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 consumer's skin condition. Therefore, it is common for a salesperson at a cosmetics store to measure the skin condition of a consumer using a measuring device and propose the most suitable cosmetics based on the measurement results.

2. Description of the Related Art Conventionally, as a technique for measuring skin condition, a technique for measuring skin condition using a sensor and a camera is known (see, for example, Patent Document 1).

JP 2003-329674 A

In practice, human skin is exposed to various physical stimuli. The skin shows a reaction (hereinafter referred to as “irritant reaction”) in response to physical stimulation. There are individual differences in stimulus responses. It is preferable to select skin care cosmetics in consideration of such irritation reactions. In other words, in order to provide optimal skin care cosmetics, it is necessary to know individual stimulus responses.

However, the measurement results obtained from the sensor and camera of Patent Document 1 have no correlation with the stimulus response. The measurement results of Patent Literature 1 are estimation results based on information acquired by the sensor and camera, and do not represent actual stimulus responses.

In other words, in Patent Document 1, individual stimulus responses to physical stimuli to which human skin is actually exposed cannot be measured.

It is an object of the present invention to measure individual stimulus responses to physical stimuli to which human skin is actually exposed.

One aspect of the present invention is
a stimulus applying unit that applies a physical stimulus to the subject's skin;
a measurement unit that measures the stimulus reaction of the subject to the physical stimulus;
A measuring device comprising:

According to the present invention, individual stimulus responses to physical stimuli to which human skin is actually exposed can be measured.
