Correlations of BMI with epidermal functions. a Correlation of BMI with TEWL. b Correlation of BMI with stratum corneum hydration. c Correlation of BMI with skin surface pH. Pearson r analysis is used to determine the significance of correlation of BMI with epidermal functions. p values are indicated in the figures. For epidermal function, the number of subjects in each group is the same as in Figure 1. For BMI, N = 804 for females and N = 601 for males.
