Fig. 2From: Anti-wrinkle effects of Seungma-Galgeun-Tang as evidenced by the inhibition of matrix metalloproteinase-I production and the promotion of type-1 procollagen synthesisCell viability test of SMGGT in human skin dermal fibroblast cells. Human dermal fibroblasts were cultured in DMEM until 80Â % confluence. Cells were treated with various concentrations of SMGGT water extract for 48Â h, after which the MTT assay was performed. Data are expressed as a percentage of the control (without SMGGT). Each evaluation was performed in triplicateBack to article page
