Basic skin functions like that of a shielding barrier, homeostasis
of water, temperature regulation and photoprotection respond
to supplementary or dietary intervention with selected nutrients
(1,2). Modulated functions are accompanied by changes in
cutaneous structure and texture which affect the appearance of
the skin. Studies in man have shown that an increased intake
of carotenoids such as b-carotene or lycopene, carotenoid-rich
food or flavanol-rich cocoa strengthens the basal protection
against UV-induced erythema, increases cutaneous blood flow,
and modulates skin structure and hydration
