This work studies the applicability of a 96-well-based skin-mimetic artificial membrane permeability model to differentiate between topical pharmaceutical and cosmetic formulations. Results are compared with data obtained from in vitro Franz cell permeability measurements and reveal the applicability of this method to assess cosmetic formulation permeation and speed the discovery process.

Current in vitro methods to assess photostability and antioxidant activity do not account for the diffuse reflectance of skin. Described here is an in vitro test that addresses this variable, mimics end-use product conditions and models photodamage processes. The approach is employed to determine the efficacy of an antioxidant from the Camellia sinensis (tea) plant.

RNA interference (RNAi) is a gene-silencing technique that inhibits gene expression by causing the intracellular degradation of mRNA molecules. Since first reported in 1998, RNAi has sparked a revolution in molecular biology and has been employed in a myriad of biological contexts for the systematic evaluation of gene function.
