Molecular modeling has been used in the pharmaceutical industry for years to predict how a new molecule may work based on research conducted with molecules of a similar structure. The cosmetics industry has also begun to use this technology to predict the behavior of new molecules on skin and in skin care applications.

Welcome back to a continuing discussion regarding the new Registration, Evaluation and Authorization of Chemicals (REACH) regulation and its impact on chemical testing. It is the purpose of this series of articles to provide an overview of these existing validated in vitro methods, as well as new methods that are being considered for validation.

Using a texture analyzer to measure the tightness of the skin before and after the application of selected treatments, the authors demonstrate the potential of texture analysis instrumentation in testing the efficacy of skin care products and substantiating skin tightening claims.

Personal care efficacy tests are known to test the physical effects or toxicity of products, often omitting more abstract and possibly equally as important factors such as well-being.

In this article the results of six published tandem irritation studies are evaluated; possible mechanisms and clinical ramifications, albeit complex, are discussed. The clinical relevance of tandem irritation among cosmetics users and in many occupational settings appears obvious and suggests the need for further studies clarifying its principles and mechanisms.
