Facial telangiectasias (spider veins) have been attributed to a variety of etiologies—most commonly chronic UV exposure, hormone therapy or changes, drugs or alcohol, heredity, and as a secondary phenomenon to many diseases. Therapeutic modalities have included electrodesiccation, dermabrasion, argon laser, and, more recently, the flash lamp–pumped pulsed-dye lasers.1 Initially, it was thought that these instruments had no potential to cause scarring. However, as with any device that delivers photon energy to the skin, untoward consequences, such as textural change, increased or decreased pigmentation, persistent erythema, or various forms of scarring are certainly possible.
