A Melanin Derivative to Shield the Skin from High Energy Visible Light
By: N. Dayan, PhD, Lipo Chemicals Inc.; A. Ballant…
High energy visible (HEV) light recently has been suspected of causing as much damage as UVA and UVB combined. Thus, the present paper describes a fractionated melanin tailored to absorb light in the visibile 400–500 nm range. In addition, because the material exhibits color, the authors focus on formulation techniques to incorporate it into semi-solid formulations.

Au Naturale Nanoparticle Sun Protection
By: Katie Schaefer, C&T magazine
In 1876, Charles Darwin observed the secretion of yellow matter from the rootlets of ivy. Little was known about the material until 2008, when Mingjun Zhang, PhD, an associate professor of biomedical engineering at the University of Tennessee, and his research team found nanoparticles in the yellow matter.

Silicon Microspheres as UV, Visible and Infrared Filters for Cosmetics
By: Isabelle Rodriguez, PhD, Roberto Fenollosa, Ph…
Silicon microspheres are described as UV, visible and infrared (IR) radiation filters. Parameters of these spheres including shape, smoothness, refractive index and size are examined for their potential benefits in cosmetic formulations. Finally, the ability of the spheres to block IR radiation is evaluated for thermo-regulatory effects.
