Oenothera Biennis Flower … Stem Extract

Oenothera biennis, commonly known as evening primrose, is a herbaceous plant native to North America. The extract used in skincare is derived from the flower, leaf, and stem components, and functions primarily as a skin conditioning agent.Evening primrose extract contains fatty acids and other plant compounds that are intended to help maintain skin hydration and support the skin barrier. It is used in formulations at relatively modest concentrations as part of broader skincare systems.

The extract works primarily through its emollient properties, forming a conditioning layer on the skin surface that helps reduce transepidermal water loss. The plant compounds present may also have mild antioxidant properties, though the strength of these effects in cosmetic formulations remains modest.Because the extract is plant-derived, its exact composition can vary depending on growing conditions and extraction methods, which affects how consistently it performs across different products.

Evening primrose extract is typically found in moisturisers, serums, and hydrating products rather than active treatment formulations. It works best as part of a consistent skincare routine and is unlikely to deliver significant results as a standalone ingredient. Apply as directed on product packaging, usually daily as part of your moisturising step.

Generally well-tolerated and suitable for most skin types. Those with known plant sensitivities should check the full ingredient list before use.
