본 발명의 과제는, 각질층 상태를 보다 간편하게 평가하는 방법을 제공하는 것에 관한 것이다. 각질층 시트에 대하여 수용성 염료의 용액을 접촉시켜, 염색 강도 또는 형광 강도를 계측함으로써, 각질층 상태의 평가를 간편하게 행할 수 있게 된다. 본 발명의 수용성 염료를 이용한 각질층 상태의 평가 방법을 응용함으로써, 화장료 또는 미용 처치의 각질층 개선 효과에 관해 평가하는 방법을 추가로 제공한다. The invention relates to providing a method for more conveniently evaluating stratum corneum condition. A stratum corneum sheet is contacted with a solution of a water-soluble dye, and the staining intensity or fluorescence intensity is measured to allow convenient evaluation of the stratum corneum condition. There is further provided a method for evaluating the ameliorating effect of a cosmetic or cosmetic treatment on the stratum corneum, by implementing the method for evaluating stratum corneum condition using a water-soluble dye according to the invention.
