The use of Argan tree (specifically, argan oil derived from Argania spinosa kernels) for treating acne is supported by some emerging scientific evidence, though the body of research remains limited and preliminary. Argan oil is traditionally used in Morocco for various dermatological conditions, but its application for acne has only recently been explored in scientific studies. The oil contains a high concentration of fatty acids (mainly oleic and linoleic acids), tocopherols (vitamin E), and other antioxidants. Some clinical studies and in vitro research suggest that linoleic acid can help reduce sebum levels and decrease inflammation, both of which are relevant to acne pathogenesis.

Small-scale clinical trials and pilot studies have shown that topical application of argan oil may reduce sebum production and improve skin moisture, potentially benefiting individuals with mild acne. For example, a 2014 study found that regular application of a cream containing argan oil decreased sebum production and improved the appearance of oily skin, which can help manage acne symptoms. However, there is a lack of large-scale, high-quality randomized controlled trials specifically evaluating argan oil’s effectiveness for acne treatment.

In summary, while traditional use is present, the application for acne has some scientific backing, though the overall quality and quantity of evidence is still modest, justifying a rating of 2 out of 5.
