Laser treatment is an appealing option to combat spider veins. You can expect to see improvement in the appearance of your leg veins immediately following the first treatment. The heat sensation from the laser’s wavelengths may be painful for patients. During the treatment, cooling system is provided to help reduce the pain from this heat sensation. Depending on the severity of the veins, two to five treatments May be needed for sufficient outcomes. Patients may return to normal activity immediately post-treatment. For large spider veins (larger than 3 mm), laser therapy may not be a practical option.
