Abstract
A laser depilator comprising a unit for removing hairs from the skin, a light source for irradiating laser light, and a lens for irradiating the skin with the laser light irradiated from the light source while deforming the beam shape so as to conform to the shape of a region of the skin from which hairs are removed by the hair removing unit. Since removal of hairs shielding the laser light and irradiation of laser light for damaging hair roots can be carried out continuously, efficiency of depilation treatment can be enhanced. Furthermore, depilation can be carried out effectively through a simple arrangement because a shaved skin surface can be irradiated with laser light over a relatively wide range using a lens.
