Argan nut oil, derived from the kernels of the Argan tree (Argania spinosa), has been traditionally used in Morocco for skin care, including as an anti-aging remedy. In recent years, some scientific studies have explored its effects on skin health, including its potential to reduce the appearance of wrinkles. Argan oil is rich in fatty acids (notably oleic and linoleic acids), vitamin E, and other antioxidants, which are believed to support the skin barrier, improve hydration, and counteract oxidative stress—factors that contribute to skin aging and wrinkle formation.

A few small clinical studies have examined Argan oil's impact on skin elasticity and hydration. For example, a 2015 randomized controlled trial published in Clinical Interventions in Aging found that daily consumption and topical application of Argan oil improved skin elasticity among postmenopausal women. However, direct evidence that Argan oil can significantly reduce wrinkles is limited, and most studies have focused on parameters like hydration and elasticity rather than visible wrinkle reduction.

In summary, while there is some scientific support for Argan oil's positive effects on general skin health, the evidence specifically supporting its use for treating or preventing wrinkles is limited and not robust. Further well-designed studies are needed to confirm its efficacy for this purpose.
