Zusammenfassung: | The stratum corneum is the superficial cornified layer of the skin that provides a barrier to water evaporation and, as such, is essential for terrestrial life. In addition to preventing water loss, the stratum corneum also reduces the permeation of undesirable molecules from the external environment. The stratum corneum consists of dead cells (corneocytes) embedded in a lipid-rich (fatty-acid, ceramide, cholesterol) matrix. Both the corneocytes and the intracelluar lipids are derived from epidermal keratinocytes. This structure of corneocytes embedded in lipids has given rise to a brick (corneocytes) and mortar (lipids) model of stratum corneum structure and function. It is thought that much of the barrier properties of the skin can be attributed to this structure. Substances deposited on the skin must traverse this structure through a tortuous path to gain access the underlying viable layers of the skin. Substances that are irritating to the skin often initiate an elaborate cascade of immunological events once they contact viable skin cells. These events ultimately lead to skin inflammation.
Facial tissue is provided comprising a tissue substrate, a hydrophilic nasal secretion skin irritant sequestering agent and a hydrophobic nasal secretion skin irritant sequestering agent. In one embodiment the sequestering agents are comprised of modified and non-modified clays. In one embodiment the skin irritants are bound to sequestering agents present on a substrate. In another embodiment the skin irritants are bound to sequestering agents present on the skin. |
