Oenothera Biennis (Evening Primrose) Flower Extract
Oenothera Biennis Flower Extract is derived from the evening primrose plant (Oenothera biennis, Onagraceae). The closely related seed oil form is rich in linoleic acid (66–76%) and gamma-linolenic acid (GLA, 7–12%), as well as oleic acid. It is classified as an emollient in official CosIng functions. Note: the source page describes the seed oil (Oenothera Biennis Oil), not specifically the flower extract; this profile is based on that closely related ingredient data.
Evening primrose is a hydrating plant-derived ingredient that can reduce inflammation and irritation. It is noted as a healing agent that may support dry skin not only by surface occlusion but by initiating structural changes within the skin and supporting skin cell regeneration. It is considered particularly beneficial for dry, easily irritated skin.
The source does not list specific cautions or contraindications for topical use.
