Resumo(s)
Psychological stress (or simply “stress”) is a major contributor to chronic disease worldwide, affecting 35% of the global population, including younger generations. Furthermore, it plays a significant role in human premature aging; hence, its detrimental effects on people's health compel us to comprehend and control the ways in which psychological stress impacts our bodies, including our skin. For example, flavonoids, a class of polyphenolic phytochemicals, are an important group of plant secondary metabolites and appear as a promising solution. These compounds exhibit a number of general biological activities, such as anti-inflammatory and antioxidant properties, as well as certain skin-specific ones, like wound healing, photoprotection, and the treatment of inflammatory and cancerous disorders associated with the skin. For this reason alone, flavonoids could be regarded as a promising solution. Further, these substances have demonstrated beneficial effects on the different hallmarks of aging, demonstrating their potential as anti-aging agents. They also have the ability to influence hormones linked to stress, which, considering their effects on skin health and aging mechanisms, seems to suggest that flavonoids may be effective ways to mitigate the negative effects of stress on premature skin aging. Therefore, this review seeks to demonstrate the potential of flavonoids as potential anti-aging agents for the skin, either by improving the so-called hallmarks of aging or by directly protecting the skin from external aggressors like UV radiation while reducing the negative effects of psychological stress and its known mediators.
