  • Patent number: 4160271
    Abstract: A cosmetic analyzer unit has a color index section and a skin index section, with a digital numerical display for each section. Each section of the analyzer contains a plurality of keys by actuation of which an individual may answer multiple choice questions concerning her cosmetic determining characteristics. As the keys of each section are actuated, the corresponding index signal is numerically modified in accordance therewith, so that after all the multiple choice questions of a section have been answered, the corresponding color index or skin index signal is numerically displayed. A display unit is provided for displaying a number of skin color imparting cosmetics, and has keys corresponding to various color index ranges. When an individual presses the key corresponding to the range which includes her color index, skin color imparting cosmetics suitable for use by said individual are illuminated by the display.
