Carotenoids and Dermoaesthetic Benefits: Public Health Implications

Abstract

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.
