Abstract
A photometric skin condition analyzer is provided which exploits the light refraction and Rayleigh scattering from small particles, such as droplets of oil, deposited on optically smooth sampling surfaces of a sampling pellet. Light emitted from an optical source is passed through the sampling surface and focused onto an optical detector. The output signal of the detector is displayed to give an indication of the degree of oiliness of the skin.
