“…UV screening agents used in nature to protect plants and organisms from the harmful effects of UV radiation have attracted over the past decades considerable interest. [1][2][3][4] These filters have been optimized by evolution to provide protection against UV radiation while at the same time avoiding photochemical reactions of the filter itself that might give rise to harmful side reactions. They therefore form a source of inspiration for the development of novel artificial UV filters for applications in sunscreen formulations, [5][6][7][8][9][10][11][12] but also in photothermal applications in which the energy of the photon is converted into heat that is subsequently used for tailored purposes.…”

“…Usually, commercial sunscreens contain different UV filters to obtain a formulation that is effective at protecting from the whole UV range. Serpone et al and Egambaram et al published two review papers that resume a discussion of the most common topical sunscreen agents used nowadays and consider such agents' effect on skin, the current concerns on their health and environment safety, and future perspectives in the sunscreen field [173,174]. Generally, UV filters are categorized in two classes: (i) organic or chemical filters, capable of absorbing UV radiation, and (ii) inorganic or physical filters, which reflect or scatter incident radiation.…”

Calcium phosphates (CaPs) belong to a class of biomimetic materials widely employed for medical applications thanks to their excellent properties, such as biodegradability, biocompatibility and osteoinductivity. The recent trend in the cosmetics field of substituting potentially hazardous materials with natural, safe, and sustainable ingredients for the health of consumers and for the environment, as well as the progress in the materials science of academics and chemical industries, has opened new perspectives in the use of CaPs in this field. While several reviews have been focused on the applications of CaP-based materials in medicine, this is the first attempt to catalogue the properties and use of CaPs in cosmetics. In this review a brief introduction on the chemical and physical characteristics of the main CaP phases is given, followed by an up-to-date report of their use in cosmetics through a large literature survey of research papers and patents. The application of CaPs as agents in oral care, skin care, hair care, and odor control has been selected and extensively discussed, highlighting the correlation between the chemical, physical and toxicological properties of the materials with their final applications. Finally, perspectives on the main challenges that should be addressed by the scientific community and cosmetics companies to widen the application of CaPs in cosmetics are given.

“…Sunscreen development in commercial laboratories tends to focus on achieving an acceptable bulk formulation without considering such molecular-level interactions ( Acker et al, 2014 ). However, it is clear that a better fundamental understanding of how intermolecular interactions can impact on the performance of organic sunscreens could be beneficial in the rational design of new and improved sunscreens and their optimum formulations ( Serpone, 2021 ). Over recent years, laser spectroscopy techniques have been applied to better understand how intermolecular interactions (e.g., with solvent molecules) and the local environment (pH) affect sunscreen photochemistry.…”

Sunscreens are essential for protecting the skin from UV radiation, but significant questions remain about the fundamental molecular-level processes by which they operate. In this mini review, we provide an overview of recent advanced laser spectroscopic studies that have probed how the local, chemical environment of an organic sunscreen affects its performance. We highlight experiments where UV laser spectroscopy has been performed on isolated gas-phase sunscreen molecules and complexes. These experiments reveal how pH, alkali metal cation binding, and solvation perturb the geometric and hence electronic structures of sunscreen molecules, and hence their non-radiative decay pathways. A better understanding of how these interactions impact on the performance of individual sunscreens will inform the rational design of future sunscreens and their optimum formulations.
