As far as the public is concerned, hypothetical risks are real. And if anyone studies a chemical in depth, they can find some effect but whether it should be removed from the market comes down to a risk-benefit analysis. Cosmetic formulation is a continuous process of keeping in step with research, and when a true risk emerges, addressing it.

In humans, the ZAG protein is a modulator of fat mobilization. The present paper identifies an unroasted shea butter extract, enriched in viminalol esters, as a stimulator of ZAG expression and secretion by keratinocytes in vitro. Further, a complex containing the extract is shown to significantly improve the appearance of cellulite within 28 days of application in a clinical setting.

The present article discusses facial powder containing specific layered color-travel pigments that give a color-flop effect due to light reflectance at different angles. In particular, layering a bluish silver pigment with a sienna pigment is shown to highlight the forehead, cheek and nasal bridge while shading the jaw, chin and alar base of the nose, consequently imparting a slim-looking appearance.

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.

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.

Troubleshooting most stability concerns in cosmetic formulations typically starts at the usual raw material classes comprising the skin care and makeup ingredient list. In skin care systems, the emulsification system, thickening ingredients, actives and emollients are usually examined. In a makeup formulation, structural items such as waxes and fillers are usually reviewed, as well as film-formers and colorants.

Nanoporous organosilica particles were developed to swell upon the addition of organic solvents. These are evaluated here for encapsulating and controlling the release of fragrance. Slower, continuous release was observed, suggesting their ability to extend sensory benefits. In addition, the stimulated release of encapsulated lidocaine was studied, and results implicate their use to deliver cosmetic actives.

To improve the appearance of dry and wrinkled lips, it is necessary to hydrate them. Here, the author describes a lipstick concept to meet this need and a formulation process to achieve it. The product was then tested for immediate and long-lasting moisturization using a corneometer, and a quantitative study was conducted to rate its usability.

A novel mechanism to increase collagen production based on improved hydroxylation of the collagen fiber is described here. In relation, the effects of a hydrophobic derivative of a-ketoglutarate on this mechanism are examined, and results indicate increases in collagen production in senescent fibroblasts in vitro. In vivo, a significant reduction in wrinkles and improvement in elasticity were observed.
