What is evening primrose oil and how may it support skin health?

Evening primrose oil is rich in gamma-linolenic acid (GLA), an omega-6 fatty acid that is a precursor to anti-inflammatory prostaglandins. GLA deficiency has been proposed as a factor in atopic dermatitis. Some clinical studies suggest evening primrose oil may improve skin moisture and reduce itching in eczema, though results are mixed.

What dosage of evening primrose oil has been studied for skin conditions?

Clinical trials have used 2–6 grams of evening primrose oil per day, providing 160–480 mg of GLA. Studies for atopic dermatitis typically used 3–6 grams daily for 8–16 weeks. A Cochrane review found insufficient evidence to recommend it for eczema, though individual responses may vary.

What are the potential side effects of evening primrose oil?

Common side effects include headache, digestive upset, and nausea. Evening primrose oil may lower the seizure threshold and should be avoided by individuals with epilepsy. It may increase bleeding risk with anticoagulants. Pregnant women should avoid it due to potential cervical ripening effects. May interact with blood pressure medications.

About

Evening primrose oil is a rich source of gamma-linolenic acid (GLA, 7-14%), an omega-6 fatty acid metabolized to anti-inflammatory DGLA and prostaglandin E1. A Cochrane review found insufficient evidence overall, but some individual RCTs showed improvement in eczema itch and dryness.

How It Works

Rich source of gamma-linolenic acid (GLA, 7-14%), an omega-6 fatty acid metabolized to anti-inflammatory dihomo-gamma-linolenic acid (DGLA) and prostaglandin E1; supports skin barrier lipid synthesis and may modulate atopic inflammation.
