Flavonoid-rich nutrients for the skin

Abstract

Flavonoids are a group of widespread plant constituents available from dietary sources such as cocoa, green tea, soy, berries, or other fruits like apples, lemons, cherries, plums, and peaches. There is evidence that flavonoid-rich products contribute to the protection of skin against UV-induced damage at the molecular and cellular level and that they may as well improve overall skin conditions. Regular intake or topical application confers significantly to photoprotection and helps maintaining skin health by improving skin structure and function. Photoprotective effects mediated by flavonoids are moderate but likely contribute to permanent, overall protection. Effects are comparable to those reported for other dietary constitutents such as carotenoids and other antioxidants. © 2011 Springer- Verlag Berlin Heidelberg.
