Description

The present invention relates to a measuring device and a server.

In general, skin care cosmetics used on the skin are preferably selected in consideration of the condition of the consumer's skin. Therefore, in cosmetics stores, it is common for sales staff to measure the condition of the consumer's skin using a measuring device and propose the optimum cosmetics based on the measurement results.

Conventionally, as a technique for measuring a skin condition, a technique for measuring a skin condition using a sensor and a camera is known (see, for example, Patent Document 1).

In reality, human skin is exposed to various physical stimuli. The skin exhibits a response in response to a physical stimulus (hereinafter referred to as "stimulus response"). There are individual differences in the stimulus response. It is preferable to select skin care cosmetics in consideration of such a stimulating reaction. In other words, in order to provide optimal skin care cosmetics, it is necessary to know the individual stimulus response.

However, the measurement results obtained from the sensor and camera of Patent Document 1 have no correlation with the stimulus response. The measurement result of Patent Document 1 is an estimation result based on the information acquired by the sensor and the camera, and does not show an actual stimulus response.

That is, in Patent Document 1, it is not possible to measure individual stimulus responses to physical stimuli to which human skin is actually exposed.
