Lasers send wavelengths of light directly into the vein. This causes the vein to heat up internally and turn into scar tissue which will gradually fade or disappear. Technological advances in the recent years have helped to make the laser treatments safer and more effective than ever. Like sclerotherapy, such treatment can be performed in a dermatologist’s office and does not require anesthesia.
Many types of lasers are used to treat veins for different skin types. Your dermatologist will recommend the best type of treatment, based on the size and location of the veins to be treated. For best results, laser therapy may be combined with sclerotherapy. To prevent permanent skin discoloration, people of color may require treatment that emit specific wavelengths of light.
While generally spider veins completely disappear, new spider veins may re-appear in the same general area and it is also possible for large veins to re-occur.
