A fixed plant seed oil obtained from Oenothera biennis seeds. It is a triglyceride-rich emollient naturally high in linoleic acid and gamma-linolenic acid (GLA), with a skin-conditioning, barrier-supportive profile. In cosmetics it is used to soften skin, reduce dryness, and improve the feel of formulas. It is most often used in leave-on skincare and hair products rather than rinse-off systems.
