What Is Oenothera Biennis Flower/Leaf/Stem Extract?
Oenothera Biennis Flower/Leaf/Stem Extract comes from the evening primrose plant, a bright yellow wildflower native to North America and now grown worldwide. The flowers, leaves and stems hold a cocktail of skin friendly compounds such as gamma-linolenic acid, linoleic acid, vitamin E, flavonoids and soothing polysaccharides. Indigenous peoples applied mashed evening primrose on skin to calm irritation, and European settlers later adopted the practice. Fast-forward to modern cosmetic labs and the plant is valued for its gentle yet effective skin care properties.
Production starts with harvesting the aerial parts at peak bloom, followed by drying and grinding. The material is then steeped in a cosmetic-grade solvent like water, glycerin or propylene glycol to pull out the active molecules. After filtration the extract is standardized, preserved and added to formulations as a water-soluble ingredient.
You will typically spot Oenothera Biennis Flower/Leaf/Stem Extract in calming masks, daily moisturizers, anti-aging creams, hydrating toners, after-sun gels and leave-on treatments designed for sensitive or stressed skin.

Comedogenic Rating
Rating: 1/5. The extract is usually supplied in a water or glycerin base and contains only small amounts of fatty acids, so it rarely clogs pores. The lightweight nature and quick absorption keep residue from sitting on the skin surface and trapping debris.
Because of the low rating this ingredient is generally considered friendly for acne-prone or breakout-prone skin.
Keep in mind that the overall formula matters; if the product also contains heavier oils or thick occlusives the finished blend may feel richer than the extract itself.

While not a headline act like vitamin C or retinol, the extract shows up in a steady stream of moisturizers, serums and masks aimed at sensitive or dry complexions thanks to its gentle profile and plant-based appeal.
Current evidence points to excellent topical safety with only rare reports of irritation or allergy. Still, every skin is unique, so it is wise to patch test any new product that contains this ingredient before full application.
