Patent ID: 7214222

Claim:
A laser depilating apparatus, for retarding a regrowth of hair comprising: a semiconductor laser for emitting a laser beam having a wavelength in a range of 750 to 900 nm and a power density in a range of 0.01 to 5 W/mm 2 ; a radiating head having a light path for guiding the laser beam and a laser irradiation surface so as to irradiate a skin surface subject to depilating treatment with the laser beam emitted from the semiconductor laser; and an irradiation condition control section for controlling an irradiation time of the laser beam to 100 msec or more per irradiation and an energy density to a range of 0.01 to 1 J/mm 2 , and configured such that an entire hair follicle tissue of the skin surface is heated to a temperature greater than 60° C. and less than 100° C. so that the regrowth of hair can be retarded through thermal damage to the entire hair follicle tissue when the skin surface is irradiated with the laser beam.
