Composition comprising a human culture derived in vitro from keratinocytes that has been stratified in squamous epithelium (skin equivalent), said skin equivalent having a surface electrical capacitance of 40 to 240 pF, measured as the difference in reading over an interval 10 seconds, and in which the combined content of ceramides 5, 6, and 7 in said skin equivalent is 20 to 50% of the total ceramide content, in which said keratinocytes are almost diploid immortalized keratinocyte cells. |
