Provided is a method for evaluating skin health, which method comprises: preparing a lipid sample from collected stratum corneum of skin of a subject； determining the quantities of a ceramide component A and a ceramide component B contained in the prepared lipid sample of the subject, the ceramide component A being selected from the group consisting of a non-hydroxyacyl-phytosphingosine ceramide component, a non-hydroxyacyl-6-hydroxysphingosine ceramide component, an ester-[omega]-hydroxyacyl-6-hydroxysphingosine ceramide component, and an ester-[omega]-hydroxyacyl-phytosphingosine ceramide component, and the ceramide component B being selected from the group consisting of a non-hydroxyacyl-sphingosine ceramide component and an [alpha]-hydroxyacyl-sphingosine ceramide component； calculating the ratio of the determined quantity of the ceramide component A to the determined quantity of the ceramide component B； and evaluating skin health of the subject from the calculated ratio.本發明係一種皮膚之健康之評價方法，其係由被試驗體之皮膚角質層之採取物製備脂質試樣， 分別對所製備之被試驗體之脂質試樣所包含的選自由非羥基醯基-4-羥基雙氫神經鞘胺醇・腦醯胺成分、非羥基醯基-6-羥基神經鞘胺醇・腦醯胺成分、酯-ω-羥基醯基-6-羥基神經鞘胺醇・腦醯胺成分、及酯-ω-羥基醯基-4-羥基雙氫神經鞘胺醇・腦醯胺成分所組成之群中之1種腦醯胺成分A、與選自由非羥基醯基-神經鞘胺醇・腦醯胺成分及α-羥基醯基-神經鞘胺醇・腦醯胺成分所組成之群中之1種腦醯胺成分B進行定量， 算出定量所得之腦醯胺成分A之成分量相對於腦醯胺成分B之成分量之比， 根據所算出之比而對被試驗體之皮膚之健康進行評價。
