The stratum corneum (SC) represents the outermost layer of the mammalian skin, exhibits the main skin barrier and plays an important role in the water penetration pathway through the SC. Knowing the structure and properties of the SC at the molecular

The lipid matrix of the stratum corneum (SC) is the major diffusion-rate-limiting pathway by which most drugs intracellularly pass the SC. The major lipid classes extracted from the SC are ceramides, cholesterol and free fatty acids. Ceramides that c

We report the potential use of a noninvasive method of photothermal beam deflection (PBD) in pharmaceutical research exemplifying the determination of drug content in semisolid formulations and mapping the lateral drug diffusion into an artificial me
