In any sun protection evaluation method, an irradiation step is required to determine the photostability of the UV filters in a product. The aim of this study was to identify key parameters involved to improve this UV exposure. Here, the authors consider temperature at the substrate surface, air flow influence and beam uniformity during UV exposition.

There is general agreement on elastin’s role in skin health, aging and appearance, but no method has yet elucidated how it degrades with aging when challenged by sun exposure or other means. This paper reviews two inconsistent theories in the literature, degradation and buildup, and highlights potential methods to marry the two. It also suggests proteomics as a method for further investigation.

Dandruff remains a significant yet poorly served chronic scalp disorder for which more effective treatments are required. Here, lysine polypeptides are demonstrated in vitro and in vivo to effectively address the causative organism in dandruff, Malassezia spp., and provide a potential basis for new treatments to counteract this condition.

Titanium dioxide (TiO2) is known to be photocatalytically active. Even with surface modifications, it catalyzes the decomposition of organic materials and promotes the formation of reactive oxygen species. However, a particular propenoic acid ester is shown here to protect TiO2 from inducing such reactions, making it a more effective and safer UV filter.

Coral powder has applications in cosmetics but its use has impacted the marine environment. Fossilized coral could provide a sustainable alternative for uses such as fillers, cleansing and whitening agents, astringents, sebum absorbers, or to supply trace minerals to skin. Its use as an exfoliant it particularly noteworthy as formulators seek natural alternatives to polyethylene beads.

A previous article discussed traditional measurements to assess the properties of hair spray products. However, the properties of polymer films deposited by these products are not constant and can be altered by both formulation means and environmental conditions. This article highlights additional useful measurement techniques for characterizing these film properties.
