Novel Azobenzene Compound to Extend and Reactivate UV Protection

Two azobenzene compounds were synthesized and combined in liposomal membranes. Their physico-chemical properties and biocompatibility were evaluated. The safer one was chosen, and its protective function for UVA and UVB were tested in vitro and in vivo. This azobenzene liposomal formulation provided good efficacy with longer shelf life, which could be utilized as a novel kind of repeated UV absorber.

In vitro/vivo SPF Correlation and Repeatability According to Substrate

This work evaluates the impact of three different substrates on in vitro SPF measurements, and defines experimental conditions to improve their correlation with in vivo values. Evaluations of 32 products, shown here, led the authors to conclude that molded substrates improved repeatability and correlation with in vivo SPF values.

Photostabilization of Retinol and Retinyl Palmitate by Ethylhexyl Methoxycrylene

This study examines the photostability of retinol and retinyl palmitate, finding they break down rapidly when exposed to UV radiation in the 290–400 nm range. This severely reduces their concentrations in finished formulations. However, when combined with ethylhexyl methoxycrylene, these retinoids are shown to be protected against photodegradation, thus preserving their concentrations both during the manufacturing process and following application to the skin.

Inhibiting Cathepsin G to Protect Against Photoaging and Infra’aging

Ultraviolet and infrared exposure are sources of premature skin aging, characterized by solar elastosis and extracellular matrix degradation. Polygonum aviculare extract is a cathepsin G inhibitor, and is shown here to oppose photoaging and infra’aging by improving skin firmness and elasticity, in turn reducing the appearance of wrinkles.
