INCI: Helianthus Annuus Seed Oil

Helianthus Annuus Seed Oil is a lightweight plant oil cold-pressed from sunflower seeds (Helianthus annuus L., Compositae family). It is exceptionally rich in linoleic acid (50–74%) and oleic acid (14–35%), fatty acids that closely mimic the skin's own lipid barrier. It works primarily as an emollient, smoothing and softening the skin surface while forming a light occlusive film that helps lock in moisture and support barrier repair.
