There is compelling evidence that Infrared A (IRA) from natural sunlight contributes to photoaging of human skin by inducing the expression of matrix metalloproteinase-1 (MMP-1) expression in human dermal fibroblasts. Corresponding mechanistic studies have shown that IRA does so by increasing the production of reactive oxygen species in irradiated cells. In the present study, we therefore asked if treatment of primary human skin fibroblasts with a blueberry-derived antioxidant matrix (BerrimatrixTM), which is employed as an active ingredient in commercially available skin care products that are topically applied, can prevent IRA-induced MMP-1 expression in these cells. In this in vitro study, we have found that this antioxidant containing matrix is well tolerated by fibroblast over a broad concentration range and that it efficiently prevents IRA-induced MMP-1 mRNA expression. It may thus be speculated that topical application of this antioxidant containing matrix may be efficient in protecting human skin against IRA-induced wrinkle formation.
