Abstract
An optical cosmetic device for body hair includes an optical system that emits cosmetic light for body hair. The optical system includes a light source, a control unit that controls at least one of a voltage and a current supplied to the light source, and an optical filter that changes a spectrum of light emitted from the light source. An intensity integral of the cosmetic light for body hair in a wavelength range of 400 to 700 nm is larger than that in a wavelength range of 700 to 1200 nm. An intensity integral of the cosmetic light for body hair in a wavelength range of 400 to 500 nm is smaller than that in a wavelength range of 500 to 600 nm. The largest one of intensity peaks of the cosmetic light for body hair is in a wavelength range of 400 to 570 nm.
