Fig. 3From: Anti-wrinkle effects of Seungma-Galgeun-Tang as evidenced by the inhibition of matrix metalloproteinase-I production and the promotion of type-1 procollagen synthesisEffects of SMGGT on MMP-1 production (a) and type-1 procollagen synthesis (b) in UVB-non-irradiation or UVB-irradiation (40 mJ/cm2) group of human dermal fibroblasts. Cells were treated with various concentrations of SMGGT water extract or L-ascorbic acid for 48 h, and then cell supernatants were collected for ELISA kit. Statistical significance for the results were given as *p < 0.05; **p < 0.01 and ***p < 0.001. L-Ascorbic acid was used as a positive control and the results were normalized with cell numbers that were confluentBack to article page
