Oenothera Biennis (Evening Primrose) Seed Extract is a botanical oil derived from the cold-pressed seeds of the evening primrose flower, prized for its exceptionally high content of linoleic acid (60–85%) and gamma-linolenic acid (GLA, 7–12%), essential omega-6 fatty acids that the skin cannot synthesize. This lightweight, non-comedogenic extract delivers deep moisturization by reinforcing the lipid barrier and reducing transepidermal water loss, while its anti-inflammatory and antioxidant properties soothe redness and support skin repair, making it ideal for dry, sensitive, or inflammation-prone complexions. In formulations, it functions as an emollient and skin-conditioning agent, enhancing elasticity and promoting barrier resilience against environmental stressors.
