Abstract
A laser treatment method for removing unwanted human hair includes irradiating a treatment site with post-coherent light of selected wavelength and peak power level and post duration, and repeating the post-coherent laser irradiation on one or more subsequent occasions with selected light parameters. A therapeutic treatment device has a laser and associated support elements and has a dermatology handpiece with a distance gage, a conduit for applying pressure and/or cooling to the treatment site and, optionally, cooling elements.
Claims6
A laser treatment method for the removal of unwanted hair from the skin of a human, said method comprising the steps of
- irradiating on a first occasion a chosen section of human skin containing at least one hair growing within a hair follicular structure with pulsed coherent light with wavelength in the range 650-1000 nm, said light having a peak power level in the range 1-500 Watts and a pulse duration of 1-99 milliseconds, and said diameter of treatment beam being in the, range 1-5 mm,
- allowing the skin to heal for a period of 1-3 months, and
- irradiating on each of a set of subsequent occasions with pulsed coherent light with a wavelength in the range 650-1000 nm, said light having a peak power level of 1-500 Watts and a pulse duration of 1-99 milliseconds, and said diameter of treatment beam being in the range 1-5 mm.
