(a) Skin Capacitance/SC hydration, (b) skin erythema, (c) pH-value, (d) transepidermal waterloss and their absolute change within 30 days of twice daily cream application of ethanol-free and 12% ethanol containing creams. The gray graphs represent the ethanol-containing formulation and the red graphs the ethanol-free formulation. Neither for the individual creams nor in comparison with each other is there any difference between ethanol-containing and ethanol-free formulations in their effect on the measured parameters n = 9; Boxplot with the median (horizontal line within the box) and the mean (non-filled square). Upper and lower whiskers indicate the minimum and maximum within 1.5 times the interquartile range.
