Volar forearm water content of epidermis (WCE) evolution after oils consumption and/or argan oil application. A) At the right volar forearm (RF) in the group consuming argan oil, B) at the right volar forearm (RF) in the group consuming olive oil, C) at the left volar forearm (LF) in the group consuming argan oil, D) at the left volar forearm (LF) in the group consuming olive oil. The difference between the 3 paired means (± SD) of WCE (taken at D0, D30 and D60) of the two volar forearms (RF and LF) of each group (argan and olive) were analyzed using ANOVA test for repeated measures followed by Bonferroni post-hoc test (if ANOVA test for repeated measures was statistically significant). p < 0.05 was considered statistically significant (results of ANOVA test for repeated measures). NS – ANOVA test for repeated measures shows no statistically significant difference (p > 0.05). *p < 0.05 was considered statistically significant (results of Bonferroni post-hoc test)
