Antiwrinkle effects of STEE in vitro. The antiwrinkle effect of STEE was determined by gelatinolytic activities of MMP-2 and MMP-9 in L929 cells using gelatin zymography (a) and the inhibitory effects of STEE on collagenase and elastase (b). Means with different letters (A–C) differ significantly ().
