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.

This work evaluates the impact of a plasma treatment on test substrates to modify their surface energy, to more closely correlate in vitro SPF measurements with in vivo measurements—without chemically altering the test products. The authors chose the level of plasma modification to use on a substrate based on in vivo values; they explain how to choose it regarding specific formulas in a further paper.

Skin expresses enzymes that can metabolize endogenous molecules but little is known regarding how they impact the delivery of xenobiotics. This review of recent works shows that skin metabolism alters the dermal absorption of lipophilic compounds, which opens new areas of investigation regarding the safety and efficacy of topically applied cosmetics.

There are varying definitions, associations and overall impressions of fine lines and wrinkles among different consumer segments. The findings of this study offer invaluable insight into consumers’ opinions, and by qualitative in-depth interviews, they provide a well-defined vernacular for aging descriptors. This language is critical for developmental research, consumer evaluation and marketing within the cosmetic industry.
