Skin firmness, the primary efficacy variable, was assessed at the start of the trial and after treatment for 28 days using a devise to measure shear wave propagation in the skin, Reviscometer RVM 600[R] (Courage + Khazaka Electronic, Cologne, Germany), for recording Resonance Running Time, RRTM, expressed in arbitrary time units.
