Patent Pick: Matte Makeup and the Feel of Fillers

Matte makeup stands strong in its ability to even out skin tone and absorb excess moisture but wavers in one area: the feel of fillers. This was the focus of a new L'Oréal patent.

Characterizing and Evaluating the Effectiveness of Volcanic Pumice Exfoliants

Pumice has a recognized application as an abrasive agent to promote exfoliation of the skin. In this study, different particle size fractions of pumice sampled from several geologic occurrences in São Miguel’s island, the Azores archipelago, were used in the preparation of exfoliation formulations. Gels and soap were prepared and characterized, and their efficacy evaluated.

Effects of Occlusion (III): Irritant and Allergic Contact Dermatitis

This is the third article in a series discussing effects of occlusion on skin. Previously, we reviewed the effects of occlusion on the percutaneous absorption (C&T November 2003) and on wound healing (C&T April 2004). The present article focuses and summarizes the adverse effects of occlusion. Occlusion enhances skin hydration and increases percutaneous absorption of applied substances with exception. On the other hand, it may also increase the penetration of irritants and/or antigens entering into skin and hence may increase irritant and allergic contact dermatitis. Additionally, occlusion compromises skin barrier function by impairing passive transepidermal water loss at the application site, and hence aggravates the irritant effect of applied compounds.

Penetration of Cosmetics Into and Through the Stratum Corneum

The penetration routes of substances through the stratum corneum and how these transport pathways function are becoming better understood. Despite this progress, however, the penetration mechanisms of cosmetic formulations remain mysterious. This overview presents current knowledge on the various pathways of penetration, and suggests that even if cosmetic formulations penetrate no deeper than the surface, their efficacy may still be optimal.

Consumer Perception of Fine Lines and Wrinkles: Qualitative Assessment

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.

Hidden Hair Damage and the Importance of Multiple Tests

It is of paramount importance for hair researchers to know the history of hair at the time of applying a treatment. The lack of such knowledge can create misleading results. Thus, a stress-strain test in both dry and wet states can provide a rapid means to check the reliability of the information collected, as is shown here.

Hair Conference Investigates Biology and Material Science of Hair

A running joke has developed at past hair science meetings that the hair research world comprises two camps– “The Friends of the Follicle,” whose focus resides in the biology, and “The Dead Fiber Club,” whose interest lies with the complex material science of this remarkable substrate.

Words from Wiechers: Too Often, Too Hot and Too Long. . .

In this edition of Words from Wiechers, product developers are reminded that if consumers deplete natural moisturizing factor from their skin, e.g., via long, hot showers, they damage their barrier and increase the penetration of anything applied to skin; including mild cleansers.
