Figure 3 Volar forearm R2 (gross-elasticity of the skin) evolution.
Notes: Evolution after oils consumption and/or argan oil application at (A) the RF in the group consuming argan oil, (B) the RF in the group consuming olive oil, (C) the LF in the group consuming argan oil, and (D) the LF in the group consuming olive oil. The difference between the three paired means (± SD) of R2 (taken at D0, D30, and D60) of the two volar forearms (RF and LF) of each group (argan and olive) was analyzed using the ANOVA test for repeated measures followed by the Bonferroni post hoc test (if the ANOVA test for repeated measures was statistically significant). P<0.05 was considered statistically significant (for the results of the ANOVA test for repeated measures). NS: ANOVA test for repeated measures showed no statistically significant difference (P>0.05). *P<0.05 was considered statistically significant (for the results of the Bonferroni post hoc test).
Abbreviations: ANOVA, analysis of variance; D0, before starting oil consumption and application; D30, after 30 days of oil consumption and application; D60, after 60 days of oil consumption and application; LF, left volar forearm; NS, no significant difference; RF, right volar forearm; SD, standard deviation; Ua/Uf, gross-elasticity of the skin, including viscous deformation.
