What it is
This extract is obtained from the flowers of Oenothera biennis, the evening primrose, a plant better known for the fatty-acid-rich oil pressed from its seeds. In sunscreen and skincare formulas the flower extract is used at low levels as a conditioning and soothing botanical that contributes to the overall sensory and marketing positioning of the product rather than to UV protection. It is typically supplied as a water or glycol-based extract.
Safety & warnings
Botanical extracts can carry naturally occurring sensitizers and trace pollen, so individuals with plant or pollen allergies may rarely react. It is used at low concentrations and is generally well tolerated in leave-on products.
Origin & sourcing
Natural; a plant extract derived from the flowers of Oenothera biennis (evening primrose), usually prepared as an aqueous or glycolic extract.
Questions everyone asks
Is evening primrose flower extract the same as evening primrose oil?
No. The oil is pressed from the seeds and is rich in fatty acids, while this ingredient is an extract of the flowers used mainly as a conditioning and soothing additive.
Does it provide sun protection?
No. It is not a UV filter and is included for skin-conditioning and soothing purposes, not for SPF.
