Prolonged exposure to solar ultraviolet A (UVA) radiation has been known to cause premature skin aging (photo-aging). UVA radiation generates ROS thereby induce degenerative changes of skin such as degradation of dermal collagen, elastic fibers. Matrix metalloproteinases (MMPs), the proteolytic enzymes have been implicated as a major player in the development of UVA-induced photo-aging. Many studies have been conducted to block the harmful effects of UV radiation on the skin. Recently, we are interested in the availability of fermented red ginseng (FRG) as natural matrix metalloproteinases inhibitors (MMPIs). The efficacy difference between red ginseng and FRG has been compared. Both RG and FRG have no cytotoxic effects below the concentration of 300 μg/ml. Human dermal fibroblasts (HDFs) were pretreated with FRG or RG for 24h, followed by irradiation of UVA. Then, we measured the intracellular ROS production and the expression of MMP, IL-1β at the mRNA level. We also examined the intracellular localization of NF-κB and MMP-9 on the FRG or RG treated and UVA-irradiated HDFs. FRG decreased the intracellular ROS production elicited by UVA. In addition, FRG decreased the mRNA expression of MMP-3, MMP-9, and IL-1β more efficiently than RG. Furthermore, FRG suppressed the nuclear localization of NF-κB, and the expression of MMP-9. Taken together, our results suggest that FRG is promising agents to prevent UVA-induced photo-aging by suppressing MMP expression and inflammation.
