Oenothera Biennis (Evening Primrose)
What is Oenothera Biennis (Evening Primrose)?
Oenothera biennis, known as evening primrose, is a flowering plant native to North America, with seeds that yield a nutrient-rich oil used in skincare. This botanical ingredient belongs to the emollient and skin-conditioning category in cosmetics. It functions by supplying polyunsaturated fatty acids, particularly linoleic acid and gamma-linolenic acid (GLA), which resemble the lipids naturally found in the skin's barrier. These components help restore suppleness, enhance moisture retention, and protect against oxidative stress. Commonly incorporated into creams, serums, oils, and hair products at low concentrations, it supports overall skin and scalp nourishment without clogging pores. Its composition also includes tocopherols, contributing to stability and mild protective effects in formulations.
