2. Figure 1
Weighted linear regression analyses (through the origin) for cumulative mass of stripped SC as a function of tape strip number i (error bars: ±σ). Symbols represent the measurements, and lines represent the regression results. The derived regression functions (slope ± SD) and correlation coefficients for abdomen and forearm of a single volunteer are given. Thus, for a given volunteer and anatomical site each tape strip removed approximately the same mass of SC.

3. Figure 2
Linear regression analyses of 1000/TEWL versus thickness of stripped SC x for the abdomen (a) and volar forearm (b). Symbols represent the measurements, and lines represent the regression results. The linearity confirms that human SC may be regarded as a Fickian membrane for water diffusion.
