As flavanols have antioxidants, anti-inflammatory and anti-DNA damaging effects and may increase microcirculation in skin, the purpose of the study is to investigate the chronic effect of flavanol-rich chocolate as an effective strategy to protect against the harmful effect of ultraviolet (UV) radiation.

Recent data suggested that chronic ingestion of high flavanols cocoa might be a promising agent for dietary photo protection against UV light. Moreover, flavanols-rich cocoa intake has been shown to increase microcirculation in human skin.
