  • System for treatment of acne skin condition using a narrow band light source
    Patent number: 7267673
    Abstract: The acne treatment devices use an array of LEDs, which emit monochromatic light substantially at a wavelength of 405 nanometers, which is coincident with the peak absorbance of light by acne porphyrins. The emitted light is directed from the light source to an acne area of the skin. The device can either be hand-held, with the LEDs mounted on a handle portion, or an LED can be mounted on a patch-like mounting element, which is adapted to be secured to the skin for longer exposure at less intensity.
    Type: Grant

    Date of Patent: September 11, 2007
    Assignee: Pacific Biosciences Laboratories, Inc.
