Sunflower seed oil
INCI: Helianthus Annuus (Sunflower) Seed Oil
A high-linoleic-acid botanical oil that adds softness and supports the lipid film around the lash and brow hair, complementing the heavier castor base.
Evidence and limitations
Peer-reviewed work on skin shows topical sunflower seed oil supports the lipid barrier and is well tolerated; independent evidence specifically in lashes is limited, so the benefit here is conditioning and appearance.
