The effects of Lavandula angustifolia extract fermented with Pediococcus pentosaceus DK1 on UVB-mediated MMP-1 expression and collagen decrease in human skin fibroblasts were determined, and the conversion of its components was also analyzed. Fermentation was performed at varying L. angustifolia extract and MRS medium concentrations, and optimal fermentation conditions were selected. L. angustifolia extracts showed decreased cytotoxicity after fermentation in the fibroblasts. UVB-irradiated fibroblasts treated with fermented L. angustifolia extract showed MMP-1 expression 8.2-14.0% lower than that in UVB-irradiated fibroblasts treated with non-fermented extract. This was observed even at fermented extract concentrations lower than those of non-fermented extracts. Fibroblasts treated with fermented L. angustifolia extract showed 20% less reduction in collagen production upon UVB irradiation than those treated with non-fermented extracts. UVB-irradiated fibroblasts treated with fermented L. angustifolia extracts showed 50% higher inhibition of ROS generation than those treated with non-fermented extract. Luteolin and apigenin glycosides of L. angustifolia were converted during fermentation, and identified using RP-HPLC and LC/ESI-MS. Therefore, the effects of L. angustifolia extract on MMP-1 expression and collagen decrease in UVB-irradiated human skin fibroblasts were increased through fermentation by P. pentosaceus.
