for leg spider vein therapy is sclerotherapy.  I would recommend that you see a vein specialist for an evaluation before commencing spider vein treatment in a spa setting.
