Abstract
A laser treatment method is provided which removes pigmentations, lesions, and abnormalities from the skin of a living human. The methodology comprises a carefully controlled irradiation of the chosen treatment site on the skin of a living human; avoids the creation of cosmetically disfiguring scars; and eliminates the typical hypopigmentation as well as the pitting and other changes in skin texture normally accompanying conventionally known laser treatment techniques.
Claims8
A laser treatment method for removing a tattoo from the skin of a living human, said method comprising the steps of:
- irradiating on a first occasion a chosen treatment site on the skin of a living human of about 1-100 millimeters in diameter with a beam of pulsed light from a laser delivery system, said pulsed light having a wavelength from about 600-1,100 nanometers, fluences of about 1-20 Joules per square centimeter, and a pulse duration of about 10-300 nanoseconds;
- maintaining said irradiation to disrupt the tattoo on the chosen treatment site on the skin of the living human until a color change endpoint on the skin surface is achieved by said laser light treatment while largely avoiding the destruction of normal skin structures and cells;
- allowing the skin at said irradiated treatment site to heal for a time period not less than about 7 days and not more than about 70 days;
- and then
- irradiating on at least one subsequent occasion the chosen treatment site on the skin of the living human with another pulsed beam of laser light having a wavelength from about 600 to 1,100 nanometers, fluences of about 1-20 Joules per square centimeter, and a pulse duration of about 10-300 nanoseconds, said subsequent irradiation occasion being repeated as necessary to achieve substantial clearance of the chosen treatment site on the skin.
