Evening Primrose Flower Extract (Oenothera Biennis Flower Extract) is an aqueous or hydroglycolic extract of evening primrose flowers. Composition differs from evening primrose oil (which is from seeds): less gamma-linolenic acid (GLA), more flavonoids (quercetin, kaempferol) and phenolic acids. Mechanism. Antioxidant action via free radical neutralization. Mild anti-inflammatory effect. Where applied. Serums and creams for sensitive and mature skin, anti-inflammation products. Concentration 0.5–3%. Less common than evening primrose oil. Evidence base. Virtually no human clinical RCTs of the flower extract – most evidence covers seed oil (GLA). CIR confirmed safety. Pregnancy and lactation – no data. No published studies of topical flower extract in pregnancy. Manufacturers recommend avoidance.
