Abstract: Provided is a method for detecting childhood atopic dermatitis using skin surface lipids. The method for detecting childhood atopic dermatitis in a test subject comprises a step of measuring an expression level of TARC gene or an expression product thereof in skin surface lipids collected from the test subject.

Abstract: Provided are a marker for detecting atopic dermatitis, and a method for detecting atopic dermatitis using the marker. The method for detecting atopic dermatitis in a test subject comprises a step of measuring an expression level of a gene or an expression product thereof contained in a biological sample collected from the test subject.

Abstract: A method of evaluating the health of skin, containing the steps of: preparing a lipid sample from a collected sample of a stratum corneum of a test subject; quantitatively determining respective contents of one kind of ceramide component A and one kind of ceramide component B included in the prepared lipid sample prepared from a collected sample of a stratum corneum of the test subject; calculating the content ratio of the quantitatively determined content of the ceramide component A to the quantitatively determined content of the ceramide component B; and evaluating the health of the skin of the test subject from the calculated content ratio; wherein the ceramide component A is selected from the group consisting of a non-hydroxyacyl-phytosphingosine ceramide, a non-hydroxyacyl-6-hydroxysphingosine ceramide component, an esterified ?-hydroxyacyl-6-hydroxysphingosine ceramide component and an esterified ?-hydroxyacyl-phytosphingosine ceramide component; and the ceramide component B is selected from the gro
