Figure 1

Effect of water and the three different surfactants lecithin S75, lecithin LPC80 and SDS on transepidermal water loss (TEWL) after four days of repeated exposure. Parameter changes were calculated using Equation (1) and are expressed as single values (n = 8, SDS values n = 6) and the corresponding mean. Statistically significant differences are marked with asterisks (** p < 0.01, *** p < 0.001) and were tested with a one-way ANOVA + post-hoc Tukey test with p < 0.05 as minimum level of significance.
