Oenothera Biennis (Evening Primrose) Oil

Evening Primrose Oil is a precious botanical oil cold-pressed from the seeds of Oenothera biennis, native to North America. It is exceptionally rich in gamma-linolenic acid (GLA, 8-10%), a rare omega-6 fatty acid that supports skin barrier function and helps manage inflammatory skin conditions. Formulators prize this oil for its ability to improve skin elasticity, reduce transepidermal water loss, and provide soothing benefits to sensitive or compromised skin, though its high polyunsaturated content requires careful preservation and antioxidant protection in formulations.
