Oenothera Biennis (Evening Primrose) Root Extract
Oenothera Biennis (Evening Primrose) Root 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 (6–15%). The source page covers the seed oil variant; this ingredient shares the same botanical origin but is extracted from the root rather than the seeds.
Evening primrose-derived ingredients are noted for hydrating and soothing properties, with the oil form shown to help reduce inflammation and irritation, support skin cell regeneration, and benefit dry or easily irritated skin beyond simple surface occlusion.
The source data covers the seed oil (Oenothera Biennis Oil), not the root extract specifically; benefits and ratings listed for the oil may not directly apply to the root extract form.
