Abstract

BACKGROUND:

During menopause, the decrease of estrogenic secretion induces the disruption of skin functioning, thus causing the decline in skin elasticity characteristic of skin aging. The purpose of this study was to evaluate in postmenopausal women the effect of daily consumption and/or application of argan oil on skin elasticity.

MATERIALS AND METHODS:

Sixty postmenopausal women consumed butter during the stabilization period and were randomly divided into two groups for the intervention period: the treatment group of 30 participants received dietary argan oil, the control group of 30 participants received olive oil, and both groups applied cosmetic argan oil in the left volar forearm during a 60-day period. Assessments of skin elasticity parameters, ie, the three R-parameters (R2 or gross-elasticity of the skin, R5 or net elasticity of the skin, and R7 or biological elasticity), and the resonance running time (RRT) at both volar forearms of the two groups were performed during three visits: before starting oils consumption and application, after 30 days of oils consumption and application, and after 60 days of oils consumption and application.

RESULTS:

The consumption of argan oil led to a significant increase of gross-elasticity of the skin (R2) (P<0.001), net elasticity of the skin (R5) (P<0.001), biological elasticity (R7) (P<0.001), and a significant decrease of RRT (P=0.002). The application of argan oil led to a significant increase of gross-elasticity of the skin (R2) (P<0.001), net elasticity of the skin (R5) (P<0.001), biological elasticity (R7) (P=0.001), and a significant decrease of RRT (P<0.001).

CONCLUSION:

Our findings suggest that the daily consumption and/or topical application of argan oil have an anti-aging effect on the skin demonstrated by the improvement of skin elasticity, characterized by an increase of R-parameters (R2, R5, and R7) and a decrease of RRT.
