The Japanese toy giant BANDAI teamed up with cosmetics powerhouse FANCL to produce BIHADA KANTEI: a small digital skin condition checker that will be released on 30 november (suggested retail price 3.570 yen.).
The size of this gadget is limited (924 × 33 × 23mm), it looks like an USB memorystick, and doesn't take too much space in women's bags.  Skin condition is displayed in the range from 1,000 to 10,000,000 and up to 90 days of data can be stored, analyzed and visualized as graphs.  The "Skin Expert" is powered by 2 CR2023 batteries.
