Abstract:
A laser depilation apparatus for performing depilation on a skin by irradiating the skin with a laser beam, the apparatus comprising:first irradiation means including a laser source for emitting a laser beam for depilation and a light delivery optical system for delivering the depilation laser beam emitted from the laser source into a first predetermined range to irradiate the range; detection means, including a CCD camera for forming an image of a surface of the skin within at least a first range; an image processor for processing the image and detecting thickness of a hair follicle based on an amount of melanin existing along the hair follicle; irradiation condition setting means for variably setting at least one of irradiation time of the depilation laser beam and irradiation power based on the detected hair follicle thickness; and control means for controlling the first irradiation means based on a setting set by the irradiation condition setting means.
