The aim of this study was to evaluate the effect of daily consumption and/or application of argan oil on skin hydration in postmenopausal women.
Sixty postmenopausal women consumed butter during the stabilization period and were randomly divided into two groups for the intervention period: the treatment group absorbed alimentary argan oil (n = 30) and the control group olive oil (n = 30). Both groups applied cosmetic argan oil in the left volar forearm during a sixty days' period. Evaluation of skin hydration, i.e. transepidermal water loss (TEWL) and water content of the epidermis (WCE) on both volar forearms of the two groups, were performed during three visits at D0, D30 and after sixty days (D60) of oils treatment.
The consumption of argan oil has led to a significant decrease in TEWL (p = 0.023) and a significant increase in WCE (p = 0.001). The application of argan oil has led to a significant decrease in TEWL (p = 0.01) and a significant increase in WCE (p < 0.001).
Our findings suggest that the daily consumption and application of argan oil have improved the skin hydration by restoring the barrier function and maintaining the water-holding capacity.
本研究旨在评估绝经后女性每日食用和/或涂抹阿甘油对皮肤水合作用的影响。
60名绝经后女性在稳定期食用黄油，并在干预期随机分为两组：治疗组摄入食用阿甘油（n = 30），对照组摄入橄榄油（n = 30）。两组均在60天内于左前臂掌侧涂抹化妆品用阿甘油。在油类治疗的第0天、第30天和60天后（D60）进行三次访视时，对两组双侧前臂掌侧的皮肤水合作用进行评估，即经表皮水分流失（TEWL）和表皮含水量（WCE）。
食用阿甘油导致TEWL显著降低（p = 0.023），WCE显著升高（p = 0.001）。涂抹阿甘油导致TEWL显著降低（p = 0.01），WCE显著升高（p < 0.001）。
我们的研究结果表明，每日食用和涂抹阿甘油通过恢复屏障功能和维持持水能力改善了皮肤水合作用。
