From: Skin hydration dynamics investigated by electrical impedance techniques in vivo and in vitro

Normalized electrical impedance of skin measured with the four electrode Franz cell setup (4E) during 180 min of hydration exposure. (A) conductance at 251 kHz, (B) 1 kHz resistance, (C) MIX parameter. Experimental data is fitted with a power law. Error bars represent ± SEM (n = 5).
