Improving the UV Exposure of Sunscreen During In vitro Testing

By: Sébastien Miksa, Dominique Lutz and Céline Guy…

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.

Skin Aging at the Functional Proteomics Level: Elastin as a Marker

By: Nava Dayan, PhD, Dr. Nava Dayan LLC; and Matth…

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.

Photoprotection of TiO2 Using Propenoic Acid Esters

By: Robert S. Hu, Jean Zhang, Gary A. Neudahl and …

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.
