Summary:s Solar ultraviolet (UV) irradiation is a primary cause of premature skin aging that is closely associated with the degradation of collagens caused by up-regulation of matrix metalloproteinases (MMPs) or a decrease in collagen synthesis. The phenolic veratric acid (VA, 3,4-dimethoxybenzoic acid) is one of the major benzoic acid derivatives from fruits, vegetables and medicinal mushrooms. VA has been reported to have anti-inflammatory, anti-oxidant and photo-protective effects. In this study, anti-photoaging effects were investigated through the photo-protective mechanisms of VA against UV irradiation in human dermal fibroblasts and the reconstructed human epidermal model. We used reverse transcription-polymerase chain reaction, Western blot analysis, hematoxylin and eosin staining (H&E) and immunohistochemistry assays. Finally, we further investigated the clinical effects of VA on facial wrinkle improvements in humans. Our results demonstrate that VA attenuated the expression of MMPs, increased cell proliferation, type Ι procollagen, tissue inhibitors of metalloproteinases, and filaggrin against UV radiation; however, has no effect on improvement expressions of elastic fiber. In addition, treatment with cream containing VA improved facial wrinkles in a clinical trial. These findings indicate that VA improves wrinkle formation by modulating MMPs, collagens and epidermal layer integrity, suggesting its potential use in UV-induced premature skin aging.
