Abstract

Polyphenols are a unique group of phytochemicals that are present in a large number of fruits, vegetables, and other plant products. They are classified according to their chemical structure, which contains multiple linked phenol groups [1]. These compounds have powerful antioxidant properties that counteract harmful free radicals in the body. Nutrition has long been identified as a critical factor of health and well being, and the investigation into the costs and benefits of ingesting certain compounds has just begun; polyphenols in particular have been a topic of interest since the discovery that they may prevent or even reverse the effects of photoaging due to ultraviolet radiation [2]. Here, we explore the various types and properties of polyphenols, the deleterious effects of free radicals on skin health, and the possible protective and regenerative ability of dietary polyphenols.
