<p>PURPOSE: To detect the extent of residual cosmetic objectively. CONSTITUTION: A skin 2 15 irradiated with infrared light emitted from an infrared light source 1 and the reflected light is introduced through a bandpass filter 3 and a chopper 4 to a detector 5. Based on an output from the detector 5, absorbance is detected at an absorbance calculating section 6 for first and second lights and values, corresponding to the gradient of both absorbances, are calculated at a gradient calculating section 7 before being converted into an extent of residual cosmetic at a converting section 8.</p> |
