Oenothera Biennis (Evening Primrose) Root Extract

What is Oenothera Biennis (Evening Primrose) Root Extract?

Oenothera Biennis (Evening Primrose) Root Extract comes from the underground roots of the Oenothera biennis plant, a biennial herb native to North America and widely naturalized elsewhere. The roots are processed via extraction methods like water or solvent to isolate bioactive components such as polysaccharides, flavonoids, and other plant metabolites. In cosmetic formulations, it serves as a botanical extract in the skin conditioning category. It works by forming a protective film on the skin surface, aiding moisture retention and enhancing texture without clogging pores. Commonly incorporated into creams, lotions, and serums for its humectant-like effects, it supports overall skin feel and comfort in rinse-off and leave-on products. Its mild nature makes it a staple in gentle, everyday skincare.
