Endocrine disruptors (EDs) are molecules capable of mimicking the natural hormones of the body and interfering with the endocrine system in both humans and wildlife. Cosmetic products are one source of EDs; these include an extensive variety of personal care and beauty products designed for the skin and hair, as well as makeup. The widespread use of such products has raised concerns about the presence of EDs within them. In this study, we highlight the issue of EDs and analyze the functioning of the EU regulatory framework for chemicals, specifically those which act as EDs in cosmetic products. We also highlight issues related to the interface between science and policy in the critical area of risk regulation within the EU. In addition, we investigate how chemical substances that act as EDs are identified based on specific criteria and conditions, a process which involves the production and adoption of particular scientific opinions. Finally, we assess the efficiency, suitability, and effectiveness of the regulatory framework in this sensitive area of human exposure to chemicals, especially those that function as EDs.

Food technology, health, nutrition, dermatology, and aesthetics have focused on colorless carotenoids. Carotenoids are readily bioavailable and have demonstrated various health-promoting actions. This article reviews the recent literature concerning carotenoids with the aim to systematize the scattered knowledge on carotenoids and aesthetics. The applications of carotenoids in health-promoting and nutrient products and their potential health effects are discussed. The carotenoids, particularly phytoene and phytofluene, have the unique ability to absorb ultraviolet radiation. Their distinct structures and properties, oxidation sensitivity, stiffness, aggregation tendency, and even fluorescence in the case of phytofluene, contribute to their potential benefits. A diet rich in carotenoid-containing products can positively impact skin health, overall well-being, and the prevention of various diseases. Future studies should focus on generating more data about phytoene and phytofluene levels in the skin to accurately assess skin carotenoid status. This expanding area of research holds promise for the development of novel applications in the fields of health and cosmetics.

This review emphasizes the significance of dietary carotenoids in promoting skin health and appearance. The applications of carotenoids in health-promoting and nutrient products and their potential health effects are discussed. Food technology, health, nutrition, dermatology, and dermoaesthetics have recently focused on colorless carotenoids, particularly phytoene, and phytofluene, which have the unique ability to absorb UV radiation. These carotenoids, being significant components of the human diet, are readily bioavailable and have demonstrated various health-promoting actions in re-cent studies. Their distinct structures and properties, such as light absorption, oxidation sensitivity, stiffness, aggregation tendency, and even fluorescence in the case of phytof-luene, contribute to their potential benefits. Furthermore, it is recommended to assess the levels of these carotenoids to evaluate skin carotenoid status accurately.
