Product Description
Evening Primrose Oil is a nutrient-rich essential fatty acid oil valued in natural formulations for its ability to support skin renewal and repair. Pressed and gently refined, this golden oil is a favourite for caring for dry, rough skin, thanks to its deeply emollient and nourishing properties.
Closely related to Borage Oil, Evening Primrose is a valued source of Gamma Linolenic Acid (GLA) (typically 9% or more), alongside linoleic acid (60–85%). Once metabolised, the triacylglycerols release GLA, which plays a vital role in maintaining healthy skin function, elasticity, and tissue regeneration.
In topical formulations, Evening Primrose Oil helps support barrier function, soothes dry skin, and promotes a smoother, more supple complexion.
INCI: Oenothera Biennis Oil
Frequently asked questions
What is refined evening primrose oil?
It is the fixed oil from the seeds of evening primrose, Oenothera biennis (INCI: Oenothera Biennis Oil), pressed and then refined. It is of Chinese origin, Kosher certified and suitable for both cosmetics and food.
What is the difference between refined and cold pressed organic evening primrose oil?
Refining gives a paler, lighter oil with very little scent and a consistent profile, ideal for creams and larger batches. The cold pressed organic grade is unrefined, keeping more natural colour and character, for brands making organic or minimally processed claims.
Why do formulators use evening primrose oil?
It is naturally rich in omega-6 fatty acids, including gamma-linolenic acid (GLA), and gives a light, silky emollient feel suited to dry and mature skin products. As a polyunsaturated oil it is best stored cool and sealed, with an antioxidant such as vitamin E.
