PROBLEM TO BE SOLVED: To quantitatively estimate efficacy given to the skin by the external preparation as a temperature change amount of the skin regardless of whether or not the external preparation which is an estimation object actually changes the skin temperature in the estimation method for cold feeling given to the skin of the subject by the external preparation.SOLUTION: An actual change amount (T1-T0) of the skin temperature of the second region 1B is calculated by a temperature detection part 33 when the subject determines that the cold feeling at the two places given by an external preparation is the same by causing the subject to feel the temperature cold feeling given to the two different places (the first region 1A, the second region 1B) of the body of the subject and the temperature cold feeling given by a temperature adjustment part 32 at the same time, and based on this calculation result, the external preparation is estimated.SELECTED DRAWING: Figure 1 |
