Concern level

High concern

Botanical extract derived from the flowers of Oenothera biennis (evening primrose). In cosmetics it is used mainly as a plant-based skin-conditioning or astringent ingredient in botanical formulas. Like most flower extracts, it is a complex mixture rather than a single defined molecule, so exact physicochemical properties vary by supplier and extraction method.
