Skin Aging Characteristics of Russian Women

There appear to be no published studies on facial aging in Russian women, despite clear interest from the industry in this market. In order to formulate products, it is necessary to understand the end consumer. This article therefore explores a recent study of 203 Russian women and describes their aging specificities versus other, more studied Caucasian populations.

C&T Summit Explores Proteomics to Examine Hair Damage

Damage to the hair shaft can lead to the breakdown of proteins from the hair, which can provide an early diagnostic for damage before it is manifested at the macro-structural level. Mike Davis will explore this approach during the Cosmetics & Toiletries Summit this June.

Visualizing the Impact of Emulsifiers on Emulsion Perception

This paper describes an approach to systematically investigate the intrinsic effects of emulsifiers, quantify them and translate them into consumer preferences. These are processed mathematically and displayed in a simplified, two-dimensional map to assist formulation work.

Role of Photography in Acne Metrics*

To optimally treat acne, an accurate severity assessment is required1 and while visual assessments have relied on text descriptions, lesion counting and photographic methods, an ideal grading system would be more accurate and reproducible. Further, its ease of use, and time and monetary costs are also important. Here, the authors consider different approaches for improved acne assessments using photography.
