Ingredient review
Evening Primrose Leaf Cell Extract
INCI: Oenothera Biennis Leaf Cell Extract
A gentle, plant-derived antioxidant that may help protect skin from environmental stress, though research is still emerging.
In plain English
This ingredient is made by growing evening primrose leaf cells in a lab, then extracting beneficial compounds. It's used in skincare to provide antioxidant protection, meaning it can help neutralize free radicals from pollution and UV exposure that can damage skin cells. Because it's produced in a controlled environment, it's consistent and sustainable, but it's a newer ingredient so long-term studies are limited.
