light and laser therapy: Intense light and laser therapy uses multiple wavelengths of light to treat dilated blood vessels in the face. Since the laser uses light, rather than needles or incisions, the treatment feels like a pinch or a snap of an elastic band. Both treatments take 15-to-30 minutes and are performed at six-to-12 week intervals. Patients may require several treatments initially, and may return annually for treatment of new blood vessels.
