Argan nut oil, derived from the kernels of the Argan tree (Argania spinosa), has a long history of traditional use in Morocco for skin care, largely due to its moisturizing and purported healing properties. In recent years, scientific studies have investigated these claims, focusing on the oil’s biochemical composition and effects on skin health. Argan oil is rich in fatty acids (notably oleic and linoleic acids), vitamin E (tocopherol), and polyphenols, all of which are known to contribute to skin barrier function and antioxidant defense.

Scientific evidence supports its use in improving skin hydration and elasticity. Studies have shown that topical application of Argan oil increases skin moisture and reduces roughness in both healthy and postmenopausal women. The antioxidant properties of vitamin E and polyphenols may help protect the skin from oxidative stress and photoaging. Some small clinical trials and in vitro research suggest minor benefits in wound healing and reduction of inflammation, though these effects are less well established in humans.

While most studies are small and sometimes lack rigorous controls, the cumulative evidence suggests that Argan oil can be beneficial as a moisturizing and protective agent in skin care. However, strong clinical evidence for its efficacy in treating specific skin disorders (e.g., eczema, psoriasis) is limited. Thus, its use for general skin care is supported by both traditional use and moderate scientific validation.
