From an insider’s view, safety testing is an assumed step in the development of any product on the market. This puts the pressure on analytical and quality control efforts behind the scenes to ensure that ingredients and products meet or exceed expectations. In doing so, theoretically, no one else has to give it a second thought. For those who must give it considerable thought, this edition features two articles on testing, among other topics.

Botanical ingredients are interesting for their unique and complementary chemical diversities yet they are criticized for these very traits, which make quality assurance, reproducibility and good phytochemical characterization—required for successful high throughput screening, difficult. This article discusses these challenges as well as the benefits of large-scale screenings of botanical extracts that are currently used or developed for cosmetic product development.

From Elastin to Elastic Fibers, Part I: The In vitro Effects of a Natural Dipeptide on the Biological Cascade
By: Philippe Mondon and Ada Andre - Sederma, Franc…
The peptide N-Acetyl-Tyr-Arg-Hexadecylester (NATAH) was found to stimulate the synthesis of tropoelastin in cultured human dermal fibroblasts as well as augment the activity of all important actors in the assembly of elastic fibers, including Fibrillin 1, Fibulin 5, Decorin, LOX and Transglutaminase, among others. This is shown here both in monolayer cell cultures and in a 3D skin model.
