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.
