In addition, as an effect of changing the skin color within a range that does not give a sense of incongruity, palatability is high in an appropriate color change, and the average value of ΔE is preferably 1.5 or more and less than 9.0, and preferably 3.0 or more and 6. Less than 0 is more preferable. If the average value of ΔE is less than 1.5, the change in color may not be known, and if it is 9.0 or more, the color may change too much and feel uncomfortable.
From the obtained average value of ΔE, the following evaluation criteria were used to evaluate the effect of changing the skin color immediately after application within a range where there is no sense of incongruity (skin color change).
〔Evaluation criteria〕
Δ: Average value of ΔE is 0.0 or more and less than 1.5 ○: Average value of ΔE is 1.5 or more and less than 3.0 ◎: Average value of ΔE is 3.0 or more and less than 6.0 ○: Average of ΔE The value is 6.0 or more and less than 9.0 Δ: The average value of ΔE is 9.0 or more and less than 12.0 ×: The average value of ΔE is 12.0 or more

<Sustainability of the effect of changing the skin color within a range that does not feel strange (skin color change)>
About the sustainability of the effect which changes skin color within the range which does not feel strange, the Lab value was measured with the simple spectral color difference meter (NF333, Nippon Denshoku Industries Co., Ltd.).
For 20 male and female panelists (10 males, 10 females, 20 to 40 years old) with Lab values (L value 56 to 60, a value 8 to 10, b value 20 to 22) The face was washed with 1 g of a face washing form “Plant Monogatari” (manufactured by Lion Corporation) and towel-dried, and then 0.5 mL of each skin cosmetic was taken on the palm and spread on the face. After application, 5 minutes later, the Lab value was measured and the normal life was spent for 4 hours. Thereafter, the Lab value was measured again, ΔE ′ was calculated based on the following formula, and the average value of ΔE ′ of 20 professional panelists was obtained.
ΔE ′ = [{(L value after 5 minutes after application) − (L value after application and normal life for 4 hours)} ² + {(a value after 5 minutes after application) -(A value after applying and living a normal life for 4 hours)} ² + {(b value after applying and 5 minutes after application)-(after applying and living a normal life for 4 hours) b value)} ² ] ^1/2
In addition, regarding the persistence of the effect of changing the skin color within a range in which the skin color does not feel uncomfortable, the smaller the change in color, the higher the preference, and the average value of ΔE ′ is preferably 0.0 or more and less than 2.0. 0.0 or more and less than 1.0 is more preferable. If the average value of ΔE ′ is 2.0 or more, the color may change too much and the sustaining effect of the skin color change may not be sufficient.
From the obtained average value of ΔE ′, the following evaluation criteria were used to evaluate the sustainability of the effect of changing the skin color within a range in which the skin color does not feel uncomfortable (skin color change).
