Evening primrose oil (EPO) is commonly used for supporting dry and/or flaky skin, with its use backed by both traditional practices and some scientific investigation. The oil is rich in gamma-linolenic acid (GLA), an omega-6 fatty acid thought to play a role in maintaining healthy skin barrier function and hydration. Several small clinical studies have explored its efficacy, particularly in conditions like atopic dermatitis (eczema) and generalized dry skin.

Some randomized controlled trials have suggested that oral supplementation with EPO may help improve skin moisture, elasticity, and reduce transepidermal water loss, especially in individuals with deficiencies in essential fatty acids. For example, a double-blind, placebo-controlled study published in the International Journal of Cosmetic Science in 2005 found a modest improvement in skin moisture and elasticity after 12 weeks of EPO supplementation.

However, the overall quality of evidence is low to moderate, and systematic reviews and meta-analyses have found inconsistent results, with some studies showing no significant benefit over placebo for eczema and dry skin. Major dermatology guidelines generally do not recommend EPO as a first-line treatment due to insufficient robust evidence. Nonetheless, its favorable safety profile and long history of use make it a popular complementary option.

In summary, while there is some scientific support for the use of evening primrose oil in managing dry or flaky skin, the evidence is not strong, and further large, well-controlled studies are needed to clarify its effectiveness.
