The purpose of this study is to understand the changes in skin microflora, skin barrier function, and skin biochemical constituents in response to direct contact with model surfactants used in personal care articles. The results from this study will provide insights into the complex interaction between the skin microbiome and the epidermis after exposure to surfactants.
