Effect of ASE associated with UV-induced MMP-1 expression on human primary fibroblasts. (a) Matrix metalloproteinase-1 expression in UVB-irradiated human primary fibroblasts treated with or without ASE. (b) Effect of ATRA or retinol (ROL) plus ASE on matrix metalloproteinase-1 expression. * and ** compared with the UVB-irradiated group.
