Clinical tests on human skin. 20 female volunteers were treated for 28 days either with a cream containing 0.002% of AEE or with a placebo cream without the extract. The effects on skin firmness and elasticity were measured by a Cutometer and expressed in the graph as R0 and R2 parameters (a). The effects on wrinkle depth were visualized by a 3D camera and photographed (b). The error bars indicate standard deviations, * p < 0.05 compared to placebo control.
