Skin aging can be attributed to photoaging (extrinsic) and chronological (intrinsic) aging. Photoaging and intrinsic aging are induced by damage to human skin attributable to repeated exposure to ultraviolet (UV) irradiation and to the passage of time, respectively. In our

Diets rich in eicosapentaenoic acid [EPA; 20:5(n-3)] are associated with decreased arterial stiffness, but postprandial effects on vascular function are unknown. We investigated whether an EPA-enriched high-fat meal could improve postprandial vascular function. Seventeen healthy men ingested 2 test meals

Ultraviolet (UV) irradiation regulates UV-responsive genes, including matrix metalloproteinases (MMPs). Moreover, UV-induced MMPs cause connective tissue damage and the skin to become wrinkled and aged. Here, we investigated the effect of eicosapentaenoic acid (EPA), a dietary omega-3 fatty acid, on
