SOME INTERRELATIONS BETWEEN SEBUM, SWEAT AND THE SKIN SURFACE

[摘要] Sebaceous lipid does not disperse in water, but spreads over a restricted water surface as a lens- monolayer system. Considerable amounts of lipid may be redistributed by this mechanism. Sebum exists as a multi-molecular surface layer on dry skin, and does not penetrate cornified epithelium to any extent.
