The "Hada Memori" (skin memory) programme allows women to keep tabs on their complexion and track changes over time by storing records in
the cloud.
Users can also share their data through social networking sites, said IT giant Fujitsu, which plans to use the information to target advertising of beauty products.
A spokeswoman said the skin system comes with a small card that has a 15 millimetre (0.6 inch) hole, which must be pressed to the cheek. The smartphone's camera then takes a picture of the skin and analyses the result.
The Hada Memori is the first of a series of devices that will measure users' stress levels, exercise habits and quality of sleep, helping the company gather a significant pool of health data which it can then sell on.
"We will be able to offer the data to service providers eventually," said Hayuru Ito, senior manager of Fujitsu's strategic planning division.
Fujitsu is aiming to have one million users of the system in the next two years.
