A body hair luminescence aesthetic device comprises optical assemblies which project body hair aesthetic luminescence. The integral value of the intensity of body hair aesthetic luminescence in the 400-700 nm wavelength range is greater than that in the 700-1200 nm wavelength range, and the integral value of the intensity of body hair aesthetic luminescence in the 400-500 nm wavelength range is smaller than that in the 500-600 nm wavelength range.
